Symfony3错误登录表单

Question

我目前正在创建一个Symfony3应用程序，我无法使我的登录表单工作；我遵循以下步骤：

• http://symfony.com/doc/current/cookbook/security/form_login_setup.html
• http://symfony.com/doc/current/cookbook/doctrine/registration_form.html

注册系统正在工作，但我无法登录。我想知道我的代码是否有问题：

错误出现在Symfony教程的security.yml中security.yml如下所示：

# app/config/security.yml
security:
    # ...

    firewalls:
        main:
            anonymous: ~
            form_login:
                login_path: login
                check_path: login

但是登录路径和检查路径是错误的；您应该将路线与/一起使用，因此路线必须如下所示：

# app/config/security.yml
security:
    # ...

    firewalls:
        main:
            anonymous: ~
            form_login:
                login_path: /login
                check_path: /login

我不知道这是否是一个常见的错误，但我希望这能帮助到某人。
