Yii 中特殊行为 ActionFilter 的使用示例
码农天地 -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 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.
请求 http://yii.test/index.php?r=system/test-one
This is a testing for system/test-one.
请求 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。
