omniauth（自定义策略）/门卫的法拉第超时错误

我目前正在跟随这个railscast并且因为我的具体情况在omniauth的回调中遇到了法拉第超时错误 .

目前我正在使用rails应用程序作为API和骨干作为javascript前端（在同一个应用程序中）

我决定使用OAuth锁定API并为Omniauth提供自定义策略以作为客户端访问API以及门卫来处理授权逻辑

module OmniAuth
      module Strategies
        class Twiddle < OmniAuth::Strategies::OAuth2
          option :name, :twiddle

          option :client_options, {
            site: "http://localhost:3001",
            authorize_path: "/oauth/authorize"
          }

          uid do
            raw_info["id"]
          end

          info do
            { 
              firstName: raw_info["firstName"],
              lastName: raw_info["lastName"], 
              email: raw_info["email"]
            }
          end

          def raw_info
            @raw_info ||= access_token.get('/api/v1/user').parsed
          end
        end
      end
    end

我包括这样的自定义策略：

require File.expand_path('lib/omniauth/strategies/twiddle', Rails.root)

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :twiddle, id, secret # Omitting the actual ones for obvious reasons
end

我目前正在使用这些宝石

# OAuth 
gem 'oauth2'
gem 'omniauth'
gem 'omniauth-oauth2'
gem 'omniauth-facebook'
gem 'doorkeeper'

这是我验证的地方，并试图检索正确的访问令牌（以及我卡住的地方）

def loginParse
    if ( user = User.authenticate( params[:email], params[:password] ) ) 
      session[:user_id] = user.id
      redirect_to '/auth/twiddle/' 
    else 
      render :controller => "authentication", :action => "loginIndex", :notice => "Incorrect credentials" 
    end
  end

这是来自routes.rb的路由

# Oauth urls
  match '/auth/twiddle/callback', to: "authentication#connectAPI"
  match "/auth/facebook/callback", to: "authentication#loginSocialMedia"

应用程序永远无法呈现connectAPI操作，此时完全陷入困境（由服务器日志指定）

User Load (0.4ms)  SELECT `users`.* FROM `users` WHERE `users`.`id` = 1 LIMIT 1
  Doorkeeper::Application Load (0.2ms)  SELECT `oauth_applications`.* FROM `oauth_applications` WHERE `oauth_applications`.`uid` = '' LIMIT 1
  CACHE (0.0ms)  SELECT `users`.* FROM `users` WHERE `users`.`id` = 1 LIMIT 1
  Doorkeeper::AccessToken Load (0.3ms)  SELECT `oauth_access_tokens`.* FROM `oauth_access_tokens` WHERE `oauth_access_tokens`.`revoked_at` IS NULL AND `oauth_access_tokens`.`application_id` = 1 AND `oauth_access_tokens`.`resource_owner_id` = 1 ORDER BY created_at desc LIMIT 1
   (0.1ms)  BEGIN

   (1.4ms)  COMMIT
Redirected to http://localhost:3001/auth/twiddle/callback?code=a
Completed 302 Found in 12ms (ActiveRecord: 3.7ms)
(twiddle) Callback phase initiated.

日志中省略了许多uid /重要信息 .

最后给出了这个错误：

Faraday::Error::TimeoutError (Timeout::Error):

我希望我对这个问题的解释是彻底的 .

我不知道为什么应用程序似乎在omniauth的回调启动部分冻结 . 我已经尝试更新bundler，因为其他一些stackoverflow问题指出了我，但它不起作用 .

也许我对OAuth2的理解有点模糊 .

如果有人可以帮助我，我将非常感激
