在控制器内不做任何事情会返回"未捕获的异常'Symfony'Component'Routing' exception 'ResourceNotFoundException' in…"错误。不确定这是对的，还是这是另一个问题。我希望它只做通常的动作。
我只需要这样做，这样它就会显示一个指定的路由，就像我去domain.com/page一样。
我试过了:
$httpKernel = $this->container->get('kernel');
$response = $httpKernel->forward('AcmeMyBundle:Default:pageAction');
$this->setResponse(new Response($response));
…但是得到这个错误:
Call to a member function get() on a non-object in...
你的代码看起来和我昨天做的很像。我想获得所有NotFoundHttpException异常，并尝试将它们转发到默认控制器。我通过一个异常监听器实现了这一点，如下所示:
<?php
namespace Acme'MyBundle'Listener;
use Symfony'Component'HttpKernel'Exception'NotFoundHttpException;
use Symfony'Component'HttpKernel'Event'GetResponseForExceptionEvent;
class NotFoundHttpExceptionListener
{
protected $container;
public function setContainer($container)
{
$this->container = $container;
}
public function onKernelException(GetResponseForExceptionEvent $event)
{
$exception = $event->getException();
if ($exception instanceof NotFoundHttpException) {
$httpKernel = $this->container->get('http_kernel');
$response = $httpKernel->forward(
'AcmeMyBundle:Controller:action',
array(
'uri' => $_SERVER['REQUEST_URI'],
)
);
$response->headers->set('X-Status-Code', '200');
$event->setResponse($response);
$event->stopPropagation();
}
}
}
注意，X-Status-Code是必要的，如果你想返回另一个状态码比404，因为HttpKernel中的handleException方法将使用它来设置最终状态码，并从头部分删除它。
我的服务。Yml看起来像这样:
notfoundhttp.exception.listener:
class: Acme'MyBundle'Listener'NotFoundHttpExceptionListener
calls:
- [ setContainer, [@service_container] ]
tags:
- { name: kernel.event_listener, event: kernel.exception, method: onKernelException }
