Symfony2: After successful login event, perform set of actions
提问by jbsound
I need to perform a set of actions after a user successfully logs in. This includes loading data from the database and storing it in the session.
我需要在用户成功登录后执行一组操作。这包括从数据库加载数据并将其存储在会话中。
What is the best approach to implementing this?
实现这一点的最佳方法是什么？

You can add a listener to the security.interactive_loginevent.
您可以向security.interactive_login事件添加侦听器。
attach your listener like so. In this example I also pass the security context and session as dependencies.
像这样附加你的听众。在此示例中，我还将安全上下文和会话作为依赖项传递。
Note:SecurityContext is deprecated as of Symfony 2.6. Please refer to http://symfony.com/blog/new-in-symfony-2-6-security-component-improvements
注意：SecurityContext 从 Symfony 2.6 开始被弃用。请参考 http://symfony.com/blog/new-in-symfony-2-6-security-component-improvements
parameters:
# ...
account.security_listener.class: Company\AccountBundle\Listener\SecurityListener
services:
# ...
account.security_listener:
class: %account.security_listener.class%
arguments: ['@security.context', '@session']
tags:
- { name: kernel.event_listener, event: security.interactive_login, method: onSecurityInteractiveLogin }
and in your listener you can store whatever you want on the session. In this case I set the users timezone.
在您的听众中，您可以在会话中存储您想要的任何内容。在这种情况下，我设置了用户时区。
<?php
namespace Company\AccountBundle\Listener;
use Symfony\Component\Security\Core\SecurityContextInterface;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;
class SecurityListener
{
public function __construct(SecurityContextInterface $security, Session $session)
{
$this->security = $security;
$this->session = $session;
}
public function onSecurityInteractiveLogin(InteractiveLoginEvent $event)
{
$timezone = $this->security->getToken()->getUser()->getTimezone();
if (empty($timezone)) {
$timezone = 'UTC';
}
$this->session->set('timezone', $timezone);
}
}

You can even fetch the user instance from the event itself, no need to inject the token storage!
您甚至可以从事件本身获取用户实例，无需注入令牌存储！
public function onSecurityInteractiveLogin(InteractiveLoginEvent $event)
{
$event->getAuthenticationToken()->getUser()
}
