I'm trying to return a permanent (301) redirect response from a event subscriber hooked into the kernel events in Synfony PHP.
My subscriber is as follow:
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\HttpFoundation\RedirectResponse;
class KernelSubscriber implements EventSubscriberInterface {
public function __construct() {
// some stuff here but not relevant for this example
}
public static function getSubscribedEvents(): array {
return [ KernelEvents::REQUEST => 'onRequest' ];
}
public function onRequest(GetResponseEvent $event): void {
// if conditions met
// 301 redirect to some internal or external URL
if(!$event->isMasterRequest()) return;
}
}
If this were a controller I would return $this->redirectToRoute('route')
or something like that but returning from the onRequest
method is in a much different context.
How can I return a response (a redirect, in particular) from this event subscriber?
Should be something like:
$event->setResponse(new RedirectResponse($route));
