ruby-on-rails - Omniauth + Google + Faraday + 背后代理 = 怎么设置代理？

Question

我的生产服务器是Ubuntu 12。
我正在使用Devise + OmniAuth来处理 Google 身份验证。
但是，当 Google 将控件返回给我的应用程序时，我收到一个错误"Network is unreachable"。
我认为这是因为服务器位于代理后面。

这是错误描述：

如何设置 faraday 或 rest_client 以使用代理设置？

提前致谢。

我已经通过使用猴子修补 Oauth2 解决了问题。

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
end

这是一个更好的解决方案：

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, 'login', 'password' {
    scope: ['userinfo.email'],
    access_type: 'online',
    client_options: {connection_opts: {proxy: 'http://myproxy:3128'}}
  }
end
