Invalid character found in method name. HTTP method names must be tokens

Gayhub 上下载了一个别人的项目跑着玩，启动成功了，

但是请求 controller 的时候，出现了这种错误：

2018-08-25 17:57:26,673 - Error parsing HTTP request header

这个错误，查了一下发现

是请求头的问题

人家的 application.yml 中配置的地址是

http://localhost:8080

Restlet 默认请求的是

https：xxxxx

恩，就这样
