无效凭据身份验证问题 symfony 4

Question

从 symfony 4 开始，我想创建一个简单的身份验证表单。我创建了一个 User 类（标识符是电子邮件字段，而不是“用户名”，我创建了一个类控制器并配置了 security.yml 文件。

但是当我转到表单页面并尝试登录（填写电子邮件/密码字段并单击提交按钮）时，我收到错误“凭据无效”。

安全.yaml

        App\Entity\User:

    providers:

        # used to reload user from session & other features (e.g. switch_user)

        app_user_provider:

            entity:

                class: App\Entity\User

                property: email

    firewalls:

        dev:

            pattern: ^/(_(profiler|wdt)|css|images|js)/

            security: false

        main:

            anonymous: true

            guard:

                authenticators:

                    - App\Security\LoginFormAuthenticator

            logout:

                path: /logout

        #ROLE_SUPER_ADMIN: [ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]

    # Easy way to control access for large sections of your site

    # Note: Only the *first* access control that matches will be used

    access_control:

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

        - { path: ^/profile, roles: ROLE_USER }
