Class yii\rest\UrlRule
| Inheritance | yii\rest\UrlRule » yii\web\CompositeUrlRule » yii\base\BaseObject |
|---|---|
| Implements | yii\base\Configurable, yii\web\UrlRuleInterface |
| Available since version | 2.0 |
| Source Code | https://github.com/yiisoft/yii2/blob/master/framework/rest/UrlRule.php |
UrlRule is provided to simplify the creation of URL rules for RESTful API support.
The simplest usage of UrlRule is to declare a rule like the following in the application configuration,
[
'class' => 'yii\rest\UrlRule',
'controller' => 'user',
]
The above code will create a whole set of URL rules supporting the following RESTful API endpoints:
'PUT,PATCH users/<id>' => 'user/update': update a user'DELETE users/<id>' => 'user/delete': delete a user'GET,HEAD users/<id>' => 'user/view': return the details/overview/options of a user'POST users' => 'user/create': create a new user'GET,HEAD users' => 'user/index': return a list/overview/options of users'users/<id>' => 'user/options': process all unhandled verbs of a user'users' => 'user/options': process all unhandled verbs of user collection
You may configure $only and/or $except to disable some of the above rules.
You may configure $patterns to completely redefine your own list of rules.
You may configure $controller with multiple controller IDs to generate rules for all these controllers.
For example, the following code will disable the delete rule and generate rules for both user and post controllers:
[
'class' => 'yii\rest\UrlRule',
'controller' => ['user', 'post'],
'except' => ['delete'],
]
The property $controller is required and should represent one or multiple controller IDs.
Each controller ID should be prefixed with the module ID if the controller is within a module.
The controller ID used in the pattern will be automatically pluralized (e.g. user becomes users
as shown in the above examples).
For more details and usage information on UrlRule, see the guide article on rest routing.

Property Details
The controller ID (e.g. user, post-comment) that the rules in this composite rule
are dealing with. It should be prefixed with the module ID if the controller is within a module (e.g. admin/user).
By default, the controller ID will be pluralized automatically when it is put in the patterns of the
generated rules. If you want to explicitly specify how the controller ID should appear in the patterns,
you may use an array with the array key being as the controller ID in the pattern, and the array value
the actual controller ID. For example, ['u' => 'user'].
You may also pass multiple controller IDs as an array. If this is the case, this composite rule will
generate applicable URL rules for EVERY specified controller. For example, ['user', 'post'].
List of actions that should be excluded. Any action found in this array will NOT have its URL rules created.
See also $patterns.
Patterns for supporting extra actions in addition to those listed in $patterns. The keys are the patterns and the values are the corresponding action IDs. These extra patterns will take precedence over $patterns.
List of acceptable actions. If not empty, only the actions within this array will have the corresponding URL rules created.
See also $patterns.
List of possible patterns and the corresponding actions for creating the URL rules.
The keys are the patterns and the values are the corresponding actions.
The format of patterns is Verbs Pattern, where Verbs stands for a list of HTTP verbs separated
by comma (without space). If Verbs is not specified, it means all verbs are allowed.
Pattern is optional. It will be prefixed with $prefix/$controller/,
and tokens in it will be replaced by $tokens.
Whether to automatically pluralize the URL names for controllers.
If true, a controller ID will appear in plural form in URLs. For example, user controller
will appear as users in URLs.
See also $controller.
The common prefix string shared by all patterns.
The default configuration for creating each URL rule contained by this rule.
The suffix that will be assigned to yii\web\UrlRule::$suffix for every generated rule.
List of tokens that should be replaced for each pattern. The keys are the token names, and the values are the corresponding replacements.
See also $patterns.
