Golang fasthttp实践

2022-03-09 作者: FunTester

原计划学完之后，就可以继续了，没想到才疏学浅，在搜资料的时候发现除了Golang SDK自带的net/http，还有一个更牛的HttpClient实现github.com/valyala/fasthttp，据说性能是net/http的10倍，我想可能是有点夸张了，后期我会进行测试，以正视听。

在用到了对象池，为了在高性能测试中减少内存的使用，fasthttp使用了两个对象池（我只看了这俩）：和，当然fasthttp也提供了正常的对象创建API，后面我在案例中也会写到。

基础API演示

首先分享一下基础的用法封装：

PS：这个属于练习版本，所以没写多少注释。

package ft

import (
  "encoding/json"
  "fmt"
  "funtester/task"
  "github.com/valyala/fasthttp"
)


func FastGet(url string, args map[string]interface{}) ([]byte, error) {
  uri := url + "?" + task.ToValues(args)
  _, resp, err := fasthttp.Get(nil, uri)
  if err != nil {
    fmt.Println("请求失败:", err.Error())
    return nil, err
  }
  return resp, err
}

func FastPostForm(url string, args map[string]interface{}) ([]byte, error) {

  // 填充表单，类似于net/url
  params := &fasthttp.Args{}
  for s, i2 := range args {
    sprintf := fmt.Sprintf("%v", i2)
    params.Add(s, sprintf)
  }
  _, resp, err := fasthttp.Post(nil, url, params)
  if err != nil {
    fmt.Println("请求失败:", err.Error())
    return nil, err
  }
  return resp, nil
}

func FastPostJson(url string, args map[string]interface{}) ([]byte, error) {

  req := &fasthttp.Request{}
  req.SetRequestURI(url)

  marshal, _ := json.Marshal(args)
  req.SetBody(marshal)

  // 默认是application/x-www-form-urlencoded,其实无所谓
  req.Header.SetContentType("application/json")
  req.Header.SetMethod("POST")

  resp := &fasthttp.Response{}
  if err := fasthttp.Do(req, resp); err != nil {
    fmt.Println("请求失败:", err.Error())
    return nil, err
  }
  return resp.Body(), nil
}

其中两点主要注意：

  • FastGet、FastPostForm使用的fasthttp提供的默认获取请求的方式，FastPostJson使用了自定义请求和获取响应的方式

  • 关于请求头中的req.Header.SetContentType方法，其实无所谓，服务端都可以解析

高性能API演示

下面分享使用更高的性能（基于对象池）的API创建请求和获取响应的方式：

package task

import (
  "crypto/tls"
  "encoding/json"
  "fmt"
  "github.com/valyala/fasthttp"
  "log"
  "time"
)

var FastClient fasthttp.Client = fastClient()

// FastGet 获取GET请求对象,没有进行资源回收
// @Description:
// @param url
// @param args
// @return *fasthttp.Request
func FastGet(url string, args map[string]interface{}) *fasthttp.Request {
  req := fasthttp.AcquireRequest()
  req.Header.SetMethod("GET")
  values := ToValues(args)
  req.SetRequestURI(url + "?" + values)
  return req
}

// FastPostJson POST请求JSON参数,没有进行资源回收
// @Description:
// @param url
// @param args
// @return *fasthttp.Request
func FastPostJson(url string, args map[string]interface{}) *fasthttp.Request {
  req := fasthttp.AcquireRequest()
  // 默认是application/x-www-form-urlencoded
  req.Header.SetContentType("application/json")
  req.Header.SetMethod("POST")
  req.SetRequestURI(url)
  marshal, _ := json.Marshal(args)
  req.SetBody(marshal)
  return req
}

// FastPostForm POST请求表单传参,没有进行资源回收
// @Description:
// @param url
// @param args
// @return *fasthttp.Request
func FastPostForm(url string, args map[string]interface{}) *fasthttp.Request {
  req := fasthttp.AcquireRequest()
  // 默认是application/x-www-form-urlencoded
  //req.Header.SetContentType("application/json")
  req.Header.SetMethod("POST")
  req.SetRequestURI(url)
  marshal, _ := json.Marshal(args)
  req.BodyWriter().Write([]byte(ToValues(args)))
  req.BodyWriter().Write(marshal)
  return req
}

// FastResponse 获取响应,保证资源回收
// @Description:
// @param request
// @return []byte
// @return error
func FastResponse(request *fasthttp.Request) ([]byte, error) {
  response := fasthttp.AcquireResponse()
  defer fasthttp.ReleaseResponse(response)
  defer fasthttp.ReleaseRequest(request)
  if err := FastClient.Do(request, response); err != nil {
    log.Println("响应出错了")
    return nil, err
  }
  return response.Body(), nil
}

