php – Symfony2注销事件监听器问题

我正在努力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的默认注销路由(访问/注销),该路由会破坏会话,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.注销后,我尝试访问分析器,然后从侧栏中的“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？

        $this->em->persist($log);
        $this->em->flush();
    }
}

services.yml

services:
    audits.audit_listener:
        class: AuditBundle\EventListener\AuditListener
        arguments: [@request_stack, @security.token_storage, @security.authorization_checker, @doctrine.orm.entity_manager]
        tags:
            - { name: kernel.event_listener, event: kernel.request }

解决方法:

挂钩Symfony的注销事件的最好方法是像这样实现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]

编辑：

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