## Run an application on golang http server, and mysql database and redis datastore(can use as cache).
|
||||
|
||||
Project Structure:-
|
||||
```
|
||||
├── Dockerfile
|
||||
├── go.mod
|
||||
├── main.go
|
||||
├── go.sum
|
||||
├── docker-compose.yml
|
||||
├── makefile
|
||||
├── vendor
|
||||
└── README.md
|
||||
```
|
||||
|
||||
### docker-compose.yml
|
||||
The compose file define an application with three services `app` , `mysql` and `redis`. The application is deployed on port 8080 and it maps port 3307 for mysql and 6378 for redis on host, so if you have other instance of mysql or redis running already on port 3306 and port 6379, then also the application will run fine.
|
||||
|
||||
### makefile
|
||||
The default goal for make is help, and it looks like this
|
||||
```
|
||||
Usage:
|
||||
make [target...]
|
||||
|
||||
Useful commands:
|
||||
build to build the project again after making changes
|
||||
compose to run the containers
|
||||
down docker-compose down
|
||||
pruneVolume remove all dangling volumes
|
||||
runLocal to run the app locally
|
||||
```
|
||||
|
||||
### To run the containers
|
||||
```
|
||||
make compose
|
||||
```
|
||||
this will remove all the dangling volumes first, then build the project using flag no-cache, and then run the containers.
|
||||
|
||||
### expected result
|
||||
```
|
||||
docker container ls
|
||||
```
|
||||
```
|
||||

## Version 1.2 (2014-06-03)
|
||||
|
||||
Changes:
|
||||
|
||||
- We switched back to a "rolling release". `go get` installs the current master branch again
|
||||
- Version v1 of the driver will not be maintained anymore. Go 1.0 is no longer supported by this driver
|
||||
- Exported errors to allow easy checking from application code
|
||||
- Enabled TCP Keepalives on TCP connections
|
||||
- Optimized INFILE handling (better buffer size calculation, lazy init, ...)
|
||||
- The DSN parser also checks for a missing separating slash
|
||||
- Faster binary date / datetime to string formatting
|
||||
- Also exported the MySQLWarning type
|
||||
- mysqlConn.Close returns the first error encountered instead of ignoring all errors
|
||||
- writePacket() automatically writes the packet size to the header
|
||||
- readPacket() uses an iterative approach instead of the recursive approach to merge splitted packets
|
||||
|
||||
New Features:
|
||||
|
||||
- `RegisterDial` allows the usage of a custom dial function to establish the network connection
|
||||
- Setting the connection collation is possible with the `collation` DSN parameter. This parameter should be preferred over the `charset` parameter
|
||||
- Logging of critical errors is configurable with `SetLogger`
|
||||
- Google CloudSQL support
|
||||
|
||||
Bugfixes:
|
||||
|
||||
- Allow more than 32 parameters in prepared statements
|
||||
- Various old_password fixes
|
||||
- Fixed TestConcurrent test to pass Go's race detection
|
||||
- Fixed appendLengthEncodedInteger for large numbers
|
||||
- Renamed readLengthEnodedString to readLengthEncodedString and skipLengthEnodedString to skipLengthEncodedString (fixed typo)
|
||||
|
||||
|
||||
## Version 1.1 (2013-11-02)
|
||||
|
||||
Changes:
|
||||
|
||||
- Go-MySQL-Driver now requires Go 1.1
|
||||
- Connections now use the collation `utf8_general_ci` by default. Adding `&charset=UTF8` to the DSN should not be necessary anymore
|
||||
- Made closing rows and connections error tolerant. This allows for example deferring rows.Close() without checking for errors
|
||||
- `[]byte(nil)` is now treated as a NULL value. Before, it was treated like an empty string / `[]byte("")`
|
||||
- DSN parameter values must now be url.QueryEscape'ed. This allows text values to contain special characters, such as '&'.
|
||||
- Use the IO buffer also for writing. This results in zero allocations (by the driver) for most queries
|
||||
- Optimized the buffer for reading
|
||||
- stmt.Query now caches column metadata
|
||||
- New Logo
|
||||
- Changed the copyright header to include all contributors
|
||||
- Improved the LOAD INFILE documentation
|
||||
- The driver struct is now exported to make the driver directly accessible
|
||||
- Refactored the driver tests
|
||||
- Added more benchmarks and moved all to a separate file
|
||||
- Other small refactoring
|
||||
|
||||
New Features:
|
||||
|
||||
- Added *old_passwords* support: Required in some cases, but must be enabled by adding `allowOldPasswords=true` to the DSN since it is insecure
|
||||
- Added a `clientFoundRows` parameter: Return the number of matching rows instead of the number of rows changed on UPDATEs
|
||||
- Added TLS/SSL support: Use a TLS/SSL encrypted connection to the server. Custom TLS configs can be registered and used
|
||||
|
||||
Bugfixes:
|
||||
|
||||
- Fixed MySQL 4.1 support: MySQL 4.1 sends packets with lengths which differ from the specification
|
||||
- Convert to DB timezone when inserting `time.Time`
|
||||
- Splitted packets (more than 16MB) are now merged correctly
|
||||
- Fixed false positive `io.EOF` errors when the data was fully read
|
||||
- Avoid panics on reuse of closed connections
|
||||
- Fixed empty string producing false nil values
|
||||
- Fixed sign byte for positive TIME fields
|
||||

||||
made, import, or transfer of either its Contributions or its
|
||||
Contributor Version.
|
||||
|
||||
1.12. "Secondary License"

|
||||
means an individual or a legal entity exercising rights under this
|
||||
License. For legal entities, "You" includes any entity that

2. License Grants and Conditions
|
||||
--------------------------------
|
||||
|
||||
2.1. Grants
|
||||
|
||||
Each Contributor hereby grants You a world-wide, royalty-free,
|
||||
non-exclusive license:
|
||||
|
||||
(a) under intellectual property rights (other than patent or trademark)
|
||||
Licensable by such Contributor to use, reproduce, make available,
|
||||
modify, display, perform, distribute, and otherwise exploit its
|
||||
Contributions, either on an unmodified basis, with Modifications, or
|
||||
as part of a Larger Work; and
|
||||
|
||||
(b) under Patent Claims of such Contributor to make, use, sell, offer
|
||||
for sale, have made, import, and otherwise transfer either its
|
||||
Contributions or its Contributor Version.
|
||||
|
||||
2.2. Effective Date
|
||||
|
||||
The licenses granted in Section 2.1 with respect to any Contribution
|
||||
become effective for each Contribution on the date the Contributor first
|
||||
distributes such Contribution.
|
||||
|
||||
2.3. Limitations on Grant Scope
|
||||
|
||||
The licenses granted in this Section 2 are the only rights granted under
|
||||
this License. No additional rights or licenses will be implied from the
|
||||
distribution or licensing of Covered Software under this License.
|
||||
Notwithstanding Section 2.1(b) above, no patent license is granted by a
|
||||
Contributor:
|
||||
|
||||
(a) for any code that a Contributor has removed from Covered Software;
|
||||
or
|
||||
|
||||
(b) for infringements caused by: (i) Your and any other third party's
|
||||
modifications of Covered Software, or (ii) the combination of its
|
||||
Contributions with other software (except as part of its Contributor
|
||||
Version); or
|
||||
|
||||
(c) under Patent Claims infringed by Covered Software in the absence of
|
||||
its Contributions.
|
||||
|
||||
This License does not grant any rights in the trademarks, service marks,
|
||||
or logos of any Contributor (except as may be necessary to comply with
|
||||
the notice requirements in Section 3.4).
|
||||
|
||||
2.4. Subsequent Licenses
|
||||
|
||||
No Contributor makes additional grants as a result of Your choice to
|
||||
distribute the Covered Software under a subsequent version of this
|
||||
License (see Section 10.2) or under the terms of a Secondary License (if
|
||||
permitted under the terms of Section 3.3).
|
||||
|
||||
2.5. Representation
|
||||
|
||||
Each Contributor represents that the Contributor believes its
|
||||
Contributions are its original creation(s) or it has sufficient rights
|
||||
to grant the rights to its Contributions conveyed by this License.
|
||||
|
||||
2.6. Fair Use
|
||||
|
||||
This License is not intended to limit any rights You have under
|
||||
applicable copyright doctrines of fair use, fair dealing, or other
|
||||
equivalents.
|
||||
|
||||
2.7. Conditions
|
||||
|
||||
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
|
||||
in Section 2.1.
|
||||
|
||||
3. Responsibilities
|
||||
-------------------
|
||||
|
||||
3.1. Distribution of Source Form
|
||||
|
||||
All distribution of Covered Software in Source Code Form, including any
|
||||
Modifications that You create or to which You contribute, must be under
|
||||
the terms of this License. You must inform recipients that the Source
|
||||
Code Form of the Covered Software is governed by the terms of this
|
||||
License, and how they can obtain a copy of this License. You may not
|
||||
attempt to alter or restrict the recipients' rights in the Source Code
|
||||
Form.
|
||||
|
||||
3.2. Distribution of Executable Form
|
||||
|
||||
If You distribute Covered Software in Executable Form then:
|
||||
|
||||
(a) such Covered Software must also be made available in Source Code
|
||||
Form, as described in Section 3.1, and You must inform recipients of
|
||||
the Executable Form how they can obtain a copy of such Source Code
|
||||
Form by reasonable means in a timely manner, at a charge no more
|
||||
than the cost of distribution to the recipient; and
|
||||
|
||||
(b) You may distribute such Executable Form under the terms of this
|
||||
License, or sublicense it under different terms, provided that the
|
||||
license for the Executable Form does not attempt to limit or alter
|
||||
the recipients' rights in the Source Code Form under this License.
|
||||
|
||||
3.3. Distribution of a Larger Work
|
||||
|
||||
You may create and distribute a Larger Work under terms of Your choice,
|
||||
provided that You also comply with the requirements of this License for
|
||||
the Covered Software. If the Larger Work is a combination of Covered
|
||||
Software with a work governed by one or more Secondary Licenses, and the
|
||||
Covered Software is not Incompatible With Secondary Licenses, this
|
||||
License permits You to additionally distribute such Covered Software
|
||||
under the terms of such Secondary License(s), so that the recipient of
|
||||
the Larger Work may, at their option, further distribute the Covered
|
||||
Software under the terms of either this License or such Secondary
|
||||
License(s).
|
||||
|
||||
3.4. Notices
|
||||
|
||||
You may not remove or alter the substance of any license notices
|
||||
(including copyright notices, patent notices, disclaimers of warranty,
|
||||
or limitations of liability) contained within the Source Code Form of
|
||||
the Covered Software, except that You may alter any license notices to
|
||||
the extent required to remedy known factual inaccuracies.
|
||||
|
||||
3.5. Application of Additional Terms
|
||||
|
||||
You may choose to offer, and to charge a fee for, warranty, support,
|
||||
indemnity or liability obligations to one or more recipients of Covered
|
||||
Software. However, You may do so only on Your own behalf, and not on
|
||||
behalf of any Contributor. You must make it absolutely clear that any
|
||||
such warranty, support, indemnity, or liability obligation is offered by
|
||||
You alone, and You hereby agree to indemnify every Contributor for any
|
||||
liability incurred by such Contributor as a result of warranty, support,
|
||||
indemnity or liability terms You offer. You may include additional
|
||||
disclaimers of warranty and limitations of liability specific to any
|
||||
jurisdiction.
|
||||
|
||||
4. Inability to Comply Due to Statute or Regulation
|
||||
---------------------------------------------------
|
||||
|
||||
If it is impossible for You to comply with any of the terms of this
|
||||
License with respect to some or all of the Covered Software due to
|
||||
statute, judicial order, or regulation then You must: (a) comply with
|
||||
the terms of this License to the maximum extent possible; and (b)
|
||||
describe the limitations and the code they affect. Such description must
|
||||
be placed in a text file included with all distributions of the Covered
|
||||
Software under this License. Except to the extent prohibited by statute
|
||||
or regulation, such description must be sufficiently detailed for a
|
||||
recipient of ordinary skill to be able to understand it.
|
||||
|
||||
5. Termination
|
||||
--------------
|
||||
|
||||
5.1. The rights granted under this License will terminate automatically
|
||||
if You fail to comply with any of its terms. However, if You become
|
||||
compliant, then the rights granted under this License from a particular
|
||||
Contributor are reinstated (a) provisionally, unless and until such
|
||||
Contributor explicitly and finally terminates Your grants, and (b) on an
|
||||
ongoing basis, if such Contributor fails to notify You of the
|
||||
non-compliance by some reasonable means prior to 60 days after You have
|
||||
come back into compliance. Moreover, Your grants from a particular
|
||||
Contributor are reinstated on an ongoing basis if such Contributor
|
||||
notifies You of the non-compliance by some reasonable means, this is the
|
||||
first time You have received notice of non-compliance with this License
|
||||
from such Contributor, and You become compliant prior to 30 days after
|
||||
Your receipt of the notice.
|
||||
|
||||
5.2. If You initiate litigation against any entity by asserting a patent
|
||||
infringement claim (excluding declaratory judgment actions,
|
||||
counter-claims, and cross-claims) alleging that a Contributor Version
|
||||
directly or indirectly infringes any patent, then the rights granted to
|
||||
You by any and all Contributors for the Covered Software under Section
|
||||
2.1 of this License shall terminate.
|
||||
|
||||
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
|
||||
end user license agreements (excluding distributors and resellers) which
|
||||
have been validly granted by You or Your distributors under this License
|
||||
prior to termination shall survive termination.
