Golang语言HTTP客户端的示例分析

这篇文章将为大家详细讲解有关Golang语言HTTP客户端的示例分析，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

HTTP客户端封装

package taskimport ( "bytes" "encoding/json" "fmt" "io/ioutil" "net/http" "net/url" "strings" "time")var Client http.Client = clients()// Res 模拟响应结构// @Description:type Res struct { Have string `json:"Have"`}// Get 获取GET请求// @Description:// @param uri// @param args// @return *http.Requestfunc Get(uri string, args map[string]interface{}) *http.Request { uri = uri +  "?" +ToValues(args) request, _ := http.NewRequest("get", uri, nil) return request}// PostForm POST接口form表单// @Description:// @param path// @param args// @return *http.Requestfunc PostForm(path string, args map[string]interface{}) *http.Request { request, _ := http.NewRequest("post", path, strings.NewReader(ToValues(args))) return request}// PostJson POST请求,JSON参数// @Description:// @param path// @param args// @return *http.Requestfunc PostJson(path string, args map[string]interface{}) *http.Request { marshal, _ := json.Marshal(args) request, _ := http.NewRequest("post", path, bytes.NewReader(marshal)) return request}// ToValues 将map解析成HTTP参数,用于GET和POST form表单// @Description:// @param args// @return stringfunc ToValues(args map[string]interface{}) string { if args != nil && len(args) > 0 {  params := url.Values{}  for k, v := range args {   params.Set(k, fmt.Sprintf("%v", v))  }  return params.Encode() } return ""}// Response 获取响应详情,默认[]byte格式// @Description:// @param request// @return []bytefunc Response(request *http.Request) []byte { res, err := Client.Do(request) if err != nil {  return nil } body, _ := ioutil.ReadAll(res.Body) // 读取响应 body, 返回为 []byte defer res.Body.Close() return body}// clients 初始化请求客户端// @Description:// @return http.Clientfunc clients() http.Client { return http.Client{  Timeout: time.Duration(5) * time.Second, //超时时间  Transport: &http.Transport{   MaxIdleConnsPerHost:   5,   //单个路由最大空闲连接数   MaxConnsPerHost:       100, //单个路由最大连接数   IdleConnTimeout:       90 * time.Second,   TLSHandshakeTimeout:   10 * time.Second,   ExpectContinueTimeout: 1 * time.Second,  }, }}// ParseRes 解析响应// @Description:// @receiver r// @param resfunc (r *Res) ParseRes(res []byte) { json.Unmarshal(res, r)}// ParseRes 解析响应,将[]byte转成传入对象// @Description:// @param res// @param r//func ParseRes(res []byte, r interface{}) { json.Unmarshal(res, r)}

测试脚本

package mainimport ( "fmt" "funtester/src/task" "io" "log" "net/http" "os" "time")const ( a = iota b c d e)func init() { os.Mkdir("./log/", 0777) os.Mkdir("./long/", 0777) file := "./log/" + string(time.Now().Format("20060102")) + ".log" openFile, _ := os.OpenFile(file, os.O_RDWR|os.O_CREATE|os.O_APPEND, 0666) writer := io.MultiWriter(os.Stdout, openFile) log.SetOutput(writer) log.SetFlags(log.LstdFlags | log.Lshortfile | log.Ldate)}func main() { url := "http://localhost:12345/test" args := map[string]interface{}{  "name": "FunTester",  "fun":  "fdsafj", } cookie := &http.Cookie{  Name:  "token",  Value: "fsjej09u0934jtej", } get := task.Get(url, args) get.Header.Add("user_agent", "FunTester") get.AddCookie(cookie) response := task.Response(get) fmt.Println(string(response)) form := task.PostForm(url, args) bytes := task.Response(form) fmt.Println(string(bytes)) json := task.PostJson(url, args) res := task.Response(json) fmt.Println(string(res))}

控制台输出

测试服务

依旧采用了moco_FunTester测试框架实现。

package com.mocofun.moco.mainimport com.funtester.utils.ArgsUtilimport com.mocofun.moco.MocoServerclass 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(urlStartsWith("/test")).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()    }}
