我有 Rails 4.1 应用程序运行puma网络服务器。我使用 nginx 作为代理服务器。几天前，一切都进展顺利。我更新了我的应用程序，突然有些POST请求开始重定向到相同的网址，但作为GET要求。我尝试回滚到以前的工作版本，但没有成功。
我发现非常有趣的行为。我测试了我的 APIcurl.
- 如果我这样做了
POST请求到urlhttp://myapp.com/tasks/easy_task/calculate/它重定向到相同的网址
但作为GET要求。
- 然后我做了
POST请求http://myapp.com/，返回404
- 然后我做了
POST请求http://myapp.com/tasks，返回404
- 然后我做了
POST请求http://myapp.com/tasks/easy_task，返回404
- 然后我做了
POST请求http://myapp.com/tasks/easy_task/calculate，返回 200。耶！
当我使用chrome的应用程序时也发生了同样的事情Postman。首先它重定向，但经过前面的步骤后它运行良好。
我在其他应用程序中使用此应用程序。我用RestClient发出 http 请求。当我尝试制作时POST请求它引发异常RestClient::MovedPermanently (301 Moved Permanently).
- 我重新安装了
nginx to 1.7.3.
- 重启服务器（虚拟机）
- 重新部署我的应用程序，部署以前的版本
- 没有成功:(
我在 stackoverflow 上发现了类似的问题，但没有一个给我解决这个问题的线索。我希望你能帮助我解决这个问题。提前致谢！