// DoGet 发送GET请求,获取响应
// @Description:
// @param url
// @param args
// @return []byte
// @return error
func DoGet(url string, args map[string]interface{}) ([]byte, error) {
  req := fasthttp.AcquireRequest()
  defer fasthttp.ReleaseRequest(req) // 用完需要释放资源
  req.Header.SetMethod("GET")
  values := ToValues(args)
  req.SetRequestURI(url + "?" + values)
  resp := fasthttp.AcquireResponse()
  defer fasthttp.ReleaseResponse(resp) // 用完需要释放资源
  if err := FastClient.Do(req, resp); err != nil {
    fmt.Println("请求失败:", err.Error())
    return nil, err
  }
  return resp.Body(), nil
}

// fastClient 获取fast客户端
// @Description:
// @return fasthttp.Client
func fastClient() fasthttp.Client {
  return fasthttp.Client{
    Name:                     "FunTester",
    NoDefaultUserAgentHeader: true,
    TLSConfig:                &tls.Config{InsecureSkipVerify: true},
    MaxConnsPerHost:          2000,
    MaxIdleConnDuration:      5 * time.Second,
    MaxConnDuration:          5 * time.Second,
    ReadTimeout:              5 * time.Second,
    WriteTimeout:             5 * time.Second,
    MaxConnWaitTimeout:       5 * time.Second,
  }
}

测试服务

用的还是moco_FunTester测试框架，脚本如下：

package com.mocofun.moco.main

import com.funtester.utils.ArgsUtil
import com.mocofun.moco.MocoServer
import org.apache.tools.ant.taskdefs.condition.And

class Share extends MocoServer {

    static void main(String[] args) {
        def util = new ArgsUtil(args)
        //                def server = getServerNoLog(util.getIntOrdefault(0,12345))
        def server = getServer(util.getIntOrdefault(0, 12345))
        server.get(both(urlStartsWith("/test"),existArgs("code"))).response("get请求")
        server.post(both(urlStartsWith("/test"), existForm("fun"))).response("post请求form表单")
        server.post(both(urlStartsWith("/test"), existParams("fun"))).response("post请求json表单")
        server.get(urlStartsWith("/qps")).response(qps(textRes("恭喜到达QPS!"), 1))
//        server.response(delay(jsonRes(getJson("Have=Fun ~ Tester ！")), 1000))
        server.response("Have Fun ~ Tester ！")
        def run = run(server)
        waitForKey("fan")
        run.stop()
    }
}

Golang单元测试

第一次写Golang单测，有点不适应，搞了很久才通。

package test

import (
  "funtester/ft"
  "funtester/task"
  "log"
  "testing"
)

const url = "http://localhost:12345/test"

func args() map[string]interface{} {
  return map[string]interface{}{
    "code": 32,
    "fun":  32,
    "msg":  "324",
  }
}

func TestGet(t *testing.T) {
  get := task.FastGet(url, args())
  res, err := task.FastResponse(get)
  if err != nil {
    t.Fail()
  }
  v := string(res)
  log.Println(v)
  if v != "get请求" {
    t.Fail()
  }
}

func TestPostJson(t *testing.T) {
  post := task.FastPostJson(url, args())
  res, err := task.FastResponse(post)
  if err != nil {
    t.Fail()
  }
  v := string(res)
  log.Println(v)
  if v != "post请求json表单" {
    t.Fail()
  }
}

func TestPostForm(t *testing.T) {
  post := task.FastPostForm(url, args())
  res, err := task.FastResponse(post)
  if err != nil {
    t.Fail()
  }
  v := string(res)
  log.Println(v)
  if v != "post请求form表单" {
    t.Fail()
  }
}

func TestGetNor(t *testing.T) {
  res, err := ft.FastGet(url, args())
  if err != nil {
    t.Fail()
  }
  v := string(res)
  log.Println(v)
  if v != "get请求" {
    t.Fail()
  }
}

func TestPostJsonNor(t *testing.T) {
  res, err := ft.FastPostJson(url, args())
  if err != nil {
    t.Fail()
  }
  v := string(res)
  log.Println(v)
  if v != "post请求json表单" {
    t.Fail()
  }
}

func TestPostFormNor(t *testing.T) {
  res, err := ft.FastPostForm(url, args())
  if err != nil {
    t.Fail()
  }
  v := string(res)
  log.Println(v)
  if v != "post请求form表单" {
    t.Fail()
  }
}
