OAuth Hwi Bundle，不同的社交网络

Question

我在 Symfony 中进行项目，它为不同的社交网络注册了 HWIOBundle。如果用户输入例如 LinkedIn 和一些时间 GitHub，我在数据库中有两个用户。谁知道怎么做？

Answer 1

如果用户的电子邮件在两个社交帐户中相似，您可以使用电子邮件字段来识别用户。您应该创建用户提供程序类。如果在数据库中找不到提供社交令牌的用户，用户提供者将尝试通过电子邮件查找用户并将指定社交网络的新社交令牌添加到现有用户实体。

代码示例。

services.xml

<service id="app.my_user_provider" class="AppBundle\Security\FOSUBUserProvider">
    <argument type="service" id="user_manager"/>
    <argument type="collection">
      <argument key="facebook">%facebook_id%</argument>
      <argument key="google">%google_id%</argument>
    </argument>
    <argument type="service" id="event_dispatcher"/>
</service>

security.yml，firewall section

    oauth:
        resource_owners:
            facebook: "/login/check-facebook"
            google: "/login/check-google"
        login_path: /login
        failure_path: /login

        oauth_user_provider:
            service: app.my_user_provider
