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
<?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'], // 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
this is a logging for test\beforeaction. this is a testing for system/test. this is a logging for test\afteraction.
请求
this is a testing for system/test-one.
请求
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。
