Omniauth + Google + Faraday +代理服務器後面=如何設置代理？

我的產品服務器是Ubuntu 12。
我使用Devise + OmniAuth來處理Google身份驗證。
但是，當Google將控件返回給我的應用程序時，出現錯誤「網絡無法訪問」。
我認爲這是因爲服務器在代理之後。Omniauth + Google + Faraday +代理服務器後面=如何設置代理？

這裏的錯誤描述：

正如你可以看到法拉第無法到達的網絡連接。

如何設置法拉第或可能rest_client使用代理設置？

在此先感謝。

我以猴子打補丁的oauth2解決的問題。

require 'faraday' 
module OAuth2 
    # The OAuth2::Client class 
    class Client 
    # The Faraday connection object 
    def connection 
     options[:connection_opts].merge!({:proxy => 'http://10.10.16.8:3128'}) 
     @connection ||= begin 
     conn = Faraday.new(site, options[:connection_opts]) 
     conn.build do |b| 
      options[:connection_build].call(b) 
     end if options[:connection_build] 
     conn 
     end 
    end 
    end

而不是Monakey修補Oauth，你也可以像這裏一樣用一個片段來修補Faraday https://ecarmi.org/writing/faraday-proxy/ – ehc 2014-02-09 22:23:09

放在一個初始化

RestClient.proxy = "http://proxy.example.com/"

你的意思是把它配置/ application.rb中？ – 2012-08-14 12:46:32

是的，你也可以放入config/application.rb，或者如果邏輯比較複雜，就像加載一個yaml文件一樣，你可以創建一個config/initializers/rest_client.rb文件，該文件將保持每個環境的代理設置。 – vvlad 2012-08-14 13:15:07

感謝您的幫助，弗拉德。但不幸的是，它並沒有幫助我。 – 2012-08-14 13:48:12

這裏是一個更好的解決方案：

Rails.application.config.middleware.use OmniAuth::Builder do 
    provider :google_oauth2, 'login', 'password' {
