这是我的代码：

services.yML

app.kernel.modal_injection:
    class: App\UserBundle\EventListener\ModalListener
    tags:
        - { name: kernel.event_listener,event: kernel.response }
    arguments:
        - @security.authorization_checker

ModalListener.PHP

<?PHP
namespace App\UserBundle\EventListener;

use Symfony\@R_126_480@\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\Event\FilterResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\Security\Core\Security;
use Symfony\Component\Security\Core\Authorization\AuthorizationChecker;


class ConnectModalListener implements EventSubscriberInterface
{
    PRotected $securityChecker;

    public function __construct( AuthorizationChecker $securityChecker )
    {
        $this->securityChecker = $securityChecker;
    }

    public function onKernelResponse( FilterResponseEvent $event )
    {
        $response = $event->getResponse();
        $request = $event->getRequest();

        if ( !$event->isMasterRequest() ) {
            return;
        }
        if ( $request->isXMlHttpRequest() ) {
            return;
        }

        if ( $this->securityChecker->isGranted( 'IS_AUTHENTICATED_REMEMBEred' ) ) {
            return;
        }

        // CODE HERE


    }

    public static function getSubscribedEvents()
    {
        return array(
            KernelEvents::RESPONSE => array( 'onKernelResponse',0 ),);
    }
}

我的问题是,在检查用户IS_AUTHENTICATED_REMEMBER是否在我的页面上提供css和js文件时出现错误500(意味着没有js或css).有没有办法收费？最终在那些上过滤kernel.response事件？
