Php can'；使用自定义用户提供程序时不提交表单

我正在设置一个登录系统，它依赖于对另一个web服务的curl调用来通过登录表单对用户进行身份验证，为此，我按照文档使用maker bundle生成一个自定义用户提供者、一个用户模型、一个SecurityController和一个LoginFormAthenticator。 表单将显示，但不提交，并且不会给出任何错误，以帮助我进行调试

根据symfony文档，LoginFormAthenticator的支持方法每次都会在控制器之前调用，事实上，当我在其中写入骰子时，它会显示我在骰子中放入的内容

除此之外，我还尝试在登录操作中手动创建表单，并检查是否提交，但表单没有提交。 3天以来我一直在努力解决这个问题

登录表单

{% extends 'base.html.twig' %}
{% block stylesheets %}
{{ parent() }}
{{ encore_entry_link_tags('login') }}
{% endblock %}
{% block body %}
<form class="form-signin" method="post" action="{{ path('app_login') }}">
{% if error %}
    <div class="alert alert-danger">{{ error.messageKey|trans(error.messageData, 'security') }}</div>
{% endif %}

<h1 class="h3 mb-3 font-weight-normal">Connectez vous</h1>
<label for="inputEmail" class="sr-only">Email</label>
<input type="email" value="" name="email" id="inputEmail" class="form-control" placeholder="Email" required autofocus>
<label for="inputPassword" class="sr-only">Mot de passe</label>
<input type="password" name="password" id="inputPassword" class="form-control" placeholder="Mot de passe" required>

<input type="hidden" name="_csrf_token"
       value="{{ csrf_token('authenticate') }}"
>

    <button class="btn btn-lg btn-primary" type="submit">
    Connexion
    </button>
</form>
{% endblock %}

SecurityController.php

class SecurityController extends AbstractController
{
    /**
     * @param AuthenticationUtils $authenticationUtils
     * @return Response
     * @Route("/login", name="app_login")
     */
    public function login(AuthenticationUtils $authenticationUtils): Response
    {
        // get the login error if there is one
        $error = $authenticationUtils->getLastAuthenticationError();
        // last username entered by the user
        $lastUsername = $authenticationUtils->getLastUsername();

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

用户模型（因为我没有使用条令）

用户提供者

class UserProvider implements UserProviderInterface
{

    public function loadUserByUsername($username)
    {

        // Load a User object from your data source or throw UsernameNotFoundException.
        // The $username argument may not actually be a username:
        // it is whatever value is being returned by the getUsername()
        // method in your User class.
        throw new \Exception('TODO: fill in loadUserByUsername() inside 
         '.__FILE__);
    }


    public function refreshUser(UserInterface $user)
    {
        if (!$user instanceof User) {
            throw new UnsupportedUserException(sprintf('Invalid user class 
            "%s".', get_class($user)));
        }

        // Return a User object after making sure its data is "fresh".
        // Or throw a UsernameNotFoundException if the user no longer exists.
        throw new \Exception('TODO: fill in refreshUser() inside '.__FILE__);
    }

    public function supportsClass($class)
    {
        return User::class === $class;
    }
}

LoginFormAthenticator这个类应该处理登录系统的每个操作

class LoginFormAuthenticator extends AbstractFormLoginAuthenticator
{
    use TargetPathTrait;

    private $urlGenerator;
    private $csrfTokenManager;

    public function __construct(UrlGeneratorInterface $urlGenerator, 
       CsrfTokenManagerInterface $csrfTokenManager)
    {
        $this->urlGenerator = $urlGenerator;
        $this->csrfTokenManager = $csrfTokenManager;
    }

    public function supports(Request $request)
    {

        return 'app_login' === $request->attributes->get('_route')
        && $request->isMethod('POST');
    }

    public function getCredentials(Request $request)
    {

        $credentials = [
            'email' => $request->request->get('email'),
            'password' => $request->request->get('password'),
            'csrf_token' => $request->request->get('_csrf_token'),
        ];
        $request->getSession()->set(
            Security::LAST_USERNAME,
            $credentials['email']
        );

        return $credentials;
    }

    public function getUser($credentials, UserProviderInterface 
       $userProvider)
    {

        $token = new CsrfToken('authenticate', 
        $credentials['csrf_token']);
        if (!$this->csrfTokenManager->isTokenValid($token)) {
            throw new InvalidCsrfTokenException();
        }

        // Load / create our user however you need.
        // You can do this by calling the user provider, or with custom logic here.
        $user = $userProvider->loadUserByUsername($credentials['email']);

        if (!$user) {
            // fail authentication with a custom error
            throw new CustomUserMessageAuthenticationException('Email could not be found.');
        }

        return $user;
    }

    public function checkCredentials($credentials, UserInterface $user)
    {
        // Check the user's password or other credentials and return true or false
        // If there are no credentials to check, you can just return true
        throw new \Exception('TODO: check the credentials inside '.__FILE__);
    }

    public function onAuthenticationSuccess(Request $request, 
      TokenInterface $token, $providerKey)
    {
        if ($targetPath = $this->getTargetPath($request->getSession(), 
         $providerKey)) {
            return new RedirectResponse($targetPath);
        }

        // For example : return new RedirectResponse($this->urlGenerator- 
        >generate('some_route'));
        throw new \Exception('TODO: provide a valid redirect inside 
      '.__FILE__);
    }

    protected function getLoginUrl()
    {
        return $this->urlGenerator->generate('app_login');
    }
}

我解决了它，因为我使用的是网页加密，有一个js文件，我阻止表单提交。我解决了它，因为我使用的是网页加密，有一个js文件，我阻止表单提交。
