在Symfony 2中的login_check之后如何禁用重定向 [英] How to disable redirection after login_check in Symfony 2

问题描述

我需要在登录检查后禁用重定向，因为我仅需要获得登录成功与否的信息.提交/login_check网址后，请提供正确的数据，但请继续重定向到/login(失败时).
/login之后为空.
我正在尝试使用extjs 4设置登录表单，因此我需要通过ajax发布请求进行验证. login_check应该进行身份验证，创建用户会话并返回成功还是失败，但无处转发.

I need to disable redirection after login check, because I need to get only that the login was success or not. After submission /login_check url give me the right data, but keep redirecting to /login (on failure).
/login is blank after that.
I am trying to set up login form using extjs 4 so I need to validate trough an ajax post request. login_check should authenticate, create user session and return whether it was success or failure, but no forwarding anywhere.

我的login.html.twig看起来像:

my login.html.twig looks like:

{% if is_granted("IS_AUTHENTICATED_REMEMBERED") %}
    { success:true }
{% else %}
    { success: false }
{% endif %}

并在security.yml中:

and in security.yml:

firewalls:
    main:
        form_login:
            provider: fos_userbundle
            failure_path:  null
            failure_forward: false

推荐答案

创建身份验证处理程序:

Create an authentication handler:

namespace YourVendor\UserBundle\Handler;

// "use" statements here

class AuthenticationHandler
implements AuthenticationSuccessHandlerInterface,
           AuthenticationFailureHandlerInterface
{
    public function onAuthenticationSuccess(Request $request, TokenInterface $token)
    {
        if ($request->isXmlHttpRequest()) {
            $result = array('success' => true);
            return new Response(json_encode($result));
        } else {
            // Handle non XmlHttp request here
        }
    }

    public function onAuthenticationFailure(Request $request, AuthenticationException $exception)
    {
        if ($request->isXmlHttpRequest()) {
            $result = array('success' => false);
            return new Response(json_encode($result));
        } else {
            // Handle non XmlHttp request here
        }
    }
}

将处理程序注册为服务:

Register the handler as a service:

services:
    authentication_handler:
        class: YourVendor\UserBundle\Handler\AuthenticationHandler

在防火墙中注册服务:

firewalls:
    main:
        form_login:
            success_handler: authentication_handler
            failure_handler: authentication_handler

这是一个粗略的示例，可以为您提供总体思路-您需要自己弄清楚细节.如果您遇到困难并需要进一步说明，请将您的问题放在注释中，我将尝试详细说明该示例.

This is a rough example to give you the general idea — you'll need to figure out the details by yourself. If you're stuck and need further clarifications, put your questions in the comments and I'll try to elaborate the example.
