登录失败后如何返回referer? [英] How to go back to referer after login failure?

问题描述

登录成功有一个参数use_referer: true.对于登录失败，只有 failure_path，这不是我要找的.

第二件事:如何做到这一点并传递错误信息?

第三件事:退出后如何回到referrer?

解决方案

我解决了.

有解决方案:如何在 Symfony 2 中 login_check 后禁用重定向

这是解决我的问题的代码:

headers->get('referer');$request->getSession()->setFlash('error', $exception->getMessage());返回新的重定向响应($referer)；}公共函数 onLogoutSuccess(Request $request){$referer = $request->headers->get('referer');返回新的重定向响应($referer)；}}

处理事件添加到security.yml例如:

form_login:check_path:/access/login_check登录路径:/use_referer: 真failure_handler: authentication_handler登出:路径:/访问/注销目标:/成功处理程序:身份验证处理程序

和 config.yml:

服务:身份验证处理程序:类:AcmeMainBundleHandlerAuthenticationHandler

For login success there is a parameter use_referer: true. For login failure there is only failure_path, which isn't what I'm looking for.

Second thing: How to do that and pass error message?

Third thing: How to go back to referrer after logout?

解决方案

I solved it.

There is solution: How to disable redirection after login_check in Symfony 2

and here is code which solves my problem:

<?php

namespace AcmeMainBundleHandler;

use SymfonyComponentSecurityHttpLogoutLogoutSuccessHandlerInterface;
use SymfonyComponentSecurityHttpAuthenticationAuthenticationFailureHandlerInterface;
use SymfonyComponentSecurityCoreExceptionAuthenticationException;
use SymfonyComponentHttpFoundationRequest;
use SymfonyComponentHttpFoundationRedirectResponse;

class AuthenticationHandler implements AuthenticationFailureHandlerInterface, LogoutSuccessHandlerInterface
{
    public function onAuthenticationFailure(Request $request, AuthenticationException $exception)
    {       
        $referer = $request->headers->get('referer');       
        $request->getSession()->setFlash('error', $exception->getMessage());

        return new RedirectResponse($referer);
    }

    public function onLogoutSuccess(Request $request) 
    {
        $referer = $request->headers->get('referer');
        return new RedirectResponse($referer);
    }
}

to handle events add to security.yml for example:

form_login:
    check_path: /access/login_check
    login_path: /
    use_referer: true
    failure_handler: authentication_handler  
logout:
    path:   /access/logout
    target: /
    success_handler: authentication_handler 

and to config.yml:

services:
    authentication_handler:
        class: AcmeMainBundleHandlerAuthenticationHandler
