Symfony2注销事件监听器问题

Question

我正在将审计日志记录添加到Symfony2项目，该项目记录所有页面加载并将请求发布到自定义审计表中。该项目使用Symfony2（访问/注销）的默认注销路由，这会破坏会话，然后重新定向到/ login路由。

有一个事件监听器为onKernelRequest设置，然后将正确的数据写入表中。在security.yml文件中，我列出了以下注销路由。

security: 
    firewalls: 
     main: 
      logout: 
       path: /logout 
       target: /login 

对于除注销事件以外的所有页面，审计日志记录工作正常。注销后，我尝试访问分析器，然后从侧边栏的“最后10个”选项中选择“/注销”操作。当点击“事件”时，它列出了kernel.request的默认Symfony事件，例如DebugHandler和ProfileListener，但是我的自定义回调显示在“Not Called Listeners”选项卡下。

有一个可以添加到security.yml文件中的success_handler，但是我需要一个可以在会话销毁之前运行我的事件侦听器的方法。有没有办法让现有的监听器在Symfony操作注销之前记录注销事件？

Answer 1

由于我不在你Audit logging服务清楚，我猜，注销事件手之前发生。因此，您应尝试通过实施另一个LogoutHandler服务来调用您的Audit logging服务，该服务实施LogoutHandlerInterface并依赖于您的Audit logging服务。

当我们看到记录中发生了什么后，我们可以清楚地知道。

Answer 2

挂接到的Symfony的注销事件的最好办法是实施LogoutHandlerInterface这样，

事件监听器：

<?php 

namespace AppBundle\EventListener; 

use Symfony\Component\HttpFoundation\Request; 
use Symfony\Component\HttpFoundation\Response; 
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface; 
use Symfony\Component\Security\Http\Logout\LogoutHandlerInterface; 

class MyListener implements LogoutHandlerInterface { 

    public function logout(Request $Request, Response $Response, TokenInterface $Token) { 

     // Your handling here 

     } 

} 

配置：

services: 
    appbundle_mylistener: 
     class: AppBundle\EventListener\MyListener 

security: 
    firewalls: 
     main: 
      logout: 
       handlers: [appbundle_mylistener]

所以， OU真正需要做的，是与logout功能实现从AuditListener的LogoutHandlerInterface，然后登记在配置
