Events FOSUserBundle Symfony2 on register and login

Question

I'm trying to implement events on FOSUserBundle

<?php
namespace EasyApp\UserBundle\Service;

use Symfony\Component\Security\Core\SecurityContext;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Doctrine\Bundle\DoctrineBundle\Registry as Doctrine; 
use EasyApp\UserBundle\Entity\UserLogin;
use FOS\UserBundle\FOSUserEvents;
use FOS\UserBundle\Event\FormEvent;
use FOS\UserBundle\FOSUserBundle;


class LoginManager implements EventSubscriberInterface
{
    /** @var \Symfony\Component\Security\Core\SecurityContext */
    private $securityContext;

    /** @var \Doctrine\ORM\EntityManager */
    private $em;

    /**
     * Constructor
     *
     * @param SecurityContext $securityContext
     * @param Doctrine        $doctrine
     */
    public function __construct(SecurityContext $securityContext, Doctrine $doctrine)
    {
        $this->securityContext = $securityContext;
        $this->em = $doctrine->getEntityManager();
    }

    /**
     * {@inheritDoc}
     */
    public static function getSubscribedEvents()
    {
        return array(
                FOSUserEvents::SECURITY_IMPLICIT_LOGIN => 'onSecurityImplicitLogin',
                FOSUserEvents::REGISTRATION_COMPLETED=> 'onRegistrationCompleted'
        );
    }

    public function onSecurityImplicitLogin(UserEvent $event)
    {
        die;
        $user = $event->getAuthenticationToken()->getUser();
        $request = $event->getRequest();

        if ($this->securityContext->isGranted('IS_AUTHENTICATED_FULLY')) {
            // user has just logged in
            $this->saveLogin($request, $user);
        }
    }

    public function onRegistrationCompleted(FilterUserResponseEvent $event){
        $user = $event->getAuthenticationToken()->getUser();
        $request = $event->getRequest();
        saveLogin($request, $user);
    }

    public function saveLogin($request, $user){
        $login = new UserLogin();
        $login->setIp($request->getClientIp());
        $login->setUser($user);

        $this->em->persist($login);
        $this->em->flush();
    }
}

And my service

services:
    user_login_manager:
        class: 'EasyApp\UserBundle\Service\LoginManager'
        arguments: ['@security.context', '@doctrine']
        tags:
            - { name: 'kernel.event_subscriber', event: 'fos_user.security.interactive_login'}
            - { name: 'kernel.event_subscriber', event: 'fos_user.registration.completed'}

But I have problems. When I login nothing happen, the getSubscribedEvents() is called but not onSecurityImplicitLogin(UserEvent $event)

And the other problem is on register. Following error occurs on onSecurityImplicitLogin(UserEvent $event)

Catchable Fatal Error: Argument 1 passed to EasyApp\UserBundle\Service\LoginManager::onSecurityImplicitLogin() must be an instance of EasyApp\UserBundle\Service\UserEvent, instance of FOS\UserBundle\Event\UserEvent given in /Users/antoine/Documents/projects/easyApp/application/src/EasyApp/UserBundle/Service/LoginManager.php line 46

and if I comment this line I got the same error on onRegistrationCompleted(FilterUserResponseEvent $event)

Edit

services:
    user_login_manager:
        class: 'EasyApp\UserBundle\Service\LoginManager'
        arguments: ['@security.context', '@doctrine']
        tags:
            - { name: 'kernel.event_subscriber'}
            - { name: 'kernel.event_listener', event: 'security.interactive_login' }

Answer 1

Two points:

1. In the service definition - { name: 'kernel.event_subscriber'} is enough, no event entry. This the difference between subscriber and listener. A listener can only listen to one event, defined trough event and method params in the service definition. A subscriber can listen to multiple events, defined trough the method getSubscribedEvents(), so no further params in the service definition needed.

2. Second point, you are type hinting against the event classes (UserEvent andFilterUserResponseEvent), but you never imported them, so PHP assumes them in the same namespace (as said in the error message).

   use FOS\UserBundle\Event\UserEvent;
   use FOS\UserBundle\Event\FilterUserResponseEvent;
