Php FOSFacebookBundle登录后出错控制器必须返回响应（给定null）

我使用的是Symfony FOSUserBundle、SonataUserBundle、FOSFacebookBundle。我已将登录按钮添加到我的应用程序中

我可以使用facebook登录，但登录后页面重定向到demo/secured/login\u check，我得到以下错误

“控制器必须返回响应（给定null）。您是否忘记在控制器中的某个位置添加return语句？”

我已经看过了

但不确定我应该对配置做什么更改

下面是我的安全配置

        main:
            pattern: ^/
            context:             user
            form_login:

我尝试如下更改配置，以避免两个防火墙匹配相同的URL模式

security:
    encoders:
        FOS\UserBundle\Model\UserInterface: sha512

    role_hierarchy:
        ROLE_ADMIN:       [ROLE_USER, ROLE_SONATA_ADMIN]
        ROLE_SUPER_ADMIN: [ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]
        SONATA:
            - ROLE_SONATA_PAGE_ADMIN_PAGE_EDIT  # if you are using acl then this line must be commented

    providers:
        chain_provider:
            chain:
                providers: [fos_userbundle, fo_fos_facebook_provider]      
        fos_userbundle:
            id: fos_user.user_manager
        fo_fos_facebook_provider:
            id: my.facebook.user

    firewalls:
        # Disabling the security for the web debug toolbar, the profiler and Assetic.
        dev:
            pattern:  ^/(_(profiler|wdt)|css|images|js)/
            security: false

        # -> custom firewall for the admin area of the URL
        admin:
            pattern:            /admin(.*)

                check_path:     /admin/login_check
                failure_path:   null
            logout:
                path:           /admin/logout
            anonymous:          true

        main:
            pattern: ^/
            context:             user
            fos_facebook:
                app_url: "http://apps.facebook.com/my-app/"
                server_url: "http://localhost/me/my/symfony/web/app_dev.php/"
                login_path: /login
                check_path: /login_check
                default_target_path: /
                provider: fo_fos_facebook_provider
                redirect_to_facebook_login: false                
            form_login:
                provider:       fos_userbundle

                csrf_provider: form.csrf_provider
            logout:       true
            anonymous:    true

    access_control:
        # URL of FOSUserBundle which need to be available to anonymous users      
        - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }

        # Secured part of the site
        # This config requires being logged for the whole site and having the admin role for the admin part.

        - { path: ^/admin/, role: [ROLE_ADMIN, ROLE_SONATA_ADMIN] }

        - { path: ^/secured/.*, role: [IS_AUTHENTICATED_FULLY] }

    acl:
        connection: default        

但我现在得到了不同的错误，如下所示

---

“InvalidConfigurationException:不允许为路径“security.firewalls”定义新元素。请在一个配置文件中定义此路径的所有元素。”

如giyhub问题所述： 您不能有两个具有相同模式的防火墙：将使用匹配的第一个防火墙，因此您的公共防火墙不能用作主防火墙，因为主防火墙已经是一个包罗万象的防火墙

主模式和公共模式匹配相同的路由。 您可以在这里尝试：

案例：^/主题：/home OK 案例：^/*主题/主页正常

---

因此，您有两个完全匹配相同URL的防火墙。您必须更改公共防火墙或主防火墙的路由规则。

我找到了它，并在此处共享了我的代码

---

它与FOSUserBundle FOSFacebookBundle SonataAdminBundle SonataUserBundle的全面集成。

我删除了公共防火墙，并将fos_facebook合并到主防火墙中。请检查上面的配置。我现在犯了不同的错误。
