Question

提交登录表单后出现以下错误：

Authentication request could not be processed due to a system problem.

我写了以下代码：

用户控制器

/**
     * @Route("/login", name="login")
     */
    public function login(Request $request, AuthenticationUtils $authenticationUtils)
    {
        $error = $authenticationUtils->getLastAuthenticationError();

        // last username entered by the user
        $lastUsername = $authenticationUtils->getLastUsername();

        return $this->render('user/login.html.twig', array(
            'last_username' => $lastUsername,
            'error'         => $error,
        ));
    }

Login.html.twig：

{% extends 'base.html.twig' %}


{% block body %}
{% if error %}
    <div>{{ error.messageKey|trans(error.messageData, 'security') }}</div>
{% endif %}

<form action="{{ path('login') }}" method="post">
    <label for="username">Username:</label>
    <input type="text" id="username" name="_username" value="{{ last_username }}" />

    <label for="password">Password:</label>
    <input type="password" id="password" name="_password" />

    {#
        If you want to control the URL the user
        is redirected to on success (more details below)
        <input type="hidden" name="_target_path" value="/account" />
    #}

    <button type="submit">login</button>
</form>

{% endblock %}

在分析器中，我找不到任何记录告诉我如何解决此问题的日志。信息和信息中只有两个日志。错误：

匹配路线＆＃34;登录＆＃34;。并使用匿名令牌填充TokenStorage。

有人可以帮我解决这个问题吗？
