Yii中特殊行為ActionFilter如何使用?很多新手對此不是很清楚,為了幫助大家解決這個難題,下面小編將為大家詳細講解,有這方面需求的人可以來學習下,希望你能有所收獲。
新建 app\filters\LoggingFilter 繼承 yii\base\ActionFilter
LoggingFilter 的功能: 在指定請求的 action 前后各記錄一條日志
<?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
<?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'], // 僅對 '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); } }
測試
請求 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.
請求 http://yii.test/index.php?r=system/test-one
This is a testing for system/test-one.
請求 http://yii.test/index.php?r=system/test-two
This is a testing for system/test-two.