|
||||

* 6. Disclaimer of Warranty *
|
||||
* ------------------------- *
|
||||
* *
|
||||
* Covered Software is provided under this License on an "as is" *
|
||||
* basis, without warranty of any kind, either expressed, implied, or *
|
||||
* statutory, including, without limitation, warranties that the *
|
||||
* Covered Software is free of defects, merchantable, fit for a *

************************************************************************
|
||||
|

8. Litigation
|
||||
-------------
|
||||
|
||||
Any litigation relating to this License may be brought only in the
|
||||
courts of a jurisdiction where the defendant maintains its principal
|
||||
place of business and such litigation shall be governed by laws of that
|
||||
jurisdiction, without reference to its conflict-of-law provisions.
|
||||
Nothing in this Section shall prevent a party's ability to bring
|
||||
cross-claims or counter-claims.
|
||||
|
||||
9. Miscellaneous
|
||||
----------------
|
||||
|
||||
This License represents the complete agreement concerning the subject
|
||||
matter hereof. If any provision of this License is held to be
|
||||
unenforceable, such provision shall be reformed only to the extent
|
||||
necessary to make it enforceable. Any law or regulation which provides
|
||||
that the language of a contract shall be construed against the drafter
|
||||
shall not be used to construe this License against a Contributor.
|
||||
|
||||
10. Versions of the License
|
||||
---------------------------
|
||||
|
||||
10.1. New Versions
|
||||

|
||||
create a new license for such software, you may create and use a
|
||||
modified version of this License if you rename the license and remove
|
||||
any references to the name of the license steward (except to note that
|
||||
such modified license differs from this License).
|
||||
|
||||
10.4. Distributing Source Code Form that is Incompatible With Secondary
|
||||

|
||||
|
||||
---------------------------------------
|
||||
|
||||
## Installation
|
||||
Simple install the package to your [$GOPATH](https://github.com/golang/go/wiki/GOPATH "GOPATH") with the [go tool](https://golang.org/cmd/go/ "go command") from shell:
|
||||
```bash
|
||||
$ go get -u github.com/go-sql-driver/mysql
|
||||
```
|
||||
Make sure [Git is installed](https://git-scm.com/downloads) on your machine and in your system's `PATH`.
|
||||
|
||||
## Usage
|
||||
_Go MySQL Driver_ is an implementation of Go's `database/sql/driver` interface. You only need to import the driver and can use the full [`database/sql`](https://golang.org/pkg/database/sql/) API then.
|
||||
|
||||
Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name) as `dataSourceName`:
|
||||
```go
|
||||
import "database/sql"
|
||||
import _ "github.com/go-sql-driver/mysql"
|
||||
|
||||
db, err := sql.Open("mysql", "user:password@/dbname")
|
||||
```
|
||||
|
||||
[Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples").
|
||||
|
||||
|
||||
### DSN (Data Source Name)
|
||||
|
||||
The Data Source Name has a common format, like e.g. [PEAR DB](http://pear.php.net/manual/en/package.database.db.intro-dsn.php) uses it, but without type-prefix (optional parts marked by squared brackets):
|
||||
```
|
||||
[username[:password]@][protocol[(address)]]/dbname[?param1=value1&...¶mN=valueN]
|
||||
```
|
||||
|
||||
A DSN in its fullest form:
|
||||
```
|
||||
username:password@protocol(address)/dbname?param=value
|
||||
```
|
||||
|
||||
Except for the databasename, all values are optional. So the minimal DSN is:
|
||||
```
|
||||
/dbname
|
||||
```
|
||||
|
||||
If you do not want to preselect a database, leave `dbname` empty:
|
||||
```
|
||||
/
|
||||
```
|
||||
This has the same effect as an empty DSN string:
|
||||
```
|
||||
|
||||
```
|
||||
|
||||
Alternatively, [Config.FormatDSN](https://godoc.org/github.com/go-sql-driver/mysql#Config.FormatDSN) can be used to create a DSN string by filling a struct.
|
||||
|
||||
#### Password
|
||||
Passwords can consist of any character. Escaping is **not** necessary.
|
||||
|
||||
#### Protocol
|
||||
See [net.Dial](https://golang.org/pkg/net/#Dial) for more information which networks are available.
|
||||
In general you should use an Unix domain socket if available and TCP otherwise for best performance.
|
||||
|
||||
#### Address
|
||||
For TCP and UDP networks, addresses have the form `host[:port]`.
|
||||
If `port` is omitted, the default port will be used.
|
||||
If `host` is a literal IPv6 address, it must be enclosed in square brackets.
|
||||
The functions [net.JoinHostPort](https://golang.org/pkg/net/#JoinHostPort) and [net.SplitHostPort](https://golang.org/pkg/net/#SplitHostPort) manipulate addresses in this form.
|
||||
|
||||
For Unix domain sockets the address is the absolute path to the MySQL-Server-socket, e.g. `/var/run/mysqld/mysqld.sock` or `/tmp/mysql.sock`.
|
||||
|
||||
#### Parameters
|
||||
*Parameters are case-sensitive!*
|
||||
|
||||
Notice that any of `true`, `TRUE`, `True` or `1` is accepted to stand for a true boolean value. Not surprisingly, false can be specified as any of: `false`, `FALSE`, `False` or `0`.
|
||||
|
||||
##### `allowAllFiles`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
`allowAllFiles=true` disables the file Whitelist for `LOAD DATA LOCAL INFILE` and allows *all* files.
|
||||
[*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)
|
||||
|
||||
##### `allowCleartextPasswords`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
`allowCleartextPasswords=true` allows using the [cleartext client side plugin](http://dev.mysql.com/doc/en/cleartext-authentication-plugin.html) if required by an account, such as one defined with the [PAM authentication plugin](http://dev.mysql.com/doc/en/pam-authentication-plugin.html). Sending passwords in clear text may be a security problem in some configurations. To avoid problems if there is any possibility that the password would be intercepted, clients should connect to MySQL Server using a method that protects the password. Possibilities include [TLS / SSL](#tls), IPsec, or a private network.
|
||||
|
||||
##### `allowNativePasswords`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: true
|
||||
```
|
||||
`allowNativePasswords=false` disallows the usage of MySQL native password method.
|
||||
|
||||
##### `allowOldPasswords`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
`allowOldPasswords=true` allows the usage of the insecure old password method. This should be avoided, but is necessary in some cases. See also [the old_passwords wiki page](https://github.com/go-sql-driver/mysql/wiki/old_passwords).
|
||||
|
||||
##### `charset`
|
||||
|
||||
```
|
||||
Type: string
|
||||
Valid Values: <name>
|
||||
Default: none
|
||||
```
|
||||
|
||||
Sets the charset used for client-server interaction (`"SET NAMES <value>"`). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables for example support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`).
|
||||
|
||||
Usage of the `charset` parameter is discouraged because it issues additional queries to the server.
|
||||
Unless you need the fallback behavior, please use `collation` instead.
|
||||
|
||||
##### `checkConnLiveness`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: true
|
||||
```
|
||||
|
||||
On supported platforms connections retrieved from the connection pool are checked for liveness before using them. If the check fails, the respective connection is marked as bad and the query retried with another connection.
|
||||
`checkConnLiveness=false` disables this liveness check of connections.
|
||||
|
||||
##### `collation`
|
||||
|
||||
```
|
||||
Type: string
|
||||
Valid Values: <name>
|
||||
Default: utf8mb4_general_ci
|
||||
```
|
||||
|
||||
Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail.
|
||||
|
||||
A list of valid charsets for a server is retrievable with `SHOW COLLATION`.
|
||||
|
||||
The default collation (`utf8mb4_general_ci`) is supported from MySQL 5.5. You should use an older collation (e.g. `utf8_general_ci`) for older MySQL.
|
||||
|
||||
Collations for charset "ucs2", "utf16", "utf16le", and "utf32" can not be used ([ref](https://dev.mysql.com/doc/refman/5.7/en/charset-connection.html#charset-connection-impermissible-client-charset)).
|
||||
|
||||
|
||||
##### `clientFoundRows`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
`clientFoundRows=true` causes an UPDATE to return the number of matching rows instead of the number of rows changed.
|
||||
|
||||
##### `columnsWithAlias`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
When `columnsWithAlias` is true, calls to `sql.Rows.Columns()` will return the table alias and the column name separated by a dot. For example:
|
||||
|
||||
```
|
||||
SELECT u.id FROM users as u
|
||||
```
|
||||
|
||||
will return `u.id` instead of just `id` if `columnsWithAlias=true`.
|
||||
|
||||
##### `interpolateParams`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
If `interpolateParams` is true, placeholders (`?`) in calls to `db.Query()` and `db.Exec()` are interpolated into a single query string with given parameters. This reduces the number of roundtrips, since the driver has to prepare a statement, execute it with given parameters and close the statement again with `interpolateParams=false`.
|
||||
|
||||
*This can not be used together with the multibyte encodings BIG5, CP932, GB2312, GBK or SJIS. These are blacklisted as they may [introduce a SQL injection vulnerability](http://stackoverflow.com/a/12118602/3430118)!*
|
||||
|
||||
##### `loc`
|
||||
|
||||
```
|
||||
Type: string
|
||||
Valid Values: <escaped name>
|
||||
Default: UTC
|
||||
```
|
||||
|
||||
Sets the location for time.Time values (when using `parseTime=true`). *"Local"* sets the system's location. See [time.LoadLocation](https://golang.org/pkg/time/#LoadLocation) for details.
|
||||
|
||||
Note that this sets the location for time.Time values but does not change MySQL's [time_zone setting](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html). For that see the [time_zone system variable](#system-variables), which can also be set as a DSN parameter.
|
||||
|
||||
Please keep in mind, that param values must be [url.QueryEscape](https://golang.org/pkg/net/url/#QueryEscape)'ed. Alternatively you can manually replace the `/` with `%2F`. For example `US/Pacific` would be `loc=US%2FPacific`.
|
||||
|
||||
##### `maxAllowedPacket`
|
||||
```
|
||||
Type: decimal number
|
||||
Default: 4194304
|
||||
```
|
||||
|
||||
Max packet size allowed in bytes. The default value is 4 MiB and should be adjusted to match the server settings. `maxAllowedPacket=0` can be used to automatically fetch the `max_allowed_packet` variable from server *on every connection*.
|
||||
|
||||
##### `multiStatements`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
Allow multiple statements in one query. While this allows batch queries, it also greatly increases the risk of SQL injections. Only the result of the first query is returned, all other results are silently discarded.
|
||||
|
||||
When `multiStatements` is used, `?` parameters must only be used in the first statement.
|
||||
|
||||
##### `parseTime`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
`parseTime=true` changes the output type of `DATE` and `DATETIME` values to `time.Time` instead of `[]byte` / `string`
|
||||
The date or datetime like `0000-00-00 00:00:00` is converted into zero value of `time.Time`.
|
||||
|
||||
|
||||
##### `readTimeout`
|
||||
|
||||
```
|
||||
Type: duration
|
||||
Default: 0
|
||||
```
|
||||
|
||||
I/O read timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
|
||||
|
||||
##### `rejectReadOnly`
|
||||
|
||||
```
|
||||
Type: bool
|
||||
Valid Values: true, false
|
||||
Default: false
|
||||
```
|
||||
|
||||
|
||||
`rejectReadOnly=true` causes the driver to reject read-only connections. This
|
||||
is for a possible race condition during an automatic failover, where the mysql
|
||||
client gets connected to a read-only replica after the failover.
|
||||
|
||||
Note that this should be a fairly rare case, as an automatic failover normally
|
||||
happens when the primary is down, and the race condition shouldn't happen
|
||||
unless it comes back up online as soon as the failover is kicked off. On the
|
||||
other hand, when this happens, a MySQL application can get stuck on a
|
||||
read-only connection until restarted. It is however fairly easy to reproduce,
|
||||
for example, using a manual failover on AWS Aurora's MySQL-compatible cluster.
|
||||
|
||||
If you are not relying on read-only transactions to reject writes that aren't
|
||||
supposed to happen, setting this on some MySQL providers (such as AWS Aurora)
|
||||
is safer for failovers.
|
||||
|
||||
Note that ERROR 1290 can be returned for a `read-only` server and this option will
|
||||
cause a retry for that error. However the same error number is used for some
|
||||
other cases. You should ensure your application will never cause an ERROR 1290
|
||||
except for `read-only` mode when enabling this option.
|
||||
|
||||
|
||||
##### `serverPubKey`
|
||||
|
||||
```
|
||||
Type: string
|
||||
Valid Values: <name>
|
||||
Default: none
|
||||
```
|
||||
|
||||
Server public keys can be registered with [`mysql.RegisterServerPubKey`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterServerPubKey), which can then be used by the assigned name in the DSN.
|
||||
Public keys are used to transmit encrypted data, e.g. for authentication.
|
||||
If the server's public key is known, it should be set manually to avoid expensive and potentially insecure transmissions of the public key from the server to the client each time it is required.
|
||||
|
||||
|
||||
##### `timeout`
|
||||
|
||||
```
|
||||
Type: duration
|
||||
Default: OS default
|
||||
```
|
||||
|
||||
Timeout for establishing connections, aka dial timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
|
||||
|
||||
|
||||
##### `tls`
|
||||
|
||||
```
|
||||
Type: bool / string
|
||||
Valid Values: true, false, skip-verify, preferred, <name>
|
||||
Default: false
|
||||
```
|
||||
|
||||
`tls=true` enables TLS / SSL encrypted connection to the server. Use `skip-verify` if you want to use a self-signed or invalid certificate (server side) or use `preferred` to use TLS only when advertised by the server. This is similar to `skip-verify`, but additionally allows a fallback to a connection which is not encrypted. Neither `skip-verify` nor `preferred` add any reliable security. You can use a custom TLS config after registering it with [`mysql.RegisterTLSConfig`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig).
