Yii中特殊行为ActionFilter的使用方法示例
这篇文章主要给大家介绍了关于Yii中特殊行为ActionFilter的使用方法,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧
新建 app\filters\LoggingFilter 继承 yii\base\ActionFilter
LoggingFilter 的功能: 在指定请求的 action 前后各记录一条日志
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | <?php namespace app\filters; use yii\base\ActionFilter; class LoggingFilter extends ActionFilter { public function beforeAction( $action ) { parent::beforeAction( $action ); // To do something printf( 'This is a logging for %s\beforeAction.%s' , $this ->getActionId( $action ), PHP_EOL); return true; } public function afterAction( $action , $result ) { parent::afterAction( $action , $result ); // To do something printf( 'This is a logging for %s\afterAction.%s' , $this ->getActionId( $action ), PHP_EOL); return true; } } |
新建 app\controllers\SystemController
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 | <?php namespace app\controllers; use app\filters\LoggingFilter; class SystemController extends \yii\web\Controller { public function behaviors() { parent::behaviors(); return [ 'anchorAuth' => [ 'class' => LoggingFilter::className(), 'only' => [ 'test' , 'test-one' ], // 仅对 'test'、'test-one' 生效 'except' => [ 'test-one' ], // 排除 'test-one' ], ]; } public function actionTestOne() { printf( 'This is a testing for %s.%s' , $this ->getRoute(), PHP_EOL); } public function actionTestTwo() { printf( 'This is a testing for %s.%s' , $this ->getRoute(), PHP_EOL); } public function actionTest() { printf( 'This is a testing for %s.%s' , $this ->getRoute(), PHP_EOL); } } |
测试
请求 http://yii.test/index.php?r=system/test
1 2 3 | This is a logging for test\beforeAction. This is a testing for system/test. This is a logging for test\afterAction. |
请求 http://yii.test/index.php?r=system/test-one
1 | This is a testing for system/test-one. |
请求 http://yii.test/index.php?r=system/test-two
1 | This is a testing for system/test-two. |
总结
Yii 中的 ActionFilter(过滤器)相当于 Laravel 中的 Middleware(中间件),beforeAction 相当于前置中间件,afterAction 相当于后置中间件。
