Symfony2 注销事件侦听器问题

Symfony2 Logout Event Listener Issue

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 post 请求记录到自定义审计 table 中。该项目使用 Symfony2 的默认注销路由(访问 /logout),它会破坏会话,然后重新定向到 /login 路由。

为 onKernelRequest 设置了一个事件侦听器,然后将正确的数据写入 table。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工作正常。注销后,我尝试访问探查器,然后从侧边栏的 "Last 10" 选项中选择“/logout”操作。单击 "Events" 时,会列出 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 success_handler 可以添加到 security.yml 文件,但是我需要一种方法可以 运行 我的事件侦听器,然后会话被销毁。有没有办法让现有的侦听器在 Symfony 执行注销操作之前也记录注销事件?

        arguments: [@request_stack, @security.token_storage, @security.authorization_checker, @doctrine.orm.entity_manager]

由于我不清楚你们的 Audit logging 服务,我猜,注销事件发生在手边。因此,您应该尝试通过实现另一个实现 LogoutHandlerInterface 并且依赖于您的 Audit logging 服务的 LogoutHandler 服务来调用您的 Audit logging 服务。

在我们看到日志中发生了什么之后,我们可以得到一个清晰的思路。

挂接到 Symfony 的注销事件的最佳方法是像这样实现 LogoutHandlerInterface

事件侦听器:

<?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 方法实现 AuditListener 中的 LogoutHandlerInterface,然后在配置中注册 handlers 参数