|
||||
|
||||
|
||||
##### `writeTimeout`
|
||||
|
||||
```
|
||||
Type: duration
|
||||
Default: 0
|
||||
```
|
||||
|
||||
I/O write timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
|
||||
|
||||
|
||||
##### System Variables
|
||||
|
||||
Any other parameters are interpreted as system variables:
|
||||
* `<boolean_var>=<value>`: `SET <boolean_var>=<value>`
|
||||
* `<enum_var>=<value>`: `SET <enum_var>=<value>`
|
||||
* `<string_var>=%27<value>%27`: `SET <string_var>='<value>'`
|
||||
|
||||
Rules:
|
||||
* The values for string variables must be quoted with `'`.
|
||||
* The values must also be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed!
|
||||
(which implies values of string variables must be wrapped with `%27`).
|
||||
|
||||
Examples:
|
||||
* `autocommit=1`: `SET autocommit=1`
|
||||
* [`time_zone=%27Europe%2FParis%27`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `SET time_zone='Europe/Paris'`
|
||||
* [`tx_isolation=%27REPEATABLE-READ%27`](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation): `SET tx_isolation='REPEATABLE-READ'`
|
||||
|
||||
|
||||
#### Examples
|
||||
```
|
||||
user@unix(/path/to/socket)/dbname
|
||||
```
|
||||
|
||||
```
|
||||
root:pw@unix(/tmp/mysql.sock)/myDatabase?loc=Local
|
||||
```
|
||||
|
||||
```
|
||||
user:password@tcp(localhost:5555)/dbname?tls=skip-verify&autocommit=true
|
||||
```
|
||||
|
||||
Treat warnings as errors by setting the system variable [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html):
|
||||
```
|
||||
user:password@/dbname?sql_mode=TRADITIONAL
|
||||
```
|
||||
|
||||
TCP via IPv6:
|
||||
```
|
||||
user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?timeout=90s&collation=utf8mb4_unicode_ci
|
||||
```
|
||||
|
||||
TCP on a remote host, e.g. Amazon RDS:
|
||||
```
|
||||
id:password@tcp(your-amazonaws-uri.com:3306)/dbname
|
||||
```
|
||||
|
||||
Google Cloud SQL on App Engine:
|
||||
```
|
||||
user:password@unix(/cloudsql/project-id:region-name:instance-name)/dbname
|
||||
```
|
||||
|
||||
TCP using default port (3306) on localhost:
|
||||
```
|
||||
user:password@tcp/dbname?charset=utf8mb4,utf8&sys_var=esc%40ped
|
||||
```
|
||||
|
||||
Use the default protocol (tcp) and host (localhost:3306):
|
||||
```
|
||||
user:password@/dbname
|
||||
```
|
||||
|
||||
No Database preselected:
|
||||
```
|
||||
user:password@/
|
||||
```
|
||||
|
||||
|
||||
### Connection pool and timeouts
|
||||
The connection pool is managed by Go's database/sql package. For details on how to configure the size of the pool and how long connections stay in the pool see `*DB.SetMaxOpenConns`, `*DB.SetMaxIdleConns`, and `*DB.SetConnMaxLifetime` in the [database/sql documentation](https://golang.org/pkg/database/sql/). The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively.
|
||||
|
||||
## `ColumnType` Support
|
||||
This driver supports the [`ColumnType` interface](https://golang.org/pkg/database/sql/#ColumnType) introduced in Go 1.8, with the exception of [`ColumnType.Length()`](https://golang.org/pkg/database/sql/#ColumnType.Length), which is currently not supported.
|
||||
|
||||
## `context.Context` Support
|
||||
Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts.
|
||||
See [context support in the database/sql package](https://golang.org/doc/go1.8#database_sql) for more details.
|
||||
|
||||
|
||||
### `LOAD DATA LOCAL INFILE` support
|
||||
For this feature you need direct access to the package. Therefore you must change the import path (no `_`):
|
||||
```go
|
||||
import "github.com/go-sql-driver/mysql"
|
||||
```
|
||||
|
||||
Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` ([*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)).
|
||||
|
||||
To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::<name>` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore.
|
||||
|
||||
See the [godoc of Go-MySQL-Driver](https://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") for details.
|
||||
|
||||
|
||||
### `time.Time` support
|
||||
The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your program.
|
||||
|
||||
However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical equivalent in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
|
||||
|
||||
**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes).
|
||||
|
||||
Alternatively you can use the [`NullTime`](https://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`.
|
||||
|
||||
|
||||
### Unicode support
|
||||
Since version 1.5 Go-MySQL-Driver automatically uses the collation ` utf8mb4_general_ci` by default.
|
||||
|
||||
Other collations / charsets can be set using the [`collation`](#collation) DSN parameter.
|
||||
|
||||
Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default.
|
||||
|
||||
See http://dev.mysql.com/doc/refman/8.0/en/charset-unicode.html for more details on MySQL's Unicode support.
|
||||
|
||||
## Testing / Development
|
||||
To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.
|
||||
|
||||
Go-MySQL-Driver is not feature-complete yet. Your help is very appreciated.

||||

|
||||
|
||||
Package `gorilla/mux` implements a request router and dispatcher for matching incoming requests to
|
||||
their respective handler.
|
||||
|
||||
The name mux stands for "HTTP request multiplexer". Like the standard `http.ServeMux`, `mux.Router` matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are:
|
||||
|
||||
* It implements the `http.Handler` interface so it is compatible with the standard `http.ServeMux`.
|
||||
* Requests can be matched based on URL host, path, path prefix, schemes, header and query values, HTTP methods or using custom matchers.
|
||||
* URL hosts, paths and query values can have variables with an optional regular expression.
|
||||
* Registered URLs can be built, or "reversed", which helps maintaining references to resources.
|
||||
* Routes can be used as subrouters: nested routes are only tested if the parent route matches. This is useful to define groups of routes that share common conditions like a host, a path prefix or other repeated attributes. As a bonus, this optimizes request matching.

|
||||
## Install
|
||||
|
||||
With a [correctly configured](https://golang.org/doc/install#testing) Go toolchain:
|
||||
|
||||
```sh
|
||||
go get -u github.com/gorilla/mux
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
Let's start registering a couple of URL paths and handlers:
|
||||
|
||||
```go
|
||||
func main() {
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/", HomeHandler)
|
||||
r.HandleFunc("/products", ProductsHandler)
|
||||
r.HandleFunc("/articles", ArticlesHandler)
|
||||
http.Handle("/", r)
|
||||
}
|
||||
```
|
||||
|
||||
Here we register three routes mapping URL paths to handlers. This is equivalent to how `http.HandleFunc()` works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (`http.ResponseWriter`, `*http.Request`) as parameters.
|
||||
|
||||
Paths can have variables. They are defined using the format `{name}` or `{name:pattern}`. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example:
|
||||
|
||||
```go
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/products/{key}", ProductHandler)
|
||||
r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
|
||||
r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
|
||||
```
|
||||
|
||||
The names are used to create a map of route variables which can be retrieved calling `mux.Vars()`:
|
||||
|
||||
```go
|
||||
func ArticlesCategoryHandler(w http.ResponseWriter, r *http.Request) {
|
||||
vars := mux.Vars(r)
|
||||
w.WriteHeader(http.StatusOK)
|
||||
fmt.Fprintf(w, "Category: %v\n", vars["category"])
|
||||
}
|
||||
```
|
||||
|
||||
And this is all you need to know about the basic usage. More advanced options are explained below.
|
||||
|
||||
### Matching Routes
|
||||
|
||||
Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables:
|
||||
|
||||
```go
|
||||
r := mux.NewRouter()
|
||||
// Only matches if domain is "www.example.com".
|
||||
r.Host("www.example.com")
|
||||
// Matches a dynamic subdomain.
|
||||
r.Host("{subdomain:[a-z]+}.example.com")
|
||||
```
|
||||
|
||||
There are several other matchers that can be added. To match path prefixes:
|
||||
|
||||
```go
|
||||
r.PathPrefix("/products/")
|
||||
```
|
||||
|
||||
...or HTTP methods:
|
||||
|
||||
```go
|
||||
r.Methods("GET", "POST")
|
||||
```
|
||||
|
||||
...or URL schemes:
|
||||
|
||||
```go
|
||||
r.Schemes("https")
|
||||
```
|
||||
|
||||
...or header values:
|
||||
|
||||
```go
|
||||
r.Headers("X-Requested-With", "XMLHttpRequest")
|
||||
```
|
||||
|
||||
...or query values:
|
||||
|
||||
```go
|
||||
r.Queries("key", "value")
|
||||
```
|
||||
|
||||
...or to use a custom matcher function:
|
||||
|
||||
```go
|
||||
r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
|
||||
return r.ProtoMajor == 0
|
||||
})
|
||||
```
|
||||
|
||||
...and finally, it is possible to combine several matchers in a single route:
|
||||
|
||||
```go
|
||||
r.HandleFunc("/products", ProductsHandler).
|
||||
Host("www.example.com").
|
||||
Methods("GET").
|
||||
Schemes("http")
|
||||
```
|
||||
|
||||
Routes are tested in the order they were added to the router. If two routes match, the first one wins:
|
||||
|
||||
```go
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/specific", specificHandler)
|
||||
r.PathPrefix("/").Handler(catchAllHandler)
|
||||
```
|
||||
|
||||
Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting".
|
||||
|
||||
For example, let's say we have several URLs that should only match when the host is `www.example.com`. Create a route for that host and get a "subrouter" from it:
|
||||
|
||||
```go
|
||||
r := mux.NewRouter()
|
||||
s := r.Host("www.example.com").Subrouter()
|
||||
```
|
||||
|
||||
Then register routes in the subrouter:
|
||||
|
||||
```go
|
||||
s.HandleFunc("/products/", ProductsHandler)
|
||||
s.HandleFunc("/products/{key}", ProductHandler)
|
||||
s.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
|
||||
```
|
||||
|
||||
The three URL paths we registered above will only be tested if the domain is `www.example.com`, because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route.
|
||||
|
||||
Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter.
|
||||
|
||||
There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths:
|
||||
|
||||
```go
|
||||
r := mux.NewRouter()
|
||||
s := r.PathPrefix("/products").Subrouter()
|
||||
// "/products/"
|
||||
s.HandleFunc("/", ProductsHandler)
|
||||
// "/products/{key}/"
|
||||
s.HandleFunc("/{key}/", ProductHandler)
|
||||
// "/products/{key}/details"
|
||||
s.HandleFunc("/{key}/details", ProductDetailsHandler)
|
||||
```
|
||||
|
||||
|
||||
### Static Files
|
||||
|
||||
Note that the path provided to `PathPrefix()` represents a "wildcard": calling
|
||||
`PathPrefix("/static/").Handler(...)` means that the handler will be passed any
|
||||
request that matches "/static/\*". This makes it easy to serve static files with mux:
|
||||
|
||||
```go
|
||||
func main() {
|
||||
var dir string
|
||||
|
||||
flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
|
||||
flag.Parse()
|
||||
r := mux.NewRouter()
|
||||
|
||||
// This will serve files under http://localhost:8000/static/<filename>
|
||||
r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
|
||||
|
||||
srv := &http.Server{
|
||||
Handler: r,
|
||||
Addr: "127.0.0.1:8000",
|
||||
// Good practice: enforce timeouts for servers you create!
|
||||
WriteTimeout: 15 * time.Second,
|
||||
ReadTimeout: 15 * time.Second,
|
||||
}
|
||||
|
||||
log.Fatal(srv.ListenAndServe())
|
||||
}
|
||||
```
|
||||
|
||||
### Serving Single Page Applications
|
||||
|
||||
Most of the time it makes sense to serve your SPA on a separate web server from your API,
|
||||
but sometimes it's desirable to serve them both from one place. It's possible to write a simple
|
||||
handler for serving your SPA (for use with React Router's [BrowserRouter](https://reacttraining.com/react-router/web/api/BrowserRouter) for example), and leverage
|
||||
mux's powerful routing for your API endpoints.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"encoding/json"
|
||||
"log"
|
||||
"net/http"
|
||||
"os"
|
||||
"path/filepath"
|
||||
"time"
|
||||
|
||||
"github.com/gorilla/mux"
|
||||
)
|
||||
|
||||
// spaHandler implements the http.Handler interface, so we can use it
|
||||
// to respond to HTTP requests. The path to the static directory and
|
||||
// path to the index file within that static directory are used to
|
||||
// serve the SPA in the given static directory.
|
||||
type spaHandler struct {
|
||||
staticPath string
|
||||
indexPath string
|
||||
}
|
||||
|
||||
// ServeHTTP inspects the URL path to locate a file within the static dir
|
||||
// on the SPA handler. If a file is found, it will be served. If not, the
|
||||
// file located at the index path on the SPA handler will be served. This
|
||||
// is suitable behavior for serving an SPA (single page application).
|
||||
func (h spaHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
|
||||
// get the absolute path to prevent directory traversal
|
||||
path, err := filepath.Abs(r.URL.Path)
|
||||
if err != nil {
|
||||
// if we failed to get the absolute path respond with a 400 bad request
|
||||
// and stop
|
||||
http.Error(w, err.Error(), http.StatusBadRequest)
|
||||
return
|
||||
}
|
||||
|
||||
// prepend the path with the path to the static directory
|
||||
path = filepath.Join(h.staticPath, path)
|
||||
|
||||
// check whether a file exists at the given path
|
||||
_, err = os.Stat(path)
|
||||
if os.IsNotExist(err) {
|
||||
// file does not exist, serve index.html
|
||||
http.ServeFile(w, r, filepath.Join(h.staticPath, h.indexPath))
|
||||
return
|
||||
} else if err != nil {
|
||||
// if we got an error (that wasn't that the file doesn't exist) stating the
|
||||
// file, return a 500 internal server error and stop
|
||||
http.Error(w, err.Error(), http.StatusInternalServerError)
|
||||
return
|
||||
}
|
||||
|
||||
// otherwise, use http.FileServer to serve the static dir
|
||||
http.FileServer(http.Dir(h.staticPath)).ServeHTTP(w, r)
|
||||
}
|
||||
|
||||
func main() {
|
||||
router := mux.NewRouter()
|
||||
|
||||
router.HandleFunc("/api/health", func(w http.ResponseWriter, r *http.Request) {
|
||||
// an example API handler
|
||||
json.NewEncoder(w).Encode(map[string]bool{"ok": true})
|
||||
})
|
||||
|
||||
spa := spaHandler{staticPath: "build", indexPath: "index.html"}
|
||||
router.PathPrefix("/").Handler(spa)
|
||||
|
||||
srv := &http.Server{
|
||||
Handler: router,
|
||||
Addr: "127.0.0.1:8000",
|
||||
// Good practice: enforce timeouts for servers you create!
