一个简单的运维调试工具，此工具旨在帮助运维定位真实ip，在一些复杂的场景中，一个域名要经过很多层转发才会到达后端服务，这个过程中ip地址因为转发会出现后端服务获取到的是内网ip的情况。

同时支持自定义返回状态码，通过?http_code=500指定返回状态码，模拟后端服务异常情况下不同网关对于错误状态的处理和Header获取情况。

浏览器直接访问ip:port，会返回如下json ,根据返回信息开发运维人员能够更好的调试获取的Header信息，以此来获取真实IP 程序日志和返回的json信息中均会显示RequestJson和RequestPostForm信息，以此来调试程序提交中参数的正确提交等问题调试

• Client-Ip: 程序获取到的IP
• Header: 获取到的Header 头信息
• RealIp: 通过X-Forwarded-For X-Original-Forwarded-For ，由程序获取到真实IP
• Method: 请求方法
• RequestURI: 请求url
• RequestPostForm 程序获取到的表单参数
• RequestJson 程序获取到的json提交

返回html页面

http://127.0.0.1:8080/?format=html

指定返回状态码，测试不同状态码下网关处理逻辑

curl "http://127.0.0.1:8080?http_code=500" -I
curl "http://127.0.0.1:8080?http_code=400" -I

• http_code 任意http状态码值

启动

./app -port :8081

docker运行

docker run -itd -p 8087:8080 typ431127/getip:0.2.4

返回结果中显示hostname,容器中调试开启

docker run -itd -p 8087:8080 typ431127/getip:0.2.4 -hostname
