使用 Rails 4 应用程序在 Heroku 上重定向循环，但不在本地机器上
Redirect Loop on Heroku with Rails 4 App, but not on local machine
App 运行ning Ruby 2.2.2, Rails 4.2.1
当我 运行 我的本地应用程序一切正常。在我进行一些更新之前，在 heroku 上 运行ning 很好。现在我在浏览器中得到的只是 Chrome 中的 "Err too many redirects"，或者 Safari 中的 "Too many redirects..."。即使在我回滚 heroku 上的版本并重置数据库之后，我仍然得到这个。我也清除了两个浏览器上的 cookie 和缓存。还是报错。
我在 heroku 日志中得到了一堆这样的东西：

有人知道是什么原因造成的吗？
我找到了答案。我在 Cloudflare 的网络上。事实证明，如果在他们的 "Crypto" 面板上，如果 SSL 设置为 "flexible" 那么您将收到重定向循环错误。必须将其设置为 "Full".
