即使启用了“嵌入式浏览器OAuth登录”并指定了回调URL，仍会收到Facebook回调错误

我有一个使用Facebook登录功能的rails（4.2.0）应用程序。主要的宝石是devise（3.4.0）和omniauth-facebook（2.0.0）。我已经在Facebook上注册了该应用程序，并一直在使用其测试应用程序进行开发。Facebook登录功能可在开发环境中使用。

尝试在生产服务器上使用Facebook登录功能时，出现错误，因为“应用程序配置不允许使用URL：应用程序的设置不允许使用一个或多个给定URL。它必须与网站URL或画布URL，或者域必须是该应用程序域之一的子域。”

将在开发ENV被用于测试应用程序设置的详细信息如-

Settings:
  Basic:
    App Domains: 'localhost'
    Website:
      Site URL: 'http://localhost:3000'
  Advanced:
    OAuth Settings:
      Embedded browser OAuth Login: Yes
      Valid OAuth redirect URIs: "http://localhost:3000/users/auth/facebook/callback"

该生产ENV被用于用于注册应用程序设置的详细信息如-

Settings:
  Basic:
    App Domains: 'www.mysite.co'
    Website:
      Site URL: 'http://www.mysite.co'
  Advanced:
    OAuth Settings:
      Embedded browser OAuth Login: Yes
      Valid OAuth redirect URIs: "http://www.mysite.co/users/auth/facebook/callback"

我在secrets.yml中指定了以下内容

development:
  secret_key_base: some_secret_key 
  facebook:
    app_id: test_app_id
    app_secret: test_app_secret
production:
  secret_key_base: some_secret_key 
  facebook:
    app_id: registered_app_id
    app_secret: registered_app_secret

并且一直在设计初始化程序中使用secrets.yml中的凭据作为

# ==> OmniAuth
# Add a new OmniAuth provider. Check the wiki for more information on setting
# up on your models and hooks.
# config.omniauth :github, 'APP_ID', 'APP_SECRET', scope: 'user,public_repo'
require 'omniauth-facebook'
config.omniauth :facebook, Rails.application.secrets.facebook['app_id'], Rails.application.secrets.facebook['app_secret'], scope: ['user_photos', 'email', 'public_profile']

实际域名（涂黑）在任何地方都没有错别字，并且无论在何处使用都相同。

与omniauth相关的route.rb包含为

 cat config/routes.rb 
Rails.application.routes.draw do
  root 'home#index'

  devise_for :users, controllers: { omniauth_callbacks: "users/omniauth_callbacks" }

  # routes related to other controllers
end

路线如下

bundle exec rake routes | grep user

new_user_session GET      /users/sign_in(.:format)                               devise/sessions#new
user_session POST     /users/sign_in(.:format)                               devise/sessions#create
destroy_user_session DELETE   /users/sign_out(.:format)                              devise/sessions#destroy
user_omniauth_authorize GET|POST /users/auth/:provider(.:format)                        users/omniauth_callbacks#passthru {:provider=>/facebook/}
user_omniauth_callback GET|POST /users/auth/:action/callback(.:format)                 users/omniauth_callbacks#:action

The only code related to omniauth in the entire app is as

$ cat app/controllers/users/omniauth_callbacks_controller.rb 

class Users::OmniauthCallbacksController <  Devise::OmniauthCallbacksController
  def facebook
    #You need to implement the method below in your model (e.g. app/models/user.rb)
    @user = User.from_omniauth(request.env["omniauth.auth"])
    if @user.persisted?
      sign_in_and_redirect @user, event: :authentication #this will   throw if @user is not activated
      set_flash_message(:notice, :success, kind: "Facebook") if is_navigational_format?
    else
      session["devise.facebook_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end
end
