go语言实现简单的http客户端与服务器

服务器代码

package main

import (
	"fmt"
	"net/http"
)

func main(){
	//注册粗婚礼函数，用户连接，自动调用指定的处理函数
	http.HandleFunc("/",HandConn)

	//监听绑定
	http.ListenAndServe(":8080",nil)
}
//w，给客户端回复数据
//req，读取客户端发送的数据
func HandConn(w http.ResponseWriter,req *http.Request){
	w.Write([]byte("hello go"))
	fmt.Println("req.Method = ",req.Method)
	fmt.Println("req.Header = ",req.Header)
	fmt.Println("req.URL = ",req.URL)
	fmt.Println("req.Body = ",req.Body)
}

客户端代码

package main

import (
	"fmt"
	"net/http"
)

func main(){
	resp,err := http.Get("http://www.ytu.edu.cn")
	if err != nil{
		fmt.Println("http.Get err:",err)
		return
	}

	defer resp.Body.Close()

	fmt.Println("Status:",resp.Status)
	fmt.Println("StatusCode:",resp.StatusCode)
	fmt.Println("Header:",resp.Header)
	fmt.Println("Body:",resp.Body)
	//读取body中的数据，body为IO
	buf := make([]byte,1024*4)
	var tmp string
	for{
		n,err1 := resp.Body.Read(buf)
		if n == 0 {
			fmt.Println("resp.Body.Read err:",err1)
			fmt.Println("ok")
			break
		}
		tmp += string(buf[:n])
	}
	fmt.Println("tmp = ",tmp)
}
