 - root 根目录

 - upstreams 代理地址
- pathrewrite 路径重写
+- directives  这里指令针对的是代理请求，有以下几种：
+    - HostSchemas [$target] 代理地址
+    - HeaderOrigin 代理请求时，添加Origin头
+    - Path [/ws] [/] 代理请求时，重写URL路径，用第二个参数替换url中的第一个部分
+    - RemoveCookie [token] 代理请求时，删除cookie中的某些字段

+### 指令系统

+指令系统采用了nginx的指令系统，指令的格式为：
+
+```
+指令名 参数1 参数2 ... 参数n
+```
+指令系统用来对特定的request/response进行处理。目前只支持：
+
+- 返回的response中设置header
+- 反向代理时，修改发送到上游服务器的请求
