server端：

package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	//注册路由  func是回调函数，用于路由的响应，
	http.HandleFunc("/user", func(writer http.ResponseWriter, request *http.Request) {
		//request：包含客户端发来的数据
		fmt.Println("客户请求：",request)
		//write：通过write将数据返回给客户端
		_, _ = io.WriteString(writer, "这是/user返回的数据")
	})
	//请求指定路由，返回指定结果
	http.HandleFunc("/name", func(writer http.ResponseWriter, request *http.Request) {
		_, _ = io.WriteString(writer, "这是/name返回的数据")
	})
	//请求指定路由，返回指定结果
	http.HandleFunc("/id", func(writer http.ResponseWriter, request *http.Request) {
		_, _ = io.WriteString(writer, "这是/id返回的数据")
	})
	fmt.Println("http start")

	if err := http.ListenAndServe("localhost:8088", nil);err != nil {
		fmt.Println("启动服务失败",err)
		return
	}
}

client端：

package main

import (
	"fmt"
	"io/ioutil"
	"net/http"
)

func main() {
	//http包
	client := http.Client{}
	//func (c *Client) Get(url string) (resp *Response, err error)
	//get到需要测试的url
	resp, err := client.Get("https://www.baidu.com")
	if err != nil {
		fmt.Println("请求失败",err)
		return
	}

	//get到header的指定key
	ct := resp.Header.Get("Content-Type")
	date := resp.Header.Get("Date")
	sr := resp.Header.Get("Server")
	//输出打印结果
	fmt.Println(ct,date,sr)

	//获取请求的url，状态码，状态
	url := resp.Request.URL
	code := resp.StatusCode
	status := resp.Status
	//输出打印结果
	fmt.Println(url,code,status)

	//拿到Body体内的所有内容
	body := resp.Body
	//输出打印body
	fmt.Println(body)
	//接收body转换为string类型
	readAll, err := ioutil.ReadAll(body)
	if err != nil {
		fmt.Println("请求body失败",err)
		return
	}
	//输出结果
	fmt.Println(string(readAll))
}

先启动server在启动client
