解决方案

我遇到过同样的情况，没有一个明确的答案. 您正在使用什么宝石进行Google授权?如果您使用的是omniauth-google-oauth2，请使用以下解决方案:

我找到了一个人的帖子，该人遇到了您所要求的部分应用程序完成后遇到的其他问题，您可以在此处找到它-

I have google login feature implemented in my Rails app and now the scenario is to fetch google plus contacts in my app.

There is one Google Plus gem available but i am not sure whether i can fullfill my requirements using that gem.

Whats the best possible solution to this.

解决方案

I've encounter the same situation, nowhere was clear answer. What gem you are using for Google Authorization? If you are using omniauth-google-oauth2 here is the solution:

I've found post of a guy who encounter different problem AFTER part of application you are asking for was done, you may find it here - http://blog.baugues.com/google-calendar-api-oauth2-and-ruby-on-rails

Down to the code, this how you callback function in a controller (after logging in) should looks like:

 def create  #lets say it is session#new controller
omniauth = request.env["omniauth.auth"]
authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid'])
initial_session(omniauth) unless current_user
 client = Google::APIClient.new()
 client.authorization.access_token = omniauth["credentials"]["token"]
 plus = client.discovered_api('plus')
 contacts = client.execute(plus.people.list, :collection => 'visible',
                                           :userId => 'me')
 raise contacts.inspect.to_s
