go get github.com/adeven/go-wrk
使用方法同wrk类似，基本格式如下：
go-wrk [flags] url
常用的参数：
-H="User-Agent: go-wrk 0.1 bechmark\nContent-Type: text/html;": 由'\n'分隔的请求头
-c=100: 使用的最大连接数
-k=true: 是否禁用keep-alives
-i=false: if TLS security checks are disabled
-m="GET": HTTP请求方法
-n=1000: 请求总数
-t=1: 使用的线程数
-b="" HTTP请求体
-s="" 如果指定，它将计算响应中包含搜索到的字符串s的频率
执行测试：
go-wrk -t=8 -c=100 -n=10000 "http://127.0.0.1:8080/api/v1/posts?size=10"
输出结果：
