Question

我正在努力将审核日志记录添加到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核表中。该项目使用Symfony2的默认注销路由（访问/注销），该路由销毁会话，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，我列出了以下注销路由。

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

审核日志记录适用于除注销事件之外的所有页面。退出后我尝试访问了探查器，然后选择了＆＃39; / logout＆＃39;来自＆＃34;最后10＆＃34;侧栏中的选项。点击＆＃34; Events＆＃34;这列出了kernel.request的默认Symfony事件，例如DebugHandler和ProfileListener，但我的自定义回调显示在＆＃34; Not Called Listeners＆＃34;标签

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会话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侦听器在Symfony执行注销之前记录注销事件？

挂钩Symfony注销事件的最佳方法是像这样实现LogoutHandlerInterface，

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]

修改：

所以你真正需要做的就是使用LogoutHandlerInterface函数实现AuditListener中的logout，然后在配置中注册handlers参数

Answer 2

由于我不清楚您的Audit logging服务，我猜，退出事件是事先发生的。因此，您应该尝试通过实施另一个Audit logging服务来调用LogoutHandler服务，该服务实现LogoutHandlerInterface并依赖于您的Audit logging服务。

在我们看到日志记录中发生了什么后，我们可以得到一个清晰的想法。