|
||||
WriteTimeout: 15 * time.Second,
|
||||
ReadTimeout: 15 * time.Second,
|
||||
}
|
||||
|
||||
log.Fatal(srv.ListenAndServe())
|
||||
}
|
||||
```
|
||||
|
||||
### Registered URLs
|
||||
|
||||
Now let's see how to build registered URLs.
|
||||
|
||||
Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling `Name()` on a route. For example:
|
||||
|
||||
```go
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
|
||||
Name("article")
|
||||
```
|
||||
|
||||
To build a URL, get the route and call the `URL()` method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do:
|
||||
|
||||
```go
|
||||
url, err := r.Get("article").URL("category", "technology", "id", "42")
|
||||
```
|
||||
|
||||
...and the result will be a `url.URL` with the following path:
|
||||
|
||||
```
|
||||
"/articles/technology/42"
|
||||
```
|
||||
|
||||
This also works for host and query value variables:
|
||||
|
||||
```go
|
||||
r := mux.NewRouter()
|
||||
r.Host("{subdomain}.example.com").
|
||||
Path("/articles/{category}/{id:[0-9]+}").
|
||||
Queries("filter", "{filter}").
|
||||
HandlerFunc(ArticleHandler).
|
||||
Name("article")
|
||||
|
||||
// url.String() will be "http://news.example.com/articles/technology/42?filter=gorilla"
|
||||
url, err := r.Get("article").URL("subdomain", "news",
|
||||
"category", "technology",
|
||||
"id", "42",
|
||||
"filter", "gorilla")
|
||||
```
|
||||
|
||||
All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match.
|
||||
|
||||
Regex support also exists for matching Headers within a route. For example, we could do:
|
||||
|
||||
```go
|
||||
r.HeadersRegexp("Content-Type", "application/(text|json)")
|
||||
```
|
||||
|
||||
...and the route will match both requests with a Content-Type of `application/json` as well as `application/text`
|
||||
|
||||
There's also a way to build only the URL host or path for a route: use the methods `URLHost()` or `URLPath()` instead. For the previous route, we would do:
|
||||
|
||||
```go
|
||||
// "http://news.example.com/"
|
||||
host, err := r.Get("article").URLHost("subdomain", "news")
|
||||
|
||||
// "/articles/technology/42"
|
||||
path, err := r.Get("article").URLPath("category", "technology", "id", "42")
|
||||
```
|
||||
|
||||
And if you use subrouters, host and path defined separately can be built as well:
|
||||
|
||||
```go
|
||||
r := mux.NewRouter()
|
||||
s := r.Host("{subdomain}.example.com").Subrouter()
|
||||
s.Path("/articles/{category}/{id:[0-9]+}").
|
||||
HandlerFunc(ArticleHandler).
|
||||
Name("article")
|
||||
|
||||
// "http://news.example.com/articles/technology/42"
|
||||
url, err := r.Get("article").URL("subdomain", "news",
|
||||
"category", "technology",
|
||||
"id", "42")
|
||||
```
|
||||
|
||||
### Walking Routes
|
||||
|
||||
The `Walk` function on `mux.Router` can be used to visit all of the routes that are registered on a router. For example,
|
||||
the following prints all of the registered routes:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"net/http"
|
||||
"strings"
|
||||
|
||||
"github.com/gorilla/mux"
|
||||
)
|
||||
|
||||
func handler(w http.ResponseWriter, r *http.Request) {
|
||||
return
|
||||
}
|
||||
|
||||
func main() {
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/", handler)
|
||||
r.HandleFunc("/products", handler).Methods("POST")
|
||||
r.HandleFunc("/articles", handler).Methods("GET")
|
||||
r.HandleFunc("/articles/{id}", handler).Methods("GET", "PUT")
|
||||
r.HandleFunc("/authors", handler).Queries("surname", "{surname}")
|
||||
err := r.Walk(func(route *mux.Route, router *mux.Router, ancestors []*mux.Route) error {
|
||||
pathTemplate, err := route.GetPathTemplate()
|
||||
if err == nil {
|
||||
fmt.Println("ROUTE:", pathTemplate)
|
||||
}
|
||||
pathRegexp, err := route.GetPathRegexp()
|
||||
if err == nil {
|
||||
fmt.Println("Path regexp:", pathRegexp)
|
||||
}
|
||||
queriesTemplates, err := route.GetQueriesTemplates()
|
||||
if err == nil {
|
||||
fmt.Println("Queries templates:", strings.Join(queriesTemplates, ","))
|
||||
}
|
||||
queriesRegexps, err := route.GetQueriesRegexp()
|
||||
if err == nil {
|
||||
fmt.Println("Queries regexps:", strings.Join(queriesRegexps, ","))
|
||||
}
|
||||
methods, err := route.GetMethods()
|
||||
if err == nil {
|
||||
fmt.Println("Methods:", strings.Join(methods, ","))
|
||||
}
|
||||
fmt.Println()
|
||||
return nil
|
||||
})
|
||||
|
||||
if err != nil {
|
||||
fmt.Println(err)
|
||||
}
|
||||
|
||||
http.Handle("/", r)
|
||||
}
|
||||
```
|
||||
|
||||
### Graceful Shutdown
|
||||
|
||||
Go 1.8 introduced the ability to [gracefully shutdown](https://golang.org/doc/go1.8#http_shutdown) a `*http.Server`. Here's how to do that alongside `mux`:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"context"
|
||||
"flag"
|
||||
"log"
|
||||
"net/http"
|
||||
"os"
|
||||
"os/signal"
|
||||
"time"
|
||||
|
||||
"github.com/gorilla/mux"
|
||||
)
|
||||
|
||||
func main() {
|
||||
var wait time.Duration
|
||||
flag.DurationVar(&wait, "graceful-timeout", time.Second * 15, "the duration for which the server gracefully wait for existing connections to finish - e.g. 15s or 1m")
|
||||
flag.Parse()
|
||||
|
||||
r := mux.NewRouter()
|
||||
// Add your routes as needed
|
||||
|
||||
srv := &http.Server{
|
||||
Addr: "0.0.0.0:8080",
|
||||
// Good practice to set timeouts to avoid Slowloris attacks.
|
||||
WriteTimeout: time.Second * 15,
|
||||
ReadTimeout: time.Second * 15,
|
||||
IdleTimeout: time.Second * 60,
|
||||
Handler: r, // Pass our instance of gorilla/mux in.
|
||||
}
|
||||
|
||||
// Run our server in a goroutine so that it doesn't block.
|
||||
go func() {
|
||||
if err := srv.ListenAndServe(); err != nil {
|
||||
log.Println(err)
|
||||
}
|
||||
}()
|
||||
|
||||
c := make(chan os.Signal, 1)
|
||||
// We'll accept graceful shutdowns when quit via SIGINT (Ctrl+C)
|
||||
// SIGKILL, SIGQUIT or SIGTERM (Ctrl+/) will not be caught.
|
||||
signal.Notify(c, os.Interrupt)
|
||||
|
||||
// Block until we receive our signal.
|
||||
<-c
|
||||
|
||||
// Create a deadline to wait for.
|
||||
ctx, cancel := context.WithTimeout(context.Background(), wait)
|
||||
defer cancel()
|
||||
// Doesn't block if no connections, but will otherwise wait
|
||||
// until the timeout deadline.
|
||||
srv.Shutdown(ctx)
|
||||
// Optionally, you could run srv.Shutdown in a goroutine and block on
|
||||
// <-ctx.Done() if your application should wait for other services
|
||||
// to finalize based on context cancellation.
|
||||
log.Println("shutting down")
|
||||
os.Exit(0)
|
||||
}
|
||||
```
|
||||
|
||||
### Middleware
|
||||
|
||||
Mux supports the addition of middlewares to a [Router](https://godoc.org/github.com/gorilla/mux#Router), which are executed in the order they are added if a match is found, including its subrouters.
|
||||
Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or `ResponseWriter` hijacking.
|
||||
|
||||
Mux middlewares are defined using the de facto standard type:
|
||||
|
||||
```go
|
||||
type MiddlewareFunc func(http.Handler) http.Handler
|
||||
```
|
||||
|
||||
Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc. This takes advantage of closures being able access variables from the context where they are created, while retaining the signature enforced by the receivers.
|
||||
|
||||
A very basic middleware which logs the URI of the request being handled could be written as:
|
||||
|
||||
```go
|
||||
func loggingMiddleware(next http.Handler) http.Handler {
|
||||
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
|
||||
// Do stuff here
|
||||
log.Println(r.RequestURI)
|
||||
// Call the next handler, which can be another middleware in the chain, or the final handler.
|
||||
next.ServeHTTP(w, r)
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
Middlewares can be added to a router using `Router.Use()`:
|
||||
|
||||
```go
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/", handler)
|
||||
r.Use(loggingMiddleware)
|
||||
```
|
||||
|
||||
A more complex authentication middleware, which maps session token to users, could be written as:
|
||||
|
||||
```go
|
||||
// Define our struct
|
||||
type authenticationMiddleware struct {
|
||||
tokenUsers map[string]string
|
||||
}
|
||||
|
||||
// Initialize it somewhere
|
||||
func (amw *authenticationMiddleware) Populate() {
|
||||
amw.tokenUsers["00000000"] = "user0"
|
||||
amw.tokenUsers["aaaaaaaa"] = "userA"
|
||||
amw.tokenUsers["05f717e5"] = "randomUser"
|
||||
amw.tokenUsers["deadbeef"] = "user0"
|
||||
}
|
||||
|
||||
// Middleware function, which will be called for each request
|
||||
func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
|
||||
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
|
||||
token := r.Header.Get("X-Session-Token")
|
||||
|
||||
if user, found := amw.tokenUsers[token]; found {
|
||||
// We found the token in our map
|
||||
log.Printf("Authenticated user %s\n", user)
|
||||
// Pass down the request to the next middleware (or final handler)
|
||||
next.ServeHTTP(w, r)
|
||||
} else {
|
||||
// Write an error and stop the handler chain
|
||||
http.Error(w, "Forbidden", http.StatusForbidden)
|
||||
}
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
```go
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/", handler)
|
||||
|
||||
amw := authenticationMiddleware{}
|
||||
amw.Populate()
|
||||
|
||||
r.Use(amw.Middleware)
|
||||
```
|
||||
|
||||
Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to. Middlewares _should_ write to `ResponseWriter` if they _are_ going to terminate the request, and they _should not_ write to `ResponseWriter` if they _are not_ going to terminate it.
|
||||
|
||||
### Handling CORS Requests
|
||||
|
||||
[CORSMethodMiddleware](https://godoc.org/github.com/gorilla/mux#CORSMethodMiddleware) intends to make it easier to strictly set the `Access-Control-Allow-Methods` response header.
|
||||
|
||||
* You will still need to use your own CORS handler to set the other CORS headers such as `Access-Control-Allow-Origin`
|
||||
* The middleware will set the `Access-Control-Allow-Methods` header to all the method matchers (e.g. `r.Methods(http.MethodGet, http.MethodPut, http.MethodOptions)` -> `Access-Control-Allow-Methods: GET,PUT,OPTIONS`) on a route
|
||||
* If you do not specify any methods, then:
|
||||
> _Important_: there must be an `OPTIONS` method matcher for the middleware to set the headers.
|
||||
|
||||
Here is an example of using `CORSMethodMiddleware` along with a custom `OPTIONS` handler to set all the required CORS headers:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"net/http"
|
||||
"github.com/gorilla/mux"
|
||||
)
|
||||
|
||||
func main() {
|
||||
r := mux.NewRouter()
|
||||
|
||||
// IMPORTANT: you must specify an OPTIONS method matcher for the middleware to set CORS headers
|
||||
r.HandleFunc("/foo", fooHandler).Methods(http.MethodGet, http.MethodPut, http.MethodPatch, http.MethodOptions)
|
||||
r.Use(mux.CORSMethodMiddleware(r))
|
||||
|
||||
http.ListenAndServe(":8080", r)
|
||||
}
|
||||
|
||||
func fooHandler(w http.ResponseWriter, r *http.Request) {
|
||||
w.Header().Set("Access-Control-Allow-Origin", "*")
|
||||
if r.Method == http.MethodOptions {
|
||||
return
|
||||
}
|
||||
|
||||
w.Write([]byte("foo"))
|
||||
}
|
||||
```
|
||||
|
||||
And an request to `/foo` using something like:
|
||||
|
||||
```bash
|
||||
curl localhost:8080/foo -v
|
||||
```
|
||||
|
||||
Would look like:
|
||||
|
||||
```bash
|
||||
* Trying ::1...
