新建 app\filters\LoggingFilter 继承 yii\base\ActionFilter
LoggingFilter 的性能: 在指定申请的 action 前后各记录一条日志
<?phpnamespace 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
<?phpnamespace 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' 失效 '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
申请 http://yii.test/index.php?r=system/test
This is a logging for test\beforeAction.This is a testing for system/test.This is a logging for test\afterAction.申请 http://yii.test/index.php?r=system/test-one
This is a testing for system/test-one.申请 http://yii.test/index.php?r=system/test-two
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。
