我正在使用omniauth-oauth2, omniauth-google-oauth2, omniauth-linkedin-oauth2, omniauth-facebook, omniauth-twittergems 对托管在 aws ec2 中的基本 rails 应用程序进行身份验证。Facebook 和 Twitter 身份验证工作正常，但使用 Linkedin 和 google+ 进行身份验证时呈现消息“未找到。身份验证通路”。Facebook 和 Twitter 工作正常。请帮助我解决问题。非常感谢任何帮助。

提前致谢。

谷歌开发者帐户中我的应用程序站点的回调 URL：

   Authorized JavaScript origins : http://ec2-xx-xxx-xx-xx.us-west
   Authorized redirect URIs : ec2-xx-xxx-xx-xx.us-west/users/auth/google/callback

也试过

   ec2-xx-xxx-xx-xx.us-west/users/auth/google_oauth2/callback

在linkedin开发者帐户中我的应用程序站点的回调URL：

      OAuth 2.0 Authorized Redirect URLs:
      ec2-xx-xxx-xx-xx.us-west/users/auth/linkedin/callback
      ec2-xx-xxx-xx-xx.us-west/users/auth/linkedin_oauth2/callback

甚至尝试使用 OAuth 1.0a 默认“接受”重定向 URL：

   ec2-xx-xxx-xx-xx.us-west-/users/auth/linkedin/callback
