php - Symfony2 注销事件监听器问题

Question

我正在努力将审计日志记录添加到 Symfony2 项目，该项目将所有页面加载和发布请求记录到自定义审计表中。该项目使用 Symfony2 的默认注销路由(访问/logout)，它会破坏 session ，然后重定向到/login 路由。

为 onKernelRequest 设置了一个事件监听器，然后将正确的数据写入表中。在 security.yml 文件中，我为注销路由列出了以下内容。

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

除注销事件外，所有页面的审核日志记录都正常工作。注销后，我尝试访问探查器，然后从侧边栏的“最后 10 个”选项中选择“/注销”操作。单击“事件”时，它会列出 kernel.request 的默认 Symfony 事件，例如 DebugHandler 和 ProfileListener，但我的自定义回调显示在“未调用的监听器”选项卡下。

有一个 success_handler 可以添加到 security.yml 文件中，但是我需要一个可以在 session 被销毁之前运行我的事件监听器的方法。有没有办法让现有的监听器在 Symfony 执行注销操作之前也记录注销事件？

挂接到 Symfony 的注销事件的最好方法是实现 LogoutHandlerInterface像这样，

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]

因此，您真正需要做的就是使用 logout 方法从您的 AuditListener 实现 LogoutHandlerInterface，然后注册 handlers 配置中的参数
