-s, --script <S> Load Lua script file
-H, --header <H> Add header to request
--latency Print latency statistics
--timeout <T> Socket/request timeout
-v, --version Print version details
Numeric arguments may include a SI unit (1k, 1M, 1G)
Time arguments may include a time unit (2s, 2m, 2h)
-t：线程数
-c：客户端连接数
-d：压测事件
-T：设置超时时间
–latency：打印延时信息
-H：设置header信息
-s：lua脚本
二、Get 请求
mbp:~ pggsnap$ wrk -t 10 -c 200 -d 30s -T 3s --latency 'http://10.201.0.28:8080/dw-service/jres/test'

三、Lua 脚本
1、POST 请求
wrk -t 10 -c 100 -d 30s -s post.lua -T 1s --latency 'http://10.201.0.28:8888'
其中 post.lua 设置请求信息：
request = function()
local headers = {}
headers["Content-Type"] = "application/json"
local body = [[{
"abc": "123",
"xyz": {
"animal": "cat",
"color": "red"
}
}]]
return wrk.format('POST', nil, headers, body)
end
2、文件上传
curl -X POST \
'http://10.201.0.28:8888/api/v1/file/upload?biz=123 \
-H 'content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW' \
-F file=@/data/wrk/abc.txt
针对以上请求，编写对应的 lua 文件：
request = function()
local headers = {}
headers["Content-Type"] = "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW"
local biz = "123"
path = "/api/v1/file/upload?biz=" .. biz
body = '------WebKitFormBoundary7MA4YWxkTrZu0gW\r\n'
body = body .. [[Content-Disposition: form-data; name="file"; filename="abc.txt"]]
body = body .. '\r\n\r\n'
file = io.open("/data/wrk/abc.txt", "rb")
body = body .. file:read("*a")
body = body .. '\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--'
io.close(file)
return wrk.format('POST', path, headers, body)
end
