事件FOSUserBundle Symfony2注册和登录

Question

我正在尝试在FOSUserBundle上实现事件

<?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();
    }
}

而我的服务

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'}

但我有问题.当我没有登录时,会getSubscribedEvents()被呼叫,但不是onSecurityImplicitLogin(UserEvent $event)

另一个问题是登记.发生以下错误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

如果我评论这一行,我得到了相同的错误 onRegistrationCompleted(FilterUserResponseEvent $event)

编辑

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

两点:

1. 在服务定义- { name: 'kernel.event_subscriber'}就足够了,没有事件输入.这是订阅者和监听者之间的区别.侦听器只能侦听一个事件,在服务定义中定义了槽event和method参数.订阅者可以监听通过该方法定义的多个事件,getSubscribedEvents()因此不需要服务定义中的其他参数.

2. 第二点,您是对事件类(UserEvent和FilterUserResponseEvent)的类型提示,但您从未导入它们,因此PHP假定它们位于相同的命名空间中(如错误消息中所述).

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