 2、对流量实时转发,把81端口流量转发到192.168.3.221:80端口

./gor --input-raw :81--output-http="http://192.168.3.221:80"

3、把抓取到的流量以文件的形式存储到磁盘上

./gor --input-raw :8000 --output-file=requests.gor

4、对抓取到的流量进行回放

#流量回放到192.168.3.221:80
./gor --input-file requests.gor --output-http="http://192.168.3.221:80"
#流量回放打印到屏幕上
./gor --input-file requests.gor --output-stdout

5、快速开一个静态服务器

./gor file-server :8000

6、gor的运行参数如下:文章来源地址https://www.toymoban.com/news/detail-657894.html

Gor is a simple http traffic replication tool written in Go. Its main goal is to replay traffic from production servers to staging and dev environments.
