我有一个简单的代码在我的应用程序的 beforeAction 事件上运行:
'on beforeAction' => function ($event) {
throw new \yii\web\NotFoundHttpException('The requested page does not exist.');
},
我希望它只显示我的应用程序的 404 页面,但它抛出以下错误:
An Error occurred while handling another error:

最佳答案
ErrorHandler.php
文件中的问题 85 line :
$result = Yii::$app->runAction($this->errorAction);
当 ErrorHandler
尝试运行 ErrorAction
时,NotFoundHttpException
再次触发并且 ErrorHandler
只显示错误消息而不渲染。
解决方法:
public function beforeAction($action)
{
if(!$action instanceof \yii\web\ErrorAction) {
throw new \yii\web\NotFoundHttpException('The requested page does not exist.');
}
return parent::beforeAction($action);
}
上一个答案:
在生产服务器上还需要在 index.php
文件中设置正确的环境设置:
defined('YII_DEBUG') or define('YII_DEBUG', false);
defined('YII_ENV') or define('YII_ENV', 'prod');
