ruby-on-rails - 为什么 omniauth 初始化两次？

Question

我正在尝试向我的网站添加 Facebook 身份验证。到目前为止，我已经添加了:

Gemfile

gem 'omniauth-facebook', '1.4.0'

配置/初始化程序/omniauth.rb

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, 'XXXXXXXXXXXX', 'XXXXXXXXXXXXXXXXXXX', {:provider_ignores_state => true}
end

config/routes.rb

match '/auth/:provider/callback', :to => 'sessions#create', as: 'callback'

应用程序/ Controller /sessions_controller.rb

class SessionsController < ApplicationController
  def create
    render :text => request.env['omniauth.auth'].inspect
  end
end

我的问题是初始化似乎运行了两次。在 Rails 服务器的日志中，我看到:

(facebook) Callback phase initiated.
(facebook) Callback phase initiated.
(facebook) Authentication failure! invalid_credentials: OAuth2::Error, : 
{"error":{"message":"This authorization code has been used.","type":"OAuthException","code":100}}
(facebook) Authentication failure! invalid_credentials: OAuth2::Error, : 
{"error":{"message":"This authorization code has been used.","type":"OAuthException","code":100}}

当我跑 rake middleware我看到 OmniAuth::Builder两次。任何建议将不胜感激。

如 Richlewis指的是，如果您将 Devise 与 OmniAuth 一起使用，您需要跳过额外的 omniauth.rb 初始值设定项，并在 initializers/devise.rb 中简单地 config.provider "KEY", "SECRET"，然后继续您的实现。
