带Rails的omniauth:获取Facebook用户信息 [英] omniauth with rails: get facebook user's information

问题描述

在身份验证过程的回调中，我要做:
auth_hash = request.env['omniauth.auth']

in the callback of the authentication process I do:
auth_hash = request.env['omniauth.auth']

然后，我要提取用户ID，但是是否可以同时获取用户名和电子邮件地址?

and then, I'm extracting the user id, but is it possible in the same time getting the user's name and email address?

推荐答案

您需要首先从request.env ["omniauth.auth"]

You need to first get the raw data from request.env["omniauth.auth"]

  data = request.env["omniauth.auth"].extra.raw_info 
  username = data.first_name 
  email  = data.email
