Execute function after User Login Symfony 2.3

Question

I am trying to execute a function after user login in FOSUserBundle, in my config.yml I set the service:

services:
    authentication.success.listener:
        class: MyCompany\MyBundle\EventListener\AuthenticationEventListener
        arguments: [@router]
        tags:
            - { name: kernel.event_subscriber }

Then, I create the Listener class with the methods:

<?php

namespace MyCompany\MyBundle\EventListener;

use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;
use FOS\UserBundle\FOSUserEvents;
use FOS\UserBundle\Event\UserEvent;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Cookie as Cookie;

class AuthenticationEventListener implements EventSubscriberInterface
{    
    private $router;

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

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

    public function onAuthenticationSuccess(UserEvent $event)
    {
        //my actions goes here...
    }

}

?>

When I try to login, nothing happens after, I write some wrong code for generate an exception but everything goes well... apparently the function is not being excetuted.

Any help please?

Well, finally after few hours searching and enjoying the Juventus victory over Real Madrid (2-1) I found a solution. My solution consist in modify the 'success_handler' in security.yml and create the event, this is the code:

security:
    ..
    firewalls:
        main: 
        ..
        success_handler: authentication.success.listener

Then in services.yml I declare the service:

services:
    authentication.success.listener:
        class: MyCompany\MyBundle\EventListener\AuthenticationEventListener
        arguments: ['@router', '@security.context', '@service_container']

Then I declare the class/function to listen:

// MyCompany\MyBundle\EventListener\AuthenticationEventListener.php

<?php

namespace MyCompany\MyBundle\EventListener;

use Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Core\SecurityContext;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Router;    

class AuthenticationEventListener implements AuthenticationSuccessHandlerInterface
{    
    protected $router;
    protected $security;
    protected $container;
    protected $em;

    public function __construct(Router $router, SecurityContext $security, $container)
    {
        $this->router = $router;
        $this->security = $security;
        $this->container = $container;
        $this->em = $this->container->get('doctrine')->getEntityManager();
    }

    public function onAuthenticationSuccess(Request $request, TokenInterface $token)
    {
        $response = new Response();
        $response = new RedirectResponse('dashboard');
        return $response;
    }

}

?>

I hope it could be useful for you guys...

Thanks anyways!

Try this code:

public static function getSubscribedEvents()
{
    return array(
        FOSUserEvents::SECURITY_IMPLICIT_LOGIN => array('onAuthenticationnSuccess',0)
    );
}

This should be the syntax liked documented here: http://symfony.com/doc/current/components/event_dispatcher/introduction.html
