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

<?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

1

2

3

This is a logging for test\beforeAction.

This is a testing for system/test.

This is a logging for test\afterAction.

1	`This is a testing` `for` `system/test-one.`

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。
