【转】wrk 压力测试的 lua脚本

转载：https://blog.csdn.net/qq_32373277/article/details/89453681

用 lua脚本同时GET,POST压测

category.lua 脚本如下：

urimap = {
    "/v3/goods/detail", 
    "/v3/goods/status",
    "/v3/goods/sku_detail",
    "/v3/coupons/lists",
    "/v3/pages/recommend",
    "/v3/carts",
}

methodmap = {
    "POST", 
    "POST",
    "POST",
    "GET",
    "GET",
    "GET",
}

params = {
      [[{"id":2}]], 
      [[{"spu_id":2,"type":1}]],
      [[{"id":2,"sku_id":7}]], -- 双中括号里面不转译
      "page=1&size=100",  
      "",
      "",
}

math.randomseed(os.time())

init = function()
    local r = {}
    local path = ""   -- 局部变量（不加local 是全局变量）
    local method = "get" -- 默认get

    -- header 头
    wrk.headers["Hash"]= "85280aa135bbd0108dd6aa424565a"
    wrk.headers["Token"]= ""
   
    for i, v in ipairs(urimap) do -- 键从1 开始 非 0
        path = v    -- 路径
        method = methodmap[i]  -- method

        if method == "POST" then
            wrk.headers["content-type"]= "application/json" --POST 参数json格式
            wrk.body = params[i]
        end

        if method == "GET" and  params[i] ~= "" then
            path = v .. "?" ..params[i]
        end

        io.write(method, "---", params[i], "----", path, "\n") -- 打印请求方式（1个线程会打印一次），参数，路径（不含域名）
        r[i] =  wrk.format(method, path)    
    end 

    req = table.concat(r)
end

request = function()
      return req
end
    
response = function(status, headers, body)  
    if status ~= 200 then
        print("status:", status)
        print("error:", body)
        wrk.thread:stop()
    else 
       -- print("body:", body)   
    end
end  

done = function(summary, latency, requests)

    local durations=summary.duration / 1000000    -- 执行时间，单位是秒
    local errors=summary.errors.status            -- http status不是200，300开头的
    local requests=summary.requests               -- 总的请求数
    local valid=requests-errors                   -- 有效请求数=总请求数-error请求数
  
    io.write("Durations:       "..string.format("%.2f",durations).."s".."\n")
    io.write("Requests:        "..summary.requests.."\n")
    io.write("Avg RT:          "..string.format("%.2f",latency.mean / 1000).."ms".."\n")
    io.write("Max RT:          "..(latency.max / 1000).."ms".."\n")
    io.write("Min RT:          "..(latency.min / 1000).."ms".."\n")
    io.write("Error requests:  "..errors.."\n")
    io.write("Valid requests:  "..valid.."\n")
    io.write("QPS:             "..string.format("%.2f",valid / durations).."\n")
    io.write("--------------------------\n")
  
end

脚本就这么完事了，开始压测吧！

wrk -t1 -c1000 -d30s -T10s -s category.lua --latency https://shop-api-crs.chi.com  

-t 开启多少线程
-c 连接数量 
-T 超时时间（timeout），支持时间单位 (s, m, h)
-s Lua脚本路径  
--latency 压测结束完，打印统计信息
