Facebook 身份验证在 rails 3.2.3 上引发错误

Question

我设置了一个 rails 应用程序（3.2.3 [设计 3.4.1，omniauth facebook 2.0.0，omniauth 1.2.2]）以将 facebook 用作authenticator 并且我在尝试登录时遇到了这个问题。问题是，它甚至没有到达我的代码（控制器）。你有什么想法吗？

奇怪的是，当我在主机上设置 127.0.0.1 mydomain.com 并浏览到 mydomain.com:3000 时，它起作用了！虽然在本地我使用 http 而不是 https 像生产。

Started GET "/users/auth/facebook" for x.x.x.x at 2015-02-12 00:45:05 +0000
Started GET "/users/auth/facebook/callback?code=xxxx" for 127.0.0.1 at 2015-02-12 00:45:05 +0000

URI::InvalidURIError (the scheme http does not accept registry part: app_server (or bad hostname?)):

Answer 1

原来是nginx代理的问题，我忘记转发给定位置的Host header。我刚刚设置了 header 主机，一切正常。

proxy_set_header Host 'example.com';
