使用oauth2 GoogleOAuth2gem从auth散列检索first_name和last_name

Question

我有一个使用omniauth-google-oauth2 gem的rails 4.2.7应用程序设置，我想从auth散列中检索first_name和last_name。

我可以通过修改omniauth-facebook创业板来实现这一点，devise.rb如下所示，

devise.rb

# Omniauth / Oauth2 settings
  callback_url = if Rails.env == "development"
   ENV['FB_CALLBACK']
  else
    ENV['FB_CALLBACK_PROD']
  end

  config.omniauth :facebook, ENV['FACEBOOK_KEY'], ENV['FACEBOOK_SECRET'], callback_url: callback_url,
   :scope => 'email',
   :info_fields => 'email, first_name, last_name'
  # Google - OmniAuth
  require 'omniauth-google-oauth2'
  config.omniauth :google_oauth2, ENV["GOOGLE_CLIENT_ID"], ENV["GOOGLE_CLIENT_SECRET"]

但是，我似乎不知道如何使用first_name / last_name检索omniauth-google-oauth2。任何帮助都将不胜感激。

@克里斯，在你的回调控制器动作中，

auth = request.env['omniauth.auth']

request.env['omniauth.auth']将包含用户第四次会话的散列，其中基本用户信息将在info中持久化，即auth["info"]

auth
====
{
.....
"info"=>
  {"name"=>"Username",
   "email"=>"Useremail",
   "first_name"=>"firstname",
   "last_name"=>"lastname",
   "image"=> "image_url",
   "urls"=>{"Google"=>"https://plus.google.com/xxxxxxxxxxxxxxxxx"}
  }
....
}
