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.
