ruby-on-rails-3 - 从 Omniauth facebook 访问信息

Question

我需要使用omniauth FacebookRuby on Rails 中的用户信息创建一个表。

我必须为使用我系统的所有用户设置一个表。我使用 Facebook 进行登录身份验证，我想从 Facebook 获取名字、姓氏、照片和电子邮件，并将它们存储在本地数据库中，我将链接到许多其他数据库。

Answer 1

您可以从中获取所有信息

data = request.env["omniauth.auth"]

将此行放入控制器中的操作中，变量data将包含您需要的所有信息Hash，您可以轻松获取这些信息。

通过检查 yaml 格式的数据，它看起来像这样
