我有一个运行在puma
Web服务器上的Rails 4.1应用程序。我使用nginx作为代理服务器。几天前一切正常。我更新了我的应用程序,突然一些POST
请求开始以相同的URL重定向为GET
请求。我尝试回滚到之前工作的版本,但没有成功。
我发现了非常有趣的行为。我用curl
测试了我的API。
- 如果我对URL
http://myapp.com/tasks/easy_task/calculate/
进行POST
请求,则会将其重定向为相同的URL,但是以GET
请求。 - 然后我对
http://myapp.com/
进行POST
请求,返回404 - 然后我对
http://myapp.com/tasks
进行POST
请求,返回404 - 然后我对
http://myapp.com/tasks/easy_task
进行POST
请求,返回404 - 然后我对
http://myapp.com/tasks/easy_task/calculate
进行POST
请求,返回200。太好了!
当我使用Chrome的应用程序Postman
时也发生了同样的情况。首先是重定向,但是在完成前几个步骤后它可以正常工作。
我在我的另一个应用程序中使用这个应用。我使用RestClient
发出HTTP请求。当我尝试发起POST
请求时,它会引发异常RestClient::MovedPermanently (301 Moved Permanently)
。
- 我将
nginx
重新安装为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,但是没有一个能够给我解决这个问题的线索。我希望您能帮助我解决这个问题。提前致谢!
类似的问题: - POST request turns into GET request - POST request mysteriously turn into GET request
