Controller is the base class for RESTful API controller classes.

Controller implements the following steps in a RESTful API request handling cycle:

  1. Resolving response format (see yii\filters\ContentNegotiator);
  2. Validating request method (see verbs()).
  3. Authenticating user (see yii\filters\auth\AuthInterface);
  4. Rate limiting (see yii\filters\RateLimiter);
  5. Formatting response data (see serializeData()).

For more details and usage information on Controller, see the guide article on rest controllers.

属性详情

$enableCsrfValidation public 属性

Whether to enable CSRF validation for the actions in this controller. CSRF validation is enabled only when both this property and yii\web\Request::$enableCsrfValidation are true.

$serializer public 属性

The configuration for creating the serializer that formats the response data.

public string|array $serializer 'yii\rest\Serializer'

方法详情

afterAction() public 方法

This method is invoked right after an action is executed.

The method will trigger the EVENT_AFTER_ACTION event. The return value of the method will be used as the action return value.

If you override this method, your code should look like the following:

public function afterAction($action, $result)
{
    $result = parent::afterAction($action, $result);
    // your custom code here
    return $result;
}
public mixed afterAction ( $action, $result )
$action yii\base\Action

The action just executed.

$result mixed

The action return result.

return mixed

The processed action result.

behaviors() public 方法

返回此组件应该具有的行为列表.

子类可以重写此方法来指定他们应该具有的行为.

此方法的返回值应该是行为对象数组或由行为名称索引的配置. 行为配置可以是指定行为类的字符串, 也可以是以下结构的数组:

'behaviorName' => [
    'class' => 'BehaviorClass',
    'property1' => 'value1',
    'property2' => 'value2',
]

Note: 行为类必须从 \yii\rest\Behavior 扩展. 可以使用名称或匿名方式附加行为. 当使用名称作为数组键时, 使用此名称, 稍后可以使用 getBehavior() 检索该行为, 或者使用 detachBehavior() 进行分离. 匿名行为无法检索或分离.

在此方法中声明的行为将自动(按需)附加到组件上.

public array behaviors ( )
return array

行为配置.

serializeData() protected 方法

Serializes the specified data.

The default implementation will create a serializer based on the configuration given by $serializer. It then uses the serializer to serialize the given data.

protected mixed serializeData ( $data )
$data mixed

The data to be serialized

return mixed

The serialized data.

verbs() protected 方法

Declares the allowed HTTP verbs.

Please refer to yii\filters\VerbFilter::$actions on how to declare the allowed verbs.

protected array verbs ( )
return array

The allowed HTTP verbs.