|
||||
* TCP_NODELAY set
|
||||
* Connected to localhost (::1) port 8080 (#0)
|
||||
> GET /foo HTTP/1.1
|
||||
> Host: localhost:8080
|
||||
> User-Agent: curl/7.59.0
|
||||
> Accept: */*
|
||||
>
|
||||
< HTTP/1.1 200 OK
|
||||
< Access-Control-Allow-Methods: GET,PUT,PATCH,OPTIONS
|
||||
< Access-Control-Allow-Origin: *
|
||||
< Date: Fri, 28 Jun 2019 20:13:30 GMT
|
||||
< Content-Length: 3
|
||||
< Content-Type: text/plain; charset=utf-8
|
||||
<
|
||||
* Connection #0 to host localhost left intact
|
||||
foo
|
||||
```
|
||||
|
||||
### Testing Handlers
|
||||
|
||||
Testing handlers in a Go web application is straightforward, and _mux_ doesn't complicate this any further. Given two files: `endpoints.go` and `endpoints_test.go`, here's how we'd test an application using _mux_.
|
||||
|
||||
First, our simple HTTP handler:
|
||||
|
||||
```go
|
||||
// endpoints.go
|
||||
package main
|
||||
|
||||
func HealthCheckHandler(w http.ResponseWriter, r *http.Request) {
|
||||
// A very simple health check.
|
||||
w.Header().Set("Content-Type", "application/json")
|
||||
w.WriteHeader(http.StatusOK)
|
||||
|
||||
// In the future we could report back on the status of our DB, or our cache
|
||||
// (e.g. Redis) by performing a simple PING, and include them in the response.
|
||||
io.WriteString(w, `{"alive": true}`)
|

|

|
||||
func main() {
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/health", HealthCheckHandler)
|
||||
|
||||
log.Fatal(http.ListenAndServe("localhost:8080", r))
|
||||
}
|
||||
```
|
||||
|
||||
Our test code:
|
||||
|
||||
```go
|
||||
// endpoints_test.go
|
||||
package main
|
||||
|
||||
import (
|
||||
"net/http"
|
||||
"net/http/httptest"
|
||||
"testing"
|
||||
)
|
||||
|
||||
func TestHealthCheckHandler(t *testing.T) {
|
||||
// Create a request to pass to our handler. We don't have any query parameters for now, so we'll
|
||||
// pass 'nil' as the third parameter.
|
||||
req, err := http.NewRequest("GET", "/health", nil)
|
||||
if err != nil {
|
||||
t.Fatal(err)
|
||||
}
|
||||
|
||||
// We create a ResponseRecorder (which satisfies http.ResponseWriter) to record the response.
|
||||
rr := httptest.NewRecorder()
|
||||
handler := http.HandlerFunc(HealthCheckHandler)
|
||||
|
||||
// Our handlers satisfy http.Handler, so we can call their ServeHTTP method
|
||||
// directly and pass in our Request and ResponseRecorder.
|
||||
handler.ServeHTTP(rr, req)
|
||||
|
||||
// Check the status code is what we expect.
|
||||
if status := rr.Code; status != http.StatusOK {
|
||||
t.Errorf("handler returned wrong status code: got %v want %v",
|
||||
status, http.StatusOK)
|
||||
}
|
||||
|
||||
// Check the response body is what we expect.
|
||||
expected := `{"alive": true}`
|
||||
if rr.Body.String() != expected {
|
||||
t.Errorf("handler returned unexpected body: got %v want %v",
|
||||
rr.Body.String(), expected)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
In the case that our routes have [variables](#examples), we can pass those in the request. We could write
|
||||
[table-driven tests](https://dave.cheney.net/2013/06/09/writing-table-driven-tests-in-go) to test multiple
|
||||
possible route variables as needed.
|
||||
|
||||
```go
|
||||
// endpoints.go
|
||||
func main() {
|
||||
r := mux.NewRouter()
|
||||
// A route with a route variable:
|
||||
r.HandleFunc("/metrics/{type}", MetricsHandler)
|
||||
|
||||
log.Fatal(http.ListenAndServe("localhost:8080", r))
|
||||
}
|
||||
```
|
||||
|
||||
Our test file, with a table-driven test of `routeVariables`:
|
||||
|
||||
```go
|
||||
// endpoints_test.go
|
||||
func TestMetricsHandler(t *testing.T) {
|
||||
tt := []struct{
|
||||
routeVariable string
|
||||
shouldPass bool
|
||||
}{
|
||||
{"goroutines", true},
|
||||
{"heap", true},
|
||||
{"counters", true},
|
||||
{"queries", true},
|
||||
{"adhadaeqm3k", false},
|
||||
}
|
||||
|
||||
for _, tc := range tt {
|
||||
path := fmt.Sprintf("/metrics/%s", tc.routeVariable)
|
||||
req, err := http.NewRequest("GET", path, nil)
|
||||
if err != nil {
|
||||
t.Fatal(err)
|
||||
}
|
||||
|
||||
rr := httptest.NewRecorder()
|
||||
|
||||
// Need to create a router that we can pass the request through so that the vars will be added to the context
|
||||
router := mux.NewRouter()
|
||||
router.HandleFunc("/metrics/{type}", MetricsHandler)
|
||||
router.ServeHTTP(rr, req)
|
||||
|
||||
// In this case, our MetricsHandler returns a non-200 response
|
||||
// for a route variable it doesn't know about.
|
||||
if rr.Code == http.StatusOK && !tc.shouldPass {
|
||||
t.Errorf("handler should have failed on routeVariable %s: got %v want %v",
|
||||
tc.routeVariable, rr.Code, http.StatusOK)
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Full Example
|
||||
|
||||
Here's a complete, runnable example of a small `mux` based server:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"net/http"
|
||||
"log"
|
||||
"github.com/gorilla/mux"
|
||||
)
|
||||
|
||||
func YourHandler(w http.ResponseWriter, r *http.Request) {
|
||||
w.Write([]byte("Gorilla!\n"))
|
||||
}
|
||||
|
||||
func main() {
|
||||
r := mux.NewRouter()
|
||||
// Routes consist of a path and a handler function.
|
||||
r.HandleFunc("/", YourHandler)
|
||||
|
||||
// Bind to a port and pass our router in
|
||||
log.Fatal(http.ListenAndServe(":8000", r))
|
||||
}
|
||||
```

/*
|
||||
Package mux implements a request router and dispatcher.
|
||||
|
||||
The name mux stands for "HTTP request multiplexer". Like the standard
|
||||
http.ServeMux, mux.Router matches incoming requests against a list of
|
||||
registered routes and calls a handler for the route that matches the URL
|
||||
or other conditions. The main features are:
|
||||
|
||||
* Requests can be matched based on URL host, path, path prefix, schemes,
|
||||
header and query values, HTTP methods or using custom matchers.
|
||||
* URL hosts, paths and query values can have variables with an optional
|
||||
regular expression.
|
||||
* Registered URLs can be built, or "reversed", which helps maintaining
|
||||
references to resources.
|
||||
* Routes can be used as subrouters: nested routes are only tested if the
|
||||
parent route matches. This is useful to define groups of routes that
|
||||
share common conditions like a host, a path prefix or other repeated
|
||||
attributes. As a bonus, this optimizes request matching.
|
||||
* It implements the http.Handler interface so it is compatible with the
|
||||
standard http.ServeMux.
|
||||
|
||||
Let's start registering a couple of URL paths and handlers:
|
||||
|
||||
func main() {
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/", HomeHandler)
|
||||
r.HandleFunc("/products", ProductsHandler)
|
||||
r.HandleFunc("/articles", ArticlesHandler)
|
||||
http.Handle("/", r)
|
||||
}
|
||||
|
||||
Here we register three routes mapping URL paths to handlers. This is
|
||||
equivalent to how http.HandleFunc() works: if an incoming request URL matches
|
||||
one of the paths, the corresponding handler is called passing
|
||||
(http.ResponseWriter, *http.Request) as parameters.
|
||||
|
||||
Paths can have variables. They are defined using the format {name} or
|
||||
{name:pattern}. If a regular expression pattern is not defined, the matched
|
||||
variable will be anything until the next slash. For example:
|
||||
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/products/{key}", ProductHandler)
|
||||
r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
|
||||
r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
|
||||
|
||||
Groups can be used inside patterns, as long as they are non-capturing (?:re). For example:
|
||||
|
||||
r.HandleFunc("/articles/{category}/{sort:(?:asc|desc|new)}", ArticlesCategoryHandler)
|
||||
|
||||
The names are used to create a map of route variables which can be retrieved
|
||||
calling mux.Vars():
|
||||
|
||||
vars := mux.Vars(request)
|
||||
category := vars["category"]
|
||||
|
||||
Note that if any capturing groups are present, mux will panic() during parsing. To prevent
|
||||
this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to
|
||||
"/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably
|
||||
when capturing groups were present.
|
||||
|
||||
And this is all you need to know about the basic usage. More advanced options
|
||||
are explained below.
|
||||
|
||||
Routes can also be restricted to a domain or subdomain. Just define a host
|
||||
pattern to be matched. They can also have variables:
|
||||
|
||||
r := mux.NewRouter()
|
||||
// Only matches if domain is "www.example.com".
|
||||
r.Host("www.example.com")
|
||||
// Matches a dynamic subdomain.
|
||||
r.Host("{subdomain:[a-z]+}.domain.com")
|
||||
|
||||
There are several other matchers that can be added. To match path prefixes:
|
||||
|
||||
r.PathPrefix("/products/")
|
||||
|
||||
...or HTTP methods:
|
||||
|
||||
r.Methods("GET", "POST")
|
||||
|
||||
...or URL schemes:
|
||||
|
||||
r.Schemes("https")
|
||||
|
||||
...or header values:
|
||||
|
||||
r.Headers("X-Requested-With", "XMLHttpRequest")
|
||||
|
||||
...or query values:
|
||||
|
||||
r.Queries("key", "value")
|
||||
|
||||
...or to use a custom matcher function:
|
||||
|
||||
r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
|
||||
return r.ProtoMajor == 0
|
||||
})
|
||||
|
||||
...and finally, it is possible to combine several matchers in a single route:
|
||||
|
||||
r.HandleFunc("/products", ProductsHandler).
|
||||
Host("www.example.com").
|
||||
Methods("GET").
|
||||
Schemes("http")
|
||||
|
||||
Setting the same matching conditions again and again can be boring, so we have
|
||||
a way to group several routes that share the same requirements.
|
||||
We call it "subrouting".
|
||||
|
||||
For example, let's say we have several URLs that should only match when the
|
||||
host is "www.example.com". Create a route for that host and get a "subrouter"
|
||||
from it:
|
||||
|
||||
r := mux.NewRouter()
|
||||
s := r.Host("www.example.com").Subrouter()
|
||||
|
||||
Then register routes in the subrouter:
|
||||
|
||||
s.HandleFunc("/products/", ProductsHandler)
|
||||
s.HandleFunc("/products/{key}", ProductHandler)
|
||||
s.HandleFunc("/articles/{category}/{id:[0-9]+}"), ArticleHandler)
|
||||
|
||||
The three URL paths we registered above will only be tested if the domain is
|
||||
"www.example.com", because the subrouter is tested first. This is not
|
||||
only convenient, but also optimizes request matching. You can create
|
||||
subrouters combining any attribute matchers accepted by a route.
|
||||
|
||||
Subrouters can be used to create domain or path "namespaces": you define
|
||||
subrouters in a central place and then parts of the app can register its
|
||||
paths relatively to a given subrouter.
|
||||
|
||||
There's one more thing about subroutes. When a subrouter has a path prefix,
|
||||
the inner routes use it as base for their paths:
|
||||
|
||||
r := mux.NewRouter()
|
||||
s := r.PathPrefix("/products").Subrouter()
|
||||
// "/products/"
|
||||
s.HandleFunc("/", ProductsHandler)
|
||||
// "/products/{key}/"
|
||||
s.HandleFunc("/{key}/", ProductHandler)
|
||||
// "/products/{key}/details"
|
||||
s.HandleFunc("/{key}/details", ProductDetailsHandler)
|
||||
|
||||
Note that the path provided to PathPrefix() represents a "wildcard": calling
|
||||
PathPrefix("/static/").Handler(...) means that the handler will be passed any
|
||||
request that matches "/static/*". This makes it easy to serve static files with mux:
|
||||
|
||||
func main() {
|
||||
var dir string
|
||||
|
||||
flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
|
||||
flag.Parse()
|
||||
r := mux.NewRouter()
|
||||
|
||||
// This will serve files under http://localhost:8000/static/<filename>
|
||||
r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
|
||||
|
||||
srv := &http.Server{
|
||||
Handler: r,
|
||||
Addr: "127.0.0.1:8000",
|
||||
// Good practice: enforce timeouts for servers you create!
|
||||
WriteTimeout: 15 * time.Second,
|
||||
ReadTimeout: 15 * time.Second,
|
||||
}
|
||||
|
||||
log.Fatal(srv.ListenAndServe())
|
||||
}
|
||||
|
||||
Now let's see how to build registered URLs.
|
||||
|
||||
Routes can be named. All routes that define a name can have their URLs built,
|
||||
or "reversed". We define a name calling Name() on a route. For example:
|
||||
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
|
||||
Name("article")
|
||||
|
||||
To build a URL, get the route and call the URL() method, passing a sequence of
|
||||
key/value pairs for the route variables. For the previous route, we would do:
|
||||
|
||||
url, err := r.Get("article").URL("category", "technology", "id", "42")
|
||||
|
||||
...and the result will be a url.URL with the following path:
|
||||
|
||||
"/articles/technology/42"
|
||||
|
||||
This also works for host and query value variables:
|
||||
|
||||
r := mux.NewRouter()
|
||||
r.Host("{subdomain}.domain.com").
|
||||
Path("/articles/{category}/{id:[0-9]+}").
|
||||
Queries("filter", "{filter}").
|
||||
HandlerFunc(ArticleHandler).
|
||||
Name("article")
|
||||
|
||||
// url.String() will be "http://news.domain.com/articles/technology/42?filter=gorilla"
|
||||
url, err := r.Get("article").URL("subdomain", "news",
|
||||
"category", "technology",
|
||||
"id", "42",
|
||||
"filter", "gorilla")
|
||||
|
||||
All variables defined in the route are required, and their values must
|
||||
conform to the corresponding patterns. These requirements guarantee that a
|
||||
generated URL will always match a registered route -- the only exception is
|
||||
for explicitly defined "build-only" routes which never match.
