Question

我想知道如果用户尝试访问注册页面时，重定向已经登录的用户的最佳方法是什么。

我更喜欢一种方法，它不需要我简单地覆盖注册控制器来实现登录检查＆amp;重定向。

我查看了注册初始化事件，但我不知道如何启动重定向，因为似乎没有办法通过UserEvent类设置事件响应。

我使用以下内容......

namespace Acme\UserBundle\EventSubscriber;

use FOS\UserBundle\Event\GetResponseUserEvent;
use FOS\UserBundle\FOSUserEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;
use Symfony\Component\Security\Core\SecurityContextInterface;

class FOSUserSubscriber implements EventSubscriberInterface
{
    protected $router;

    protected $securityContext;

    public function __construct(
        UrlGeneratorInterface $router,
        SecurityContextInterface $securityContext
    )
    {
        $this->router = $router;
        $this->securityContext = $securityContext;
    }

    public static function getSubscribedEvents()
    {
        return array(
            FOSUserEvents::REGISTRATION_INITIALIZE  => 'forwardToRouteIfUser',
        );
    }

    public function forwardToRouteIfUser(GetResponseUserEvent $event)
    {
        if (!$this->securityContext->isGranted('IS_AUTHENTICATED_REMEMBERED')) {
            return;
        }

        $url = $this->router->generate('acme_the_route_to_redirect_to');

        $response = new RedirectResponse($url);

        $event->setResponse($response);
    }
}

使用

parameters:
    acme_user.subscriber.fos_user.class: 
            Acme\UserBundle\EventSubscriber\FOSUserSubscriber

services:
    acme_user.subscriber.fos_user:
        class: %acme_user.subscriber.fos_user.class%
        arguments:
            - @router
            - @security.context
        tags:
            - { name: kernel.event_subscriber
