Symfony2 重定向事件侦听器？

Question

I have a kernel event listener setup (kernel.controller) to redirect the user if he's not logged in. The event listener is succesfully getting called, however I'm having trouble figuring out how to redirect. Here's what I got:

$cont = $event->getController('testpost');
$event->setResponse($cont);

Which gives me the error:

Fatal error: Call to undefined method Symfony\Component\HttpKernel\Event\FilterControllerEvent::setResponse() 

Answer 1

If you wanna redirect from FilterControllerEvent you should use this one:

public function onKernelController(FilterControllerEvent $event)
{
    // do something
    $event->setController(function() use ($redirectUrl) {
        return new RedirectResponse($redirectUrl);
    });
}

Answer 2

You can't set a response to a FilterControllerEvent object. You need to listen for the kernel.request event because its GetResponseEvent object has the setResponse() method:

$route = 'route_name';

if ($route === $event->getRequest()->get('_route')) {
    return;
}

$url = $this->router->generate($route);
$response = new RedirectResponse($url);
$event->setResponse($response);

Answer 3

More ore less clear way to redirect on 'kernel.controller' event

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.

Symfony 2 - redirect if the user is logged in

Hope it helps.

This ain't no way to go, my friend. You should use a default Symfony Security to cover that for you...
