我有一个Symfony 5.1项目，具有登录功能。
当我使用Symfony CLI命令symfony serve时，localhost上的登录正常。但是当我尝试通过Docker进行相同的登录时，什么也没有发生。
在我的nginx容器的日志中，我可以看到这样的消息：

172.19.0.1 - - [24/Nov/2020:13:31:40 +0000] "POST /login HTTP/1.1" 302 282 "http://localhost:8088/login" "Mozilla/5.0 (Macintosh; Intel Mac OS X 11_0_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.67 Safari/537.36"

这是我的config/packages/security.yaml：

security:
    enable_authenticator_manager: true

    providers:
        users:
            entity:
                class: 'App\Entity\User'

            logout:
                path: app_logout
                # where to redirect after logout
                target: home

    role_hierarchy:
        ROLE_ADMIN: ROLE_USER

    access_control:
        - { path: ^/admin, roles: ROLE_ADMIN }

这是我的docker/nginx/default.conf：

server {
    listen 80;
    index index.php index.html;
    server_name localhost;
    error_log /var/log/nginx/error.log;

    }

    location ~ \.php$ {

    }
}

这是我的docker/php/Dockerfile：

我的src/Security/LoginFormAuthenticator.php：

<?php

namespace App\Security;

...
use App\Entity\User;
...

class LoginFormAuthenticator extends AbstractFormLoginAuthenticator implements PasswordAuthenticatedInterface
{
    use TargetPathTrait;

    public const LOGIN_ROUTE = 'app_login';

    private $entityManager;
    private $urlGenerator;
    private $csrfTokenManager;
    private $passwordEncoder;

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

    public function supports(Request $request)

    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();
        }

        $user = $this->entityManager->getRepository(User::class)->findOneBy(['email' => $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)
    {
        return $this->passwordEncoder->isPasswordValid($user, $credentials['password']);
    }

    public function getPassword($credentials): ?string
    {
        return $credentials['password'];
    }

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

        return new RedirectResponse($this->urlGenerator->generate('home'));
    }

    protected function getLoginUrl()
    {
        return $this->urlGenerator->generate(self::LOGIN_ROUTE);
    }
}

我做错了什么，我的Docker不能识别我的App\Security\LoginFormAuthenticator作为身份验证器？
提前感谢！

它看起来像是表单正在无错误地重定向自己。我猜使用了错误的验证器，但在我的security.yaml文件中，您可以看到正确的保护。
