gor工具http流量复制、流量回放，生产运维生气
gor是一款流量复制回放工具，gor工具的官网：https://goreplay.org/
1、对某个端口的http流量进行打印
./gor --input-raw :8000 --output-stdout2、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.gor4、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-stdout5、快速开一个静态服务器
./gor file-server :80006、gor的运行参数如下：
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.

Current Version: v1.3.0
-copy-buffer-size value
Set the buffer size for an individual request (default 5MB)
-cpuprofile string
write cpu profile to file
-exit-after duration
exit after specified duration
-http-allow-header value
A regexp to match a specific header against. Requests with non-matching headers will be dropped:
gor --input-raw :8080 --output-http staging.com --http-allow-header api-version:^v1
-http-allow-method value
Whitelist of HTTP methods to replay. Anything else will be dropped:
gor --input-raw :8080 --output-http staging.com --http-allow-method GET --http-allow-method OPTIONS
-http-allow-url value
A regexp to match requests against. Filter get matched against full url with domain. Anything else will be dropped:
gor --input-raw :8080 --output-http staging.com --http-allow-url ^www.
-http-basic-auth-filter value
A regexp to match the decoded basic auth string against. Requests with non-matching headers will be dropped:
gor --input-raw :8080 --output-http staging.com --http-basic-auth-filter "^customer[0-9].*"
-http-disallow-header value
A regexp to match a specific header against. Requests with matching headers will be dropped:
gor --input-raw :8080 --output-http staging.com --http-disallow-header "User-Agent: Replayed by Gor"
-http-disallow-url value
A regexp to match requests against. Filter get matched against full url with domain. Anything else will be forwarded:
gor --input-raw :8080 --output-http staging.com --http-disallow-url ^www.
-http-header-limiter value
Takes a fraction of requests, consistently taking or rejecting a request based on the FNV32-1A hash of a specific header:
gor --input-raw :8080 --output-http staging.com --http-header-limiter user-id:25%
-http-original-host
Normally gor replaces the Host http header with the host supplied with --output-http. This option disables that behavior, preserving the original Host header.
-http-param-limiter value
Takes a fraction of requests, consistently taking or rejecting a request based on the FNV32-1A hash of a specific GET param:
gor --input-raw :8080 --output-http staging.com --http-param-limiter user_id:25%
-http-pprof :8181
Enable profiling. Starts http server on specified port, exposing special /debug/pprof endpoint. Example: :8181
-http-rewrite-header value
Rewrite the request header based on a mapping:
gor --input-raw :8080 --output-http staging.com --http-rewrite-header Host: (.*).example.com,$1.beta.example.com

Rewrite the request url based on a mapping:
gor --input-raw :8080 --output-http staging.com --http-rewrite-url /v1/user/([^\/]+)/ping:/v2/user/$1/ping
-http-set-header value
Inject additional headers to http request:
gor --input-raw :8080 --output-http staging.com --http-set-header 'User-Agent: Gor'

-input-file-read-depth int
GoReplay tries to read and cache multiple records, in advance. In parallel it also perform sorting of requests, if they came out of order. Since it needs hold this buffer in memory, bigger values can cause worse performance (default 100)
