nginx-http-monitor's Introduction

nginx-http-monitor

OpenResty
Lua

开发过程中后端与客户端之前接口请求沟通成本过高，双方需要多次确认信息且很可能得到错误的信息，基于该痛点开发了nginx-http-monitor

例如客户端请求如下：

> http :8080/abc\?x\=2\&y\=z a=b c=d

HTTP/1.1 200 OK
Connection: keep-alive
Content-Type: text/html
Date: Fri, 27 Jul 2018 10:37:54 GMT
Server: openresty/1.13.6.1
Transfer-Encoding: chunked
X-Request-Id: e37c31bfb2d7f2c8af42fce8399d72f1

POST /abc x=2&y=z

会在返回头中生成X-Request-Id做为唯一ID，同时nginx日志会记录该HTTP请求的请求体和响应，日志中JSON中包含请求和响应信息
