当symfony抛出异常时,我需要从EventListener重定向到自定义URL
在我的service.yml
中app.exception_listener:
class: AppBundle\EventListener\ExceptionListener
tags:
- { name: kernel.event_listener, event: kernel.exception, method: onKernelException }
在我的php课程中
<?php
namespace AppBundle\EventListener;
use Symfony\Component\HttpKernel\Event\GetResponseForExceptionEvent;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\Exception\HttpExceptionInterface;
use Symfony\Component\DependencyInjection\Container;
use Symfony\Component\HttpFoundation\RedirectResponse;
class ExceptionListener {
public function onKernelException(GetResponseForExceptionEvent $event) {
// You get the exception object from the received event
$exception = $event->getException();
if ($exception instanceof NotFoundHttpException) {
//i need this function
return $this->redirect('https://www.google.co.ve/?gws_rd=ssl', 404);
}
}
}
答案 0 :(得分:7)
而不是:
返回$ this-&gt;重定向(&#39; https://www.google.co.ve/?gws_rd=ssl&#39;,404);
做的:
$事件 - &GT; setResponse(新 RedirectResponse(&#39; https://www.google.co.ve/?gws_rd=ssl&#39;));
另请注意,发送带有404响应的Location标头并不合理,您应该使用3xx范围内的响应。在尝试使用其他状态代码重定向时,Symfony实际上(正确地)会抛出异常。
