介绍
http_bench是HTTP(HTTP/1, HTTP/2, HTTP/3, Websocket)压测工具，并支持单机和分布式，为了简洁，直接用1000行左右实现。有兴趣读源码朋友，可以点击【阅读原文】或者访问【开源地址】（当前项目已经接入Github Actions，适配了golang1.18，golang1.19，golang1.20）。

命令行解析
代码语言：javascript复制-n 请求HTTP的次数
-c 并发的客户端数量，但是不能大于HTTP的请求次数
-q 频率限制，每秒的请求数
-d 压测持续时间，默认10秒，例如：2s, 2m, 2h（s:秒，m:分钟，h:小时）
-t 设置请求的超时时间，默认3s
-o 输出结果格式，可以为CSV，也可以直接打印
-m HTTP方法，包括GET, POST, PUT, DELETE, HEAD, OPTIONS.
-H 请求发起的HTTP的头部信息，例如：-H "Accept: text/html" -H "Content-Type: application/xml"
-body HTTP发起POST请求的body数据
-a HTTP的鉴权请求, 例如：http://username:password@xxx/
-http 支持http1, http2, http3, ws和wss, 默认http1
-x HTTP的代理IP和端口
-disable-compression 不启用压缩
-disable-keepalive 不开启keepalive
-cpus 使用cpu的内核数
-url 压测单个URL
-verbose 打印详细日志，默认等级：3(0:TRACE, 1:DEBUG, 2:INFO, 3:ERROR)
-url-file 读取文件中的URL，格式为一行一个URL，发起请求每次随机选择发送的URL
-body-file 从文件中读取请求的body数据
-listen 分布式压测任务机器监听IP:PORT，例如： "127.0.0.1:12710".
-dashboard 监听端口，浏览器发起压测和查看QPS曲线.
-W 分布式压测执行任务的机器列表，例如： -W "127.0.0.1:12710" -W "127.0.0.1:12711".
-example 打印样例信息.
执行压测样例(使用"-verbose 1"打印详细日志):
代码语言：javascript复制./http_bench -n 1000 -c 10 -m GET -url "http://127.0.0.1/test1"
./http_bench -n 1000 -c 10 -m GET "http://127.0.0.1/test1"
执行压测按照文件随机压测(使用"-verbose 1"打印详细日志):
代码语言：javascript复制./http_bench -n 1000 -c 10 -m GET "http://127.0.0.1/test1" -url-file urls.txt
./http_bench -d10s -c 10 -m POST "http://127.0.0.1/test1" -body "{}" -url-file urls.txt
执行压测，使用http/2:
代码语言：javascript复制./http_bench -d 10s -c 10 -http http2 -m POST "http://127.0.0.1/test1" -body "{}"
执行压测，使用http/3:
代码语言：javascript复制./http_bench -d 10s -c 10 -http http3 -m POST "http://127.0.0.1/test1" -body "{}"
分布式压测样例(使用"-verbose 1"打印详细日志):
代码语言：javascript复制(1) 第一步:
./http_bench -listen "127.0.0.1:12710" -verbose 1
./http_bench -listen "127.0.0.1:12711" -verbose 1
(2) 第二步:
./http_bench -c 1 -d 10s "http://127.0.0.1:18090/test1" -body "{}" -W "127.0.0.1:12710" -W "127.0.0.1:12711" -verbose 1
