Symfony2 redirect for event listener?
提问by Jonah Katz
I have a kernel event listener setup (kernel.controller) to redirect the user if hes not logged in. The event listener is succefully getting called, however im having trouble figuring out how to redirect. Here's what i got:
我有一个内核事件监听器设置 (kernel.controller) 来重定向用户，如果他没有登录。事件监听器被成功调用，但是我无法弄清楚如何重定向。这是我得到的：
$cont = $event->getController('testpost');
$event->setResponse($cont);
Which gives me the error:
这给了我错误：
Fatal error: Call to undefined method Symfony\Component\HttpKernel\Event\FilterControllerEvent::setResponse()

If you wanna redirect from FilterControllerEventyou should use this one:
如果你想重定向，FilterControllerEvent你应该使用这个：
public function onKernelController(FilterControllerEvent $event)
{
// do something
$event->setController(function() use ($redirectUrl) {
return new RedirectResponse($redirectUrl);
});
}

You can't set a response to a FilterControllerEventobject. You need to listen for the kernel.requestevent because its GetResponseEventobject has the setResponse()method:
您无法设置对FilterControllerEvent对象的响应。您需要侦听该kernel.request事件，因为它的GetResponseEvent对象具有以下setResponse()方法：
$route = 'route_name';
if ($route === $event->getRequest()->get('_route')) {
return;
}
$url = $this->router->generate($route);
$response = new RedirectResponse($url);
$event->setResponse($response);

More ore less clear way to redirect on 'kernel.controller' event
更多或不太清楚的重定向“kernel.controller”事件的方法
public function onKernelController(FilterControllerEvent $event)
{
/* @var $controller \Symfony\Bundle\FrameworkBundle\Controller\Controller */
$controller = $event->getController()[0]; // PHP 5.4 or $controller = $controller[0];
throw new HttpException(307, null, null, array('Location' => $controller->generateUrl('homepage')));
}

Here is a similar question about doing (almost) the same thing. It should give you a clue.
这是一个关于做（几乎）同样事情的类似问题。它应该给你一个线索。

This ain't no way to go, my friend. You should use a default Symfony Security to cover that for you...
这不是没有办法，我的朋友。您应该使用默认的 Symfony Security 来为您覆盖...
