Yii中使用ActionFilter的示例

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

LoggingFilter 的功能: 在指定请求的 action 前后各记录一条日志

<?php

namespace appfilters;

use yiibaseActionFilter;

class LoggingFilter extends ActionFilter
{
 public function beforeAction($action)
 {
  parent::beforeAction($action);

  // To do something
  printf(This is a logging for %sbeforeAction.%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 %safterAction.%s, $this->getActionId($action), PHP_EOL);

  return true;
 }
}

新建 appcontrollersSystemController

<?php

namespace appcontrollers;

use appfiltersLoggingFilter;

class SystemController extends yiiwebController
{
 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);
 }
}

请求 http://yii.test/index.php?r=system/test

This is a logging for testbeforeAction.
This is a testing for system/test.
This is a logging for testafterAction.

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.

Yii中特殊行为ActionFilter的使用方法示例

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。
