Symfony 3登录表单无限循环

我的Symfony版本是：3.0.6

我在认证的几个小时内打架 . 我有登录名和密码的表格 .

我的security.yml看起来：

security:

encoders:
    MainListBundle\Entity\User:
        algorithm: bcrypt

providers:
    default:
        entity:
            class: MainListBundle:User
            property: username

firewalls:
    dev:
        pattern: ^/(_(profiler|wdt)|css|images|js)/
        security: false

    my_app:
        pattern:   ^/
        anonymous: ~
        form_login:
            login_path: /login
            check_path: /login_check
            default_target_path: main_list_homepage
        logout:
            path: /logout
            target: main_list_login

如果数据库中不存在用户名，表单可以显示我 . 但是，如果我输入一些密码（也是错误的）我在“check_path”URL上有无限循环 .

登录表单上的字段是正确的：_username和_password . 表单“action”与安全性中的“check_path”相同 .

我做错了什么......这很奇怪，因为一切都像教程一样 .

控制器：

<?php

namespace MainListBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\Security\Core\Security;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Session\Session;

class LoginController extends Controller
{

    public function indexAction(Request $Request)
    {
        $auth = $this->get('security.authentication_utils');
        $error = $auth->getLastAuthenticationError();
        $username = $auth->getLastUserName();

        return $this->render('MainListBundle:Login:login.html.twig', array(
            'loginError' => $error,
            'username' => $username
        ));
    }

使用routing.yml

main_list_sort:
    path:     /MainList/sort/{field}
    defaults: { _controller: MainListBundle:Default:sort }

main_list_search:
    path:     /MainList/search
    defaults: { _controller: MainListBundle:Default:search }

main_list_clear_search:
    path:     /MainList/clearSearch
    defaults: { _controller: MainListBundle:Default:clearSearch }

main_list_pdfGenerateRecordsList:
    path:     /MainList/pdfGenerateRecordsList
    defaults: { _controller: MainListBundle:Default:pdfGenerateRecordsList }

main_list_homepage:
    path:     /MainList/{page}
    defaults: { _controller: MainListBundle:Default:index, page: 1 }

main_list_login:
    path:     /login
    defaults: { _controller: MainListBundle:Login:index }

main_list_login_check:
    path:     /login_check

main_list_logout:
    path:     /logout
    defaults: { _controller: MainListBundle:Login:logout }

main_list_add_users:
    path:     /addusers
    defaults: { _controller: MainListBundle:Login:addUsers }

表格视图：

{% extends "::base.html.twig" %}

{% block menu %}{% endblock %}

{% block content %}

    <center>
        {% if loginError is defined and loginError is not null %}
            <div class="alert alert-danger">{{ loginError.messageKey }}</div>
        {% endif %}

        <form action="{{ path('main_list_login_check') }}" method="POST">
            <table style="width: 600px">
                <tr>
                    <td>Login:</td>
                    <td>
                        <input type="text" name="_username" value="{{ username }}"/>
                    </td>
                </tr>
                <tr>
                    <td>Password:</td>
                    <td>
                        <input type="password" name="_password" value=""/>
                    </td>
                </tr>

                <tr>
                    <td></td>
                    <td>
                        <input type="submit" value="Zaloguj"/>
                    </td>
                </tr>
            </table>
        </form>
    </center>

{% endblock %}
