在ROR应用程序中使用Facebook和OAuth登录时出错

伙计们，我放弃了。 我创建Rails应用程序，并希望登录Facebook。 我看看railscast，阅读一些教程以及关于stackoverflow的20多个问题…但我仍然无法在我的网站上使用fb登录..所以，请帮助我解决这个问题…

的Gemfile

gem 'omniauth-facebook' gem 'koala', '~> 1.10.0rc' 

配置/初始化/ omniauth.rb

 OmniAuth.config.logger = Rails.logger Rails.application.config.middleware.use OmniAuth::Builder do provider :facebook, Rails.application.secrets['APP_ID'], Rails.application.secrets['APP_SECRET'], { scope: 'user_about_me' } end 

index.html.slim

 h2 Welcome = link_to 'Login with Facebook', '/auth/facebook' 

Facebook – >开发者 – > MyApp – > Settigns Basic：

设置高级

在“使用Facebook登录”链接并在popap中确认后，我有错误：

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的URL。 它必须与网站URL或Canvas URL匹配，或者域必须是App域之一的子域。

有人可以解释我，Facebook或我的手有什么问题吗？

更新：好的，另一个错误：当Valid OAuth redirect URIs设置为http://localhost:3000/auth/facebook/callback/ ，FACEBOOK响应错误Given URL is not permitted by the Application configuration: One or more of the given URLs is not permitted by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains. Given URL is not permitted by the Application configuration: One or more of the given URLs is not permitted by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.

但是当Valid OAuth redirect URIs设置为http://localhost:3000/auth/facebook/callback （末尾没有’/’）时，我遇到OAuth2错误： OAuth2::Error : {"error":{"message":"Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request","type":"OAuthException","code":100,"fbtrace_id":"EYOCCnhlcFv"}}

它目前已被打破。 现在有一个pr out来修复gem。