|
||||
|
||||
Regex support also exists for matching Headers within a route. For example, we could do:
|
||||
|
||||
r.HeadersRegexp("Content-Type", "application/(text|json)")
|
||||
|
||||
...and the route will match both requests with a Content-Type of `application/json` as well as
|
||||
`application/text`
|
||||
|
||||
There's also a way to build only the URL host or path for a route:
|
||||
use the methods URLHost() or URLPath() instead. For the previous route,
|
||||
we would do:
|
||||
|
||||
// "http://news.domain.com/"
|
||||
host, err := r.Get("article").URLHost("subdomain", "news")
|
||||
|
||||
// "/articles/technology/42"
|
||||
path, err := r.Get("article").URLPath("category", "technology", "id", "42")
|
||||
|
||||
And if you use subrouters, host and path defined separately can be built
|
||||
as well:
|
||||
|
||||
r := mux.NewRouter()
|
||||
s := r.Host("{subdomain}.domain.com").Subrouter()
|
||||
s.Path("/articles/{category}/{id:[0-9]+}").
|
||||
HandlerFunc(ArticleHandler).
|
||||
Name("article")
|
||||
|
||||
// "http://news.domain.com/articles/technology/42"
|
||||
url, err := r.Get("article").URL("subdomain", "news",
|
||||
"category", "technology",
|
||||
"id", "42")
|
||||
|
||||
Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking.
|
||||
|
||||
type MiddlewareFunc func(http.Handler) http.Handler
|
||||
|
||||
Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created).
|
||||
|
||||
A very basic middleware which logs the URI of the request being handled could be written as:
|
||||
|
||||
func simpleMw(next http.Handler) http.Handler {
|
||||
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
|
||||
// Do stuff here
|
||||
log.Println(r.RequestURI)
|
||||
// Call the next handler, which can be another middleware in the chain, or the final handler.
|
||||
next.ServeHTTP(w, r)
|
||||
})
|
||||
}
|
||||
|
||||
Middlewares can be added to a router using `Router.Use()`:
|
||||
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/", handler)
|
||||
r.Use(simpleMw)
|
||||
|
||||
A more complex authentication middleware, which maps session token to users, could be written as:
|
||||
|
||||
// Define our struct
|
||||
type authenticationMiddleware struct {
|
||||
tokenUsers map[string]string
|
||||
}
|
||||
|
||||
// Initialize it somewhere
|
||||
func (amw *authenticationMiddleware) Populate() {
|
||||
amw.tokenUsers["00000000"] = "user0"
|
||||
amw.tokenUsers["aaaaaaaa"] = "userA"
|
||||
amw.tokenUsers["05f717e5"] = "randomUser"
|
||||
amw.tokenUsers["deadbeef"] = "user0"
|
||||
}
|
||||
|
||||
// Middleware function, which will be called for each request
|
||||
func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
|
||||
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
|
||||
token := r.Header.Get("X-Session-Token")
|
||||
|
||||
if user, found := amw.tokenUsers[token]; found {
|
||||
// We found the token in our map
|
||||
log.Printf("Authenticated user %s\n", user)
|
||||
next.ServeHTTP(w, r)
|
||||
} else {
|
||||
http.Error(w, "Forbidden", http.StatusForbidden)
|
||||
}
|
||||
})
|
||||
}
|
||||
|
||||
r := mux.NewRouter()
|
||||
r.HandleFunc("/", handler)
|
||||
|
||||
amw := authenticationMiddleware{tokenUsers: make(map[string]string)}
|
||||
amw.Populate()
|
||||
|
||||
r.Use(amw.Middleware)
|
||||
|
||||
Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to.

# GoDotEnv [![Build Status](https://travis-ci.org/joho/godotenv.svg?branch=master)](https://travis-ci.org/joho/godotenv) [![Build status](https://ci.appveyor.com/api/projects/status/9v40vnfvvgde64u4?svg=true)](https://ci.appveyor.com/project/joho/godotenv) [![Go Report Card](https://goreportcard.com/badge/github.com/joho/godotenv)](https://goreportcard.com/report/github.com/joho/godotenv)
|
||||
|
||||
A Go (golang) port of the Ruby dotenv project (which loads env vars from a .env file)
|
||||
|
||||
From the original Library:
|
||||
|
||||
> Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environments–such as resource handles for databases or credentials for external services–should be extracted from the code into environment variables.
|
||||
>
|
||||
> But it is not always practical to set environment variables on development machines or continuous integration servers where multiple projects are run. Dotenv load variables from a .env file into ENV when the environment is bootstrapped.
|
||||
|
||||
It can be used as a library (for loading in env for your own daemons etc) or as a bin command.
|
||||
|
||||
There is test coverage and CI for both linuxish and windows environments, but I make no guarantees about the bin version working on windows.
|
||||
|
||||
## Installation
|
||||
|
||||
As a library
|
||||
|
||||
```shell
|
||||
go get github.com/joho/godotenv
|
||||
```
|
||||
|
||||
or if you want to use it as a bin command
|
||||
```shell
|
||||
go get github.com/joho/godotenv/cmd/godotenv
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
Add your application configuration to your `.env` file in the root of your project:
|
||||
|
||||
```shell
|
||||
S3_BUCKET=YOURS3BUCKET
|
||||
SECRET_KEY=YOURSECRETKEYGOESHERE
|
||||
```
|
||||
|
||||
Then in your Go app you can do something like
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/joho/godotenv"
|
||||
"log"
|
||||
"os"
|
||||
)
|
||||
|
||||
func main() {
|
||||
err := godotenv.Load()
|
||||
if err != nil {
|
||||
log.Fatal("Error loading .env file")
|
||||
}
|
||||
|
||||
s3Bucket := os.Getenv("S3_BUCKET")
|
||||
secretKey := os.Getenv("SECRET_KEY")
|
||||
|
||||
// now do something with s3 or whatever
|
||||
}
|
||||
```
|
||||
|
||||
If you're even lazier than that, you can just take advantage of the autoload package which will read in `.env` on import
|
||||
|
||||
```go
|
||||
import _ "github.com/joho/godotenv/autoload"
|
||||
```
|
||||
|
||||
While `.env` in the project root is the default, you don't have to be constrained, both examples below are 100% legit
|
||||
|
||||
```go
|
||||
_ = godotenv.Load("somerandomfile")
|
||||
_ = godotenv.Load("filenumberone.env", "filenumbertwo.env")
|
||||
```
|
||||
|
||||
If you want to be really fancy with your env file you can do comments and exports (below is a valid env file)
|
||||
|
||||
```shell
|
||||
# I am a comment and that is OK
|
||||
SOME_VAR=someval
|
||||
FOO=BAR # comments at line end are OK too
|
||||
export BAR=BAZ
|
||||
```
|
||||
|
||||
Or finally you can do YAML(ish) style
|
||||
|
||||
```yaml
|
||||
FOO: bar
|
||||
BAR: baz
|
||||
```
|
||||
|
||||
as a final aside, if you don't want godotenv munging your env you can just get a map back instead
|
||||
|
||||
```go
|
||||
var myEnv map[string]string
|
||||
myEnv, err := godotenv.Read()
|
||||
|
||||
s3Bucket := myEnv["S3_BUCKET"]
|
||||
```
|
||||
|
||||
... or from an `io.Reader` instead of a local file
|
||||
|
||||
```go
|
||||
reader := getRemoteFile()
|
||||
myEnv, err := godotenv.Parse(reader)
|
||||
```
|
||||
|
||||
... or from a `string` if you so desire
|
||||
|
||||
```go
|
||||
content := getRemoteFileContent()
|
||||
myEnv, err := godotenv.Unmarshal(content)
|
||||
```
|
||||
|
||||
### Command Mode
|
||||
|
||||
Assuming you've installed the command as above and you've got `$GOPATH/bin` in your `$PATH`
|
||||
|
||||
```
|
||||
godotenv -f /some/path/to/.env some_command with some args
|
||||
```
|
||||
|
||||
If you don't specify `-f` it will fall back on the default of loading `.env` in `PWD`
|
||||
|
||||
### Writing Env Files
|
||||
|
||||
Godotenv can also write a map representing the environment to a correctly-formatted and escaped file
|
||||
|
||||
```go
|
||||
env, err := godotenv.Unmarshal("KEY=value")
|
||||
err := godotenv.Write(env, "./.env")
|
||||
```
|
||||
|
||||
... or to a string
|
||||
|
||||
```go
|
||||
env, err := godotenv.Unmarshal("KEY=value")
|
||||
content, err := godotenv.Marshal(env)
|
||||
```
|
||||
|
||||
## Contributing
|
||||
|
||||
Contributions are most welcome! The parser itself is pretty stupidly naive and I wouldn't be surprised if it breaks with edge cases.
|
||||
|
||||
*code changes without tests will not be accepted*
|
||||
|
||||
1. Fork it
|
||||
2. Create your feature branch (`git checkout -b my-new-feature`)
|
||||
3. Commit your changes (`git commit -am 'Added some feature'`)
|
||||
4. Push to the branch (`git push origin my-new-feature`)
|
||||
5. Create new Pull Request
|
||||
|
||||
## Releases
|
||||
|
||||
Releases should follow [Semver](http://semver.org/) though the first couple of releases are `v1` and `v1.1`.
|
||||
|
||||
Use [annotated tags for all releases](https://github.com/joho/godotenv/issues/30). Example `git tag -a v1.2.1`
|
||||
|
||||
## CI
|
||||
|
||||
Linux: [![Build Status](https://travis-ci.org/joho/godotenv.svg?branch=master)](https://travis-ci.org/joho/godotenv) Windows: [![Build status](https://ci.appveyor.com/api/projects/status/9v40vnfvvgde64u4)](https://ci.appveyor.com/project/joho/godotenv)
|
||||
|
||||
## Who?
|
||||
|
||||
The original library [dotenv](https://github.com/bkeepers/dotenv) was written by [Brandon Keepers](http://opensoul.org/), and this port was done by [John Barton](https://johnbarton.co/) based off the tests/fixtures in the original library.

)
|
||||
|
||||
func main() {
|
||||
sequences.EnableVirtualTerminalProcessing(syscall.Stdout, true)
|
||||
}
|
||||
|
||||
```

# Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/> [![Build Status](https://travis-ci.org/sirupsen/logrus.svg?branch=master)](https://travis-ci.org/sirupsen/logrus) [![GoDoc](https://godoc.org/github.com/sirupsen/logrus?status.svg)](https://godoc.org/github.com/sirupsen/logrus)
|
||||
|
||||
Logrus is a structured logger for Go (golang), completely API compatible with
|
||||
the standard library logger.
|
||||
|
||||
**Logrus is in maintenance-mode.** We will not be introducing new features. It's
|
||||
simply too hard to do in a way that won't break many people's projects, which is
|
||||
the last thing you want from your Logging library (again...).
|
||||
|
||||
This does not mean Logrus is dead. Logrus will continue to be maintained for
|
||||
security, (backwards compatible) bug fixes, and performance (where we are
|
||||
limited by the interface).
|
||||
|
||||
I believe Logrus' biggest contribution is to have played a part in today's
|
||||
widespread use of structured logging in Golang. There doesn't seem to be a
|
||||
reason to do a major, breaking iteration into Logrus V2, since the fantastic Go
|
||||
community has built those independently. Many fantastic alternatives have sprung
|
||||
up. Logrus would look like those, had it been re-designed with what we know
|
||||
about structured logging in Go today. Check out, for example,
|
||||
[Zerolog][zerolog], [Zap][zap], and [Apex][apex].
|
||||
|
||||
[zerolog]: https://github.com/rs/zerolog
|
||||
[zap]: https://github.com/uber-go/zap
|
||||
[apex]: https://github.com/apex/log
|
||||
|
||||
**Seeing weird case-sensitive problems?** It's in the past been possible to
|
||||
import Logrus as both upper- and lower-case. Due to the Go package environment,
|
||||
this caused issues in the community and we needed a standard. Some environments
|
||||
experienced problems with the upper-case variant, so the lower-case was decided.
|
||||
Everything using `logrus` will need to use the lower-case:
|
||||
`github.com/sirupsen/logrus`. Any package that isn't, should be changed.
|
||||
|
||||
To fix Glide, see [these
|
||||
comments](https://github.com/sirupsen/logrus/issues/553#issuecomment-306591437).
|
||||
For an in-depth explanation of the casing issue, see [this
|
||||
comment](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276).
