nginx实时流量拷贝ngx_http_mirror

nginx实时流量拷贝ngx_http_mirror_module

参考：
Module ngx_http_mirror_module
Nginx流量拷贝ngx_http_mirror_module模块使用方法详解

ngx_http_mirror_module用于实时流量拷贝

请求一个接口，想实时拷贝这个请求转发到自己的服务上，可以使用ngx_http_mirror_module模块。
官网好像就两个指令，

mirror
mirror_request_body

在这里插入图片描述

例子

案例流程：

curl client -> 本地nginx -> 测试服务（这里用的是一个nginx模拟的服务）

~/data/nginx/web/conf/ cat default.conf upstream kevin-mirror2 {server 192.168.52.133:80;   # 这个实际上是另一个nginx
}
server {listen       80;listen  [::]:80;server_name  localhost;access_log  /var/log/nginx/host.access.log  main;location ~* \.(jpg|JPG|PNG|jpeg|png|gif)$ {root /static;}location / {
