Question

基本上，我试图在Symfony中使用FOSUserBundle实现FOSFacebookBundle。我关注了FOSFacebookBundle的2.0分支的自述文件，但是现在我仍然坚持这个错误。有什么想法吗？

错误：

Catchable Fatal Error: Argument 2 passed to FOS\FacebookBundle\Security\Authentication\Provider\FacebookProvider::__construct()
must implement interface Symfony\Component\Security\Core\User\UserProviderInterface,
instance of FOS\FacebookBundle\Security\Authentication\Provider\FacebookProvider given,

and defined in /var/www/Symfony/vendor/bundles/FOS/FacebookBundle/Security/Authentication/Provider/FacebookProvider.php line 37

    alias:  facebook
    app_id: %projectname_bundle.facebook.app_id%
    secret: %projectname_bundle.facebook.secret%
    cookie: true
    permissions: %projectname_bundle.facebook.perms%

MyUserManager.php（已修改，因此我可以使用电子邮件地址作为FOSUserbundle的用户名。不知道它是否真的相关，但错误告诉我第二个问题传递给FacebookProvider构造函数的参数，该参数应该是UserManager）：

<?php

namespace ProjectName\UserBundle\Model;

use FOS\UserBundle\Entity\UserManager;
use Symfony\Component\Security\Core\Exception\UsernameNotFoundException;

class MyUserManager extends UserManager
{
    public function loadUserByUsername($username)
    {
        $user = $this->findUserByUsernameOrEmail($username);

        if (!$user) {
            throw new UsernameNotFoundException(sprintf('No user with email "%s" was found.', $username));
        }

        return $user;
    }
}

Answer 1

FacebookProvider （ FOS \ FacebookBundle \ Security \ Authentication \ Provider \ FacebookProvider ）实现 AuthenticationProviderInterface 而非 UserProviderInterface 。它不是用户提供商，而是身份验证提供商，fos_facebook需要用户提供商。

因此，您应该定义一个自定义用户提供程序：它已解释为here (Installation step 6. and in "Example Custom User Provider using the FOS\UserBundle")

1）security.yml

添加：

# application/config/config.yml
security:
    providers:
        ...
        # choose the provider name freely
        my_fos_facebook_provider:
            id: my.facebook.user
        ...
firewalls:
    main:
        pattern:      .*
        fos_facebook:
            ...
            provider: my_fos_facebook_provider
            ...

2）config.yml

添加：

services:
    my.facebook.user:
        class: Acme\MyBundle\Security\User\Provider\FacebookProvider
        arguments:
            facebook: "@fos_facebook.api"
            userManager: "@fos_user.user_manager"
            validator: "@validator"
            container: "@service_container"

3）FacebookProvider.php

在Acme / MyBundle / Security / User / Provider /

中创建一个文件FacebookProvider.php

Readme.md

末尾的代码

4）User.php

通过添加一些与FB相关的字段（Id，名字，姓氏等）来编辑您的用户实体