|
||||
|
||||
Nicely color-coded in development (when a TTY is attached, otherwise just
|
||||
plain text):
|
||||
|
||||
![Colored](http://i.imgur.com/PY7qMwd.png)
|
||||
|
||||
With `log.SetFormatter(&log.JSONFormatter{})`, for easy parsing by logstash
|
||||
or Splunk:
|
||||
|
||||
```json
|
||||
{"animal":"walrus","level":"info","msg":"A group of walrus emerges from the
|
||||
ocean","size":10,"time":"2014-03-10 19:57:38.562264131 -0400 EDT"}
|
||||
|
||||
{"level":"warning","msg":"The group's number increased tremendously!",
|
||||
"number":122,"omg":true,"time":"2014-03-10 19:57:38.562471297 -0400 EDT"}
|
||||
|
||||
{"animal":"walrus","level":"info","msg":"A giant walrus appears!",
|
||||
"size":10,"time":"2014-03-10 19:57:38.562500591 -0400 EDT"}
|
||||
|
||||
{"animal":"walrus","level":"info","msg":"Tremendously sized cow enters the ocean.",
|
||||
"size":9,"time":"2014-03-10 19:57:38.562527896 -0400 EDT"}
|
||||
|
||||
{"level":"fatal","msg":"The ice breaks!","number":100,"omg":true,
|
||||
"time":"2014-03-10 19:57:38.562543128 -0400 EDT"}
|
||||
```
|
||||
|
||||
With the default `log.SetFormatter(&log.TextFormatter{})` when a TTY is not
|
||||
attached, the output is compatible with the
|
||||
[logfmt](http://godoc.org/github.com/kr/logfmt) format:
|
||||
|
||||
```text
|
||||
time="2015-03-26T01:27:38-04:00" level=debug msg="Started observing beach" animal=walrus number=8
|
||||
time="2015-03-26T01:27:38-04:00" level=info msg="A group of walrus emerges from the ocean" animal=walrus size=10
|
||||
time="2015-03-26T01:27:38-04:00" level=warning msg="The group's number increased tremendously!" number=122 omg=true
|
||||
time="2015-03-26T01:27:38-04:00" level=debug msg="Temperature changes" temperature=-4
|
||||
time="2015-03-26T01:27:38-04:00" level=panic msg="It's over 9000!" animal=orca size=9009
|
||||
time="2015-03-26T01:27:38-04:00" level=fatal msg="The ice breaks!" err=&{0x2082280c0 map[animal:orca size:9009] 2015-03-26 01:27:38.441574009 -0400 EDT panic It's over 9000!} number=100 omg=true
|
||||
```
|
||||
To ensure this behaviour even if a TTY is attached, set your formatter as follows:
|
||||
|
||||
```go
|
||||
log.SetFormatter(&log.TextFormatter{
|
||||
DisableColors: true,
|
||||
FullTimestamp: true,
|
||||
})
|
||||
```
|
||||
|
||||
#### Logging Method Name
|
||||
|
||||
If you wish to add the calling method as a field, instruct the logger via:
|
||||
```go
|
||||
log.SetReportCaller(true)
|
||||
```
|
||||
This adds the caller as 'method' like so:
|
||||
|
||||
```json
|
||||
{"animal":"penguin","level":"fatal","method":"github.com/sirupsen/arcticcreatures.migrate","msg":"a penguin swims by",
|
||||
"time":"2014-03-10 19:57:38.562543129 -0400 EDT"}
|
||||
```
|
||||
|
||||
```text
|
||||
time="2015-03-26T01:27:38-04:00" level=fatal method=github.com/sirupsen/arcticcreatures.migrate msg="a penguin swims by" animal=penguin
|
||||
```
|
||||
Note that this does add measurable overhead - the cost will depend on the version of Go, but is
|
||||
between 20 and 40% in recent tests with 1.6 and 1.7. You can validate this in your
|
||||
environment via benchmarks:
|
||||
```
|
||||
go test -bench=.*CallerTracing
|
||||
```
|
||||
|
||||
|
||||
#### Case-sensitivity
|
||||
|
||||
The organization's name was changed to lower-case--and this will not be changed
|
||||
back. If you are getting import conflicts due to case sensitivity, please use
|
||||
the lower-case import: `github.com/sirupsen/logrus`.
|
||||
|
||||
#### Example
|
||||
|
||||
The simplest way to use Logrus is simply the package-level exported logger:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
log "github.com/sirupsen/logrus"
|
||||
)
|
||||
|
||||
func main() {
|
||||
log.WithFields(log.Fields{
|
||||
"animal": "walrus",
|
||||
}).Info("A walrus appears")
|
||||
}
|
||||
```
|
||||
|
||||
Note that it's completely api-compatible with the stdlib logger, so you can
|
||||
replace your `log` imports everywhere with `log "github.com/sirupsen/logrus"`
|
||||
and you'll now have the flexibility of Logrus. You can customize it all you
|
||||
want:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"os"
|
||||
log "github.com/sirupsen/logrus"
|
||||
)
|
||||
|
||||
func init() {
|
||||
// Log as JSON instead of the default ASCII formatter.
|
||||
log.SetFormatter(&log.JSONFormatter{})
|
||||
|
||||
// Output to stdout instead of the default stderr
|
||||
// Can be any io.Writer, see below for File example
|
||||
log.SetOutput(os.Stdout)
|
||||
|
||||
// Only log the warning severity or above.
|
||||
log.SetLevel(log.WarnLevel)
|
||||
}
|
||||
|
||||
func main() {
|
||||
log.WithFields(log.Fields{
|
||||
"animal": "walrus",
|
||||
"size": 10,
|
||||
}).Info("A group of walrus emerges from the ocean")
|
||||
|
||||
log.WithFields(log.Fields{
|
||||
"omg": true,
|
||||
"number": 122,
|
||||
}).Warn("The group's number increased tremendously!")
|
||||
|
||||
log.WithFields(log.Fields{
|
||||
"omg": true,
|
||||
"number": 100,
|
||||
}).Fatal("The ice breaks!")
|
||||
|
||||
// A common pattern is to re-use fields between logging statements by re-using
|
||||
// the logrus.Entry returned from WithFields()
|
||||
contextLogger := log.WithFields(log.Fields{
|
||||
"common": "this is a common field",
|
||||
"other": "I also should be logged always",
|
||||
})
|
||||
|
||||
contextLogger.Info("I'll be logged with common and other field")
|
||||
contextLogger.Info("Me too")
|
||||
}
|
||||
```
|
||||
|
||||
For more advanced usage such as logging to multiple locations from the same
|
||||
application, you can also create an instance of the `logrus` Logger:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"os"
|
||||
"github.com/sirupsen/logrus"
|
||||
)
|
||||
|
||||
// Create a new instance of the logger. You can have any number of instances.
|
||||
var log = logrus.New()
|
||||
|
||||
func main() {
|
||||
// The API for setting attributes is a little different than the package level
|
||||
// exported logger. See Godoc.
|
||||
log.Out = os.Stdout
|
||||
|
||||
// You could set this to any `io.Writer` such as a file
|
||||
// file, err := os.OpenFile("logrus.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0666)
|
||||
// if err == nil {
|
||||
// log.Out = file
|
||||
// } else {
|
||||
// log.Info("Failed to log to file, using default stderr")
|
||||
// }
|
||||
|
||||
log.WithFields(logrus.Fields{
|
||||
"animal": "walrus",
|
||||
"size": 10,
|
||||
}).Info("A group of walrus emerges from the ocean")
|
||||
}
|
||||
```
|
||||
|
||||
#### Fields
|
||||
|
||||
Logrus encourages careful, structured logging through logging fields instead of
|
||||
long, unparseable error messages. For example, instead of: `log.Fatalf("Failed
|
||||
to send event %s to topic %s with key %d")`, you should log the much more
|
||||
discoverable:
|
||||
|
||||
```go
|
||||
log.WithFields(log.Fields{
|
||||
"event": event,
|
||||
"topic": topic,
|
||||
"key": key,
|
||||
}).Fatal("Failed to send event")
|
||||
```
|
||||
|
||||
We've found this API forces you to think about logging in a way that produces
|
||||
much more useful logging messages. We've been in countless situations where just
|
||||
a single added field to a log statement that was already there would've saved us
|
||||
hours. The `WithFields` call is optional.
|
||||
|
||||
In general, with Logrus using any of the `printf`-family functions should be
|
||||
seen as a hint you should add a field, however, you can still use the
|
||||
`printf`-family functions with Logrus.
|
||||
|
||||
#### Default Fields
|
||||
|
||||
Often it's helpful to have fields _always_ attached to log statements in an
|
||||
application or parts of one. For example, you may want to always log the
|
||||
`request_id` and `user_ip` in the context of a request. Instead of writing
|
||||
`log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})` on
|
||||
every line, you can create a `logrus.Entry` to pass around instead:
|
||||
|
||||
```go
|
||||
requestLogger := log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})
|
||||
requestLogger.Info("something happened on that request") # will log request_id and user_ip
|
||||
requestLogger.Warn("something not great happened")
|
||||
```
|
||||
|
||||
#### Hooks
|
||||
|
||||
You can add hooks for logging levels. For example to send errors to an exception
|
||||
tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to
|
||||
multiple places simultaneously, e.g. syslog.
|
||||
|
||||
Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in
|
||||
`init`:
|
||||
|
||||
```go
|
||||
import (
|
||||
log "github.com/sirupsen/logrus"
|
||||
"gopkg.in/gemnasium/logrus-airbrake-hook.v2" // the package is named "airbrake"
|
||||
logrus_syslog "github.com/sirupsen/logrus/hooks/syslog"
|
||||
"log/syslog"
|
||||
)
|
||||
|
||||
func init() {
|
||||
|
||||
// Use the Airbrake hook to report errors that have Error severity or above to
|
||||
// an exception tracker. You can create custom hooks, see the Hooks section.
|
||||
log.AddHook(airbrake.NewHook(123, "xyz", "production"))
|
||||
|
||||
hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
|
||||
if err != nil {
|
||||
log.Error("Unable to connect to local syslog daemon")
|
||||
} else {
|
||||
log.AddHook(hook)
|
||||
}
|
||||
}
|
||||
```
|
||||
Note: Syslog hook also support connecting to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). For the detail, please check the [syslog hook README](hooks/syslog/README.md).
|
||||
|
||||
A list of currently known service hooks can be found in this wiki [page](https://github.com/sirupsen/logrus/wiki/Hooks)
|
||||
|
||||
|
||||
#### Level logging
|
||||
|
||||
Logrus has seven logging levels: Trace, Debug, Info, Warning, Error, Fatal and Panic.
|
||||
|
||||
```go
|
||||
log.Trace("Something very low level.")
|
||||
log.Debug("Useful debugging information.")
|
||||
log.Info("Something noteworthy happened!")
|
||||
log.Warn("You should probably take a look at this.")
|
||||
log.Error("Something failed but I'm not quitting.")
|
||||
// Calls os.Exit(1) after logging
|
||||
log.Fatal("Bye.")
|
||||
// Calls panic() after logging
|
||||
log.Panic("I'm bailing.")
|
||||
```
|
||||
|
||||
You can set the logging level on a `Logger`, then it will only log entries with
|
||||
that severity or anything above it:
|
||||
|
||||
```go
|
||||
// Will log anything that is info or above (warn, error, fatal, panic). Default.
|
||||
log.SetLevel(log.InfoLevel)
|
||||
```
|
||||
|
||||
It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose
|
||||
environment if your application has that.
|
||||
|
||||
#### Entries
|
||||
|
||||
Besides the fields added with `WithField` or `WithFields` some fields are
|
||||
automatically added to all logging events:
|
||||
|
||||
1. `time`. The timestamp when the entry was created.
|
||||
2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after
|
||||
the `AddFields` call. E.g. `Failed to send event.`
|
||||
3. `level`. The logging level. E.g. `info`.
|
||||
|
||||
#### Environments
|
||||
|
||||
Logrus has no notion of environment.
|
||||
|
||||
If you wish for hooks and formatters to only be used in specific environments,
|
||||
you should handle that yourself. For example, if your application has a global
|
||||
variable `Environment`, which is a string representation of the environment you
|
||||
could do:
|
||||
|
||||
```go
|
||||
import (
|
||||
log "github.com/sirupsen/logrus"
|
||||
)
|
||||
|
||||
init() {
|
||||
// do something here to set environment depending on an environment variable
|
||||
// or command-line flag
|
||||
if Environment == "production" {
|
||||
log.SetFormatter(&log.JSONFormatter{})
|
||||
} else {
|
||||
// The TextFormatter is default, you don't actually have to do this.
|
||||
log.SetFormatter(&log.TextFormatter{})
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
This configuration is how `logrus` was intended to be used, but JSON in
|
||||
production is mostly only useful if you do log aggregation with tools like
|
||||
Splunk or Logstash.
|
||||
|
||||
#### Formatters
|
||||
|
||||
The built-in logging formatters are:
|
||||
|
||||
* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise
|
||||
without colors.
|
||||
* *Note:* to force colored output when there is no TTY, set the `ForceColors`
|
||||
field to `true`. To force no colored output even if there is a TTY set the
|
||||
`DisableColors` field to `true`. For Windows, see
|
||||
[github.com/mattn/go-colorable](https://github.com/mattn/go-colorable).
|
||||
* When colors are enabled, levels are truncated to 4 characters by default. To disable
|
||||
truncation set the `DisableLevelTruncation` field to `true`.
|
||||
* When outputting to a TTY, it's often helpful to visually scan down a column where all the levels are the same width. Setting the `PadLevelText` field to `true` enables this behavior, by adding padding to the level text.
|
||||
* All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#TextFormatter).
|
||||
* `logrus.JSONFormatter`. Logs fields as JSON.
|
||||
* All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#JSONFormatter).
|
||||
|
||||
Third party logging formatters:
|
||||
|
||||
* [`FluentdFormatter`](https://github.com/joonix/log). Formats entries that can be parsed by Kubernetes and Google Container Engine.
|
||||
* [`GELF`](https://github.com/fabienm/go-logrus-formatters). Formats entries so they comply to Graylog's [GELF 1.1 specification](http://docs.graylog.org/en/2.4/pages/gelf.html).
|
||||
* [`logstash`](https://github.com/bshuster-repo/logrus-logstash-hook). Logs fields as [Logstash](http://logstash.net) Events.
|
||||
* [`prefixed`](https://github.com/x-cray/logrus-prefixed-formatter). Displays log entry source along with alternative layout.
|
||||
* [`zalgo`](https://github.com/aybabtme/logzalgo). Invoking the Power of Zalgo.
|
||||
* [`nested-logrus-formatter`](https://github.com/antonfisher/nested-logrus-formatter). Converts logrus fields to a nested structure.
|
||||
* [`powerful-logrus-formatter`](https://github.com/zput/zxcTool). get fileName, log's line number and the latest function's name when print log; Sava log to files.
|
||||
* [`caption-json-formatter`](https://github.com/nolleh/caption_json_formatter). logrus's message json formatter with human-readable caption added.
