Symfony3.2 到 symfony4 security.encoder_factory 已弃用错误

Question

我通过创建新的 symfony4 框架并将源代码从 symfony3.2 移动到 symfony4，将我的网站从 Symfony 3.2 更新到了 Symfony 4。

我已经进行了Upgrading Symfony4中提到的更改。我还安装了所有必需的包。现在我可以进行路由并成功地将我的网页显示在显示器上，我面临的问题是登录表单没有工作。

在我的 symfony3.2 版本的登录控制器中，

我使用了 security.encoder_factory 服务

当我在 symfony4 中运行它时，结果是：

The "security.encoder_factory" service or alias has been removed or inlined when the container was compiled. You should either make it public, or stop using the container directly and use dependency injection instead.

我的控制器密码编码是：

public function loginAction(Request $request)
{
    #$defaultEncoder = new MessageDigestPasswordEncoder('bcrypt', true, 5000);
    $defaultEncoder = new MessageDigestPasswordEncoder('bcrypt');

    $encoders = [
        User::class => $defaultEncoder, // Your user class. This line specify you ant sha512 encoder for this user class
        ];

    $encoderFactory = new EncoderFactory($encoders);

    $data = [
        'error' => null,
        '_username' => null,
    ];
    if ($request->isMethod('POST')) {
        $_username = $request->request->get('_username');
        $_password = $request->request->get('_password');

        $data['_username'] = $_username;
        $user = $this->getDoctrine()->getManager()
            ->getRepository("App:User")
            ->findOneBy(array('username' => $_username);
        if (!$user) {
            $data['error']  = 'User-Id does not exist';
            return $this->render(
                'login.html.twig',
                $data
            );
        }

        $encoder = $encoderFactory->getEncoder($user);
        $salt = $user->getSalt();
        #$encoder = $this->encodePassword($_password, $salt);

        if (!$encoder->isPasswordValid($user->getPassword(), $encoder)) {
            $data['error'] = 'User-Id or Password not valid.';
            return $this->render(
                'login.html.twig',
                $data
            );
        } 

        return $this->redirect($this->generateUrl('default__home_page'));
    }

    return $this->render(
        'login.html.twig',
     $data
    );
}

我的编码安全性是：

security:
   encoders:
        App\Entity\User: bcrypt
        App\Security\User\WebserviceUser: bcrypt
        Symfony\Component\Security\Core\User\User: bcrypt

                class: App:User
                property: username

        id: fos_user.user_provider.username_email

        pattern:    ^/s/login$
        http_basic: ~
        provider: fos_userbundle
        user_checker: security.user_checker

        form_login:
            login_path: login_page
            check_path: login_page
            failure_handler: security.authentication.failure_handler
        guard:
            authenticators:
                - App\Security\LoginControllerAuthenticator
        # activate different ways to authenticate

        # http_basic: ~
        # http://symfony.com/doc/current/security.html#a-configuring-how-your-users-will-authenticate

        # form_login: ~
        # http://symfony.com/doc/current/cookbook/security/form_login_setup.html

        logout:
            path:   /logout/
            target: /login/

是否有任何替代方法或服务可以按照上述代码对我的密码进行编码。

错误：

No encoder has been configured for account "App\Entity\User".

提前致谢。

见文档：

https://symfony.com/doc/current/components/security/authentication.html#the-password-encoder-factory

您可以通过这种方式在控制器中获取编码器。

编辑：

这里是一个例子：

    $defaultEncoder = new MessageDigestPasswordEncoder('sha512', true, 5000);

    $encoders = [
      User::class => $defaultEncoder, // Your user class. This line specify you ant sha512 encoder for this user class
    ];

    $encoderFactory = new EncoderFactory($encoders);

    $user = new User('test', null); // The user you want to authenticate

    $password = $encoderFactory->getEncoder($user)->encodePassword('myPassword', 'mySalt');

编辑 2：

你必须在那里定义你的用户类：

$encoders = [
    App\Entity\User::class => $defaultEncoder,
    ];

检查你没有使用 User Symfony 类。