|
||||
|
||||
You can define your formatter by implementing the `Formatter` interface,
|
||||
requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a
|
||||
`Fields` type (`map[string]interface{}`) with all your fields as well as the
|
||||
default ones (see Entries section above):
|
||||
|
||||
```go
|
||||
type MyJSONFormatter struct {
|
||||
}
|
||||
|
||||
log.SetFormatter(new(MyJSONFormatter))
|
||||
|
||||
func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) {
|
||||
// Note this doesn't include Time, Level and Message which are available on
|
||||
// the Entry. Consult `godoc` on information about those fields or read the
|
||||
// source of the official loggers.
|
||||
serialized, err := json.Marshal(entry.Data)
|
||||
if err != nil {
|
||||
return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err)
|
||||
}
|
||||
return append(serialized, '\n'), nil
|
||||
}
|
||||
```
|
||||
|
||||
#### Logger as an `io.Writer`
|
||||
|
||||
Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it.
|
||||
|
||||
```go
|
||||
w := logger.Writer()
|
||||
defer w.Close()
|
||||
|
||||
srv := http.Server{
|
||||
// create a stdlib log.Logger that writes to
|
||||
// logrus.Logger.
|
||||
ErrorLog: log.New(w, "", 0),
|
||||
}
|
||||
```
|
||||
|
||||
Each line written to that writer will be printed the usual way, using formatters
|
||||
and hooks. The level for those entries is `info`.
|
||||
|
||||
This means that we can override the standard library logger easily:
|
||||
|
||||
```go
|
||||
logger := logrus.New()
|
||||
logger.Formatter = &logrus.JSONFormatter{}
|
||||
|
||||
// Use logrus for standard log output
|
||||
// Note that `log` here references stdlib's log
|
||||
// Not logrus imported under the name `log`.
|
||||
log.SetOutput(logger.Writer())
|
||||
```
|
||||
|
||||
#### Rotation
|
||||
|
||||
Log rotation is not provided with Logrus. Log rotation should be done by an
|
||||
external program (like `logrotate(8)`) that can compress and delete old log
|
||||
entries. It should not be a feature of the application-level logger.
|
||||
|
||||
#### Tools
|
||||
|
||||
| Tool | Description |
|
||||
| ---- | ----------- |
|
||||
|[Logrus Mate](https://github.com/gogap/logrus_mate)|Logrus mate is a tool for Logrus to manage loggers, you can initial logger's level, hook and formatter by config file, the logger will be generated with different configs in different environments.|
|
||||
|[Logrus Viper Helper](https://github.com/heirko/go-contrib/tree/master/logrusHelper)|An Helper around Logrus to wrap with spf13/Viper to load configuration with fangs! And to simplify Logrus configuration use some behavior of [Logrus Mate](https://github.com/gogap/logrus_mate). [sample](https://github.com/heirko/iris-contrib/blob/master/middleware/logrus-logger/example) |
|
||||
|
||||
#### Testing
|
||||
|
||||
Logrus has a built in facility for asserting the presence of log messages. This is implemented through the `test` hook and provides:
|
||||
|
||||
* decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just adds the `test` hook
|
||||
* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any):
|
||||
|
||||
```go
|
||||
import(
|
||||
"github.com/sirupsen/logrus"
|
||||
"github.com/sirupsen/logrus/hooks/test"
|
||||
"github.com/stretchr/testify/assert"
|
||||
"testing"
|
||||
)
|
||||
|
||||
func TestSomething(t*testing.T){
|
||||
logger, hook := test.NewNullLogger()
|
||||
logger.Error("Helloerror")
|
||||
|
||||
assert.Equal(t, 1, len(hook.Entries))
|
||||
assert.Equal(t, logrus.ErrorLevel, hook.LastEntry().Level)
|
||||
assert.Equal(t, "Helloerror", hook.LastEntry().Message)
|
||||
|
||||
hook.Reset()
|
||||
assert.Nil(t, hook.LastEntry())
|
||||
}
|
||||
```
|
||||
|
||||
#### Fatal handlers
|
||||
|
||||
Logrus can register one or more functions that will be called when any `fatal`
|
||||
level message is logged. The registered handlers will be executed before
|
||||
logrus performs an `os.Exit(1)`. This behavior may be helpful if callers need
|
||||
to gracefully shutdown. Unlike a `panic("Something went wrong...")` call which can be intercepted with a deferred `recover` a call to `os.Exit(1)` can not be intercepted.
|
||||
|
||||
```
|
||||
...
|
||||
handler := func() {
|
||||
// gracefully shutdown something...
|
||||
}
|
||||
logrus.RegisterExitHandler(handler)
|
||||
...
|
||||
```
|
||||
|
||||
#### Thread safety
|
||||
|
||||
By default, Logger is protected by a mutex for concurrent writes. The mutex is held when calling hooks and writing logs.
|
||||
If you are sure such locking is not needed, you can call logger.SetNoLock() to disable the locking.
|
||||
|
||||
Situation when locking is not needed includes:
|
||||
|
||||
* You have no hooks registered, or hooks calling is already thread-safe.
|
||||
|
||||
* Writing to logger.Out is already thread-safe, for example:
|
||||
|
||||
1) logger.Out is protected by locks.
|
||||
|
||||
2) logger.Out is an os.File handler opened with `O_APPEND` flag, and every write is smaller than 4k. (This allows multi-thread/multi-process writing)

/*
|
||||
Package logrus is a structured logger for Go, completely API compatible with the standard library logger.
|
||||
|
||||
|
||||
The simplest way to use Logrus is simply the package-level exported logger:
|
||||
|
||||
package main
|
||||
|
||||
import (
|
||||
log "github.com/sirupsen/logrus"
|
||||
)
|
||||
|
||||
func main() {
|
||||
log.WithFields(log.Fields{
|
||||
"animal": "walrus",
|
||||
"number": 1,

# Building `sys/unix`
|
||||
|
||||
The sys/unix package provides access to the raw system call interface of the
|
||||
underlying operating system. See: https://godoc.org/golang.org/x/sys/unix
|
||||
|
||||
Porting Go to a new architecture/OS combination or adding syscalls, types, or
|
||||
constants to an existing architecture/OS pair requires some manual effort;
|
||||
however, there are tools that automate much of the process.
|
||||
|
||||
## Build Systems
|
||||
|
||||
There are currently two ways we generate the necessary files. We are currently
|
||||
migrating the build system to use containers so the builds are reproducible.
|
||||
This is being done on an OS-by-OS basis. Please update this documentation as
|
||||
components of the build system change.
|
||||
|
||||
### Old Build System (currently for `GOOS != "linux"`)
|
||||
|
||||
The old build system generates the Go files based on the C header files
|
||||
present on your system. This means that files
|
||||
for a given GOOS/GOARCH pair must be generated on a system with that OS and
|
||||
architecture. This also means that the generated code can differ from system
|
||||
to system, based on differences in the header files.
|
||||
|
||||
To avoid this, if you are using the old build system, only generate the Go
|
||||
files on an installation with unmodified header files. It is also important to
|
||||
keep track of which version of the OS the files were generated from (ex.
|
||||
Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes
|
||||
and have each OS upgrade correspond to a single change.
|
||||
|
||||
To build the files for your current OS and architecture, make sure GOOS and
|
||||
GOARCH are set correctly and run `mkall.sh`. This will generate the files for
|
||||
your specific system. Running `mkall.sh -n` shows the commands that will be run.
|
||||
|
||||
Requirements: bash, go
|
||||
|
||||
### New Build System (currently for `GOOS == "linux"`)
|
||||
|
||||
The new build system uses a Docker container to generate the go files directly
|
||||
from source checkouts of the kernel and various system libraries. This means
|
||||
that on any platform that supports Docker, all the files using the new build
|
||||
system can be generated at once, and generated files will not change based on
|
||||
what the person running the scripts has installed on their computer.
|
||||
|
||||
The OS specific files for the new build system are located in the `${GOOS}`
|
||||
directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When
|
||||
the kernel or system library updates, modify the Dockerfile at
|
||||
`${GOOS}/Dockerfile` to checkout the new release of the source.
|
||||
|
||||
To build all the files under the new build system, you must be on an amd64/Linux
|
||||
system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will
|
||||
then generate all of the files for all of the GOOS/GOARCH pairs in the new build
|
||||
system. Running `mkall.sh -n` shows the commands that will be run.
|
||||
|
||||
Requirements: bash, go, docker
|
||||
|
||||
## Component files
|
||||
|
||||
This section describes the various files used in the code generation process.
|
||||
It also contains instructions on how to modify these files to add a new
|
||||
architecture/OS or to add additional syscalls, types, or constants. Note that
|
||||
if you are using the new build system, the scripts/programs cannot be called normally.
|
||||
They must be called from within the docker container.
|
||||
|
||||
### asm files
|
||||
|
||||
The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system
|
||||
call dispatch. There are three entry points:
|
||||
```
|
||||
func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
|
||||
func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
|
||||
func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
|
||||
```
|
||||
The first and second are the standard ones; they differ only in how many
|
||||
arguments can be passed to the kernel. The third is for low-level use by the
|
||||
ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
|
||||
let it know that a system call is running.
|
||||
|
||||
When porting Go to an new architecture/OS, this file must be implemented for
|
||||
each GOOS/GOARCH pair.
|
||||
|
||||
### mksysnum
|
||||
|
||||
Mksysnum is a Go program located at `${GOOS}/mksysnum.go` (or `mksysnum_${GOOS}.go`
|
||||
for the old system). This program takes in a list of header files containing the
|
||||
syscall number declarations and parses them to produce the corresponding list of
|
||||
Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated
|
||||
constants.
|
||||
|
||||
Adding new syscall numbers is mostly done by running the build on a sufficiently
|
||||
new installation of the target OS (or updating the source checkouts for the
|
||||
new build system). However, depending on the OS, you make need to update the
|
||||
parsing in mksysnum.
|
||||
|
||||
### mksyscall.go
|
||||
|
||||
The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are
|
||||
hand-written Go files which implement system calls (for unix, the specific OS,
|
||||
or the specific OS/Architecture pair respectively) that need special handling
|
||||
and list `//sys` comments giving prototypes for ones that can be generated.
|
||||
|
||||
The mksyscall.go program takes the `//sys` and `//sysnb` comments and converts
|
||||
them into syscalls. This requires the name of the prototype in the comment to
|
||||
match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function
|
||||
prototype can be exported (capitalized) or not.
|
||||
|
||||
Adding a new syscall often just requires adding a new `//sys` function prototype
|
||||
with the desired arguments and a capitalized name so it is exported. However, if
|
||||
you want the interface to the syscall to be different, often one will make an
|
||||
unexported `//sys` prototype, an then write a custom wrapper in
|
||||
`syscall_${GOOS}.go`.
|
||||
|
||||
### types files
|
||||
|
||||
For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or
|
||||
`types_${GOOS}.go` on the old system). This file includes standard C headers and
|
||||
creates Go type aliases to the corresponding C types. The file is then fed
|
||||
through godef to get the Go compatible definitions. Finally, the generated code
|
||||
is fed though mkpost.go to format the code correctly and remove any hidden or
|
||||
private identifiers. This cleaned-up code is written to
|
||||
`ztypes_${GOOS}_${GOARCH}.go`.
|
||||
|
||||
The hardest part about preparing this file is figuring out which headers to
|
||||
include and which symbols need to be `#define`d to get the actual data
|
||||
structures that pass through to the kernel system calls. Some C libraries
|
||||
preset alternate versions for binary compatibility and translate them on the
|
||||
way in and out of system calls, but there is almost always a `#define` that can
|
||||
get the real ones.
|
||||
See `types_darwin.go` and `linux/types.go` for examples.
|
||||
|
||||
To add a new type, add in the necessary include statement at the top of the
|
||||
file (if it is not already there) and add in a type alias line. Note that if
|
||||
your type is significantly different on different architectures, you may need
|
||||
some `#if/#elif` macros in your include statements.
|
||||
|
||||
### mkerrors.sh
|
||||
|
||||
This script is used to generate the system's various constants. This doesn't
|
||||
just include the error numbers and error strings, but also the signal numbers
|
||||
an a wide variety of miscellaneous constants. The constants come from the list
|
||||
of include files in the `includes_${uname}` variable. A regex then picks out
|
||||
the desired `#define` statements, and generates the corresponding Go constants.
|
||||
The error numbers and strings are generated from `#include <errno.h>`, and the
|
||||
signal numbers and strings are generated from `#include <signal.h>`. All of
|
||||
these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program,
|
||||
`_errors.c`, which prints out all the constants.
|
||||
|
||||
To add a constant, add the header that includes it to the appropriate variable.
|
||||
Then, edit the regex (if necessary) to match the desired constant. Avoid making
|
||||
the regex too broad to avoid matching unintended constants.
|
||||
|
||||
|
||||
## Generated files
|
||||
|
||||
### `zerror_${GOOS}_${GOARCH}.go`
|
||||
|
||||
A file containing all of the system's generated error numbers, error strings,
|
||||
signal numbers, and constants. Generated by `mkerrors.sh` (see above).
|
||||
|
||||
### `zsyscall_${GOOS}_${GOARCH}.go`
|
||||
|
||||
A file containing all the generated syscalls for a specific GOOS and GOARCH.
|
||||
Generated by `mksyscall.go` (see above).
|
||||
|
||||
### `zsysnum_${GOOS}_${GOARCH}.go`
|
||||
|
||||
A list of numeric constants for all the syscall number of the specific GOOS
|
||||
and GOARCH. Generated by mksysnum (see above).
|
||||
|
||||
### `ztypes_${GOOS}_${GOARCH}.go`
|
||||
|
||||
A file containing Go types for passing into (or returning from) syscalls.
|
||||
Generated by godefs and the types file (see above).
