golang搭建一个网站只是需要简单的几句就可以了

package main

import (
	"fmt"
	"log"
	"net/http"
	"strings"
)

func sayhelloName(w http.ResponseWriter,r *http.Request) {
	r.ParseForm() //解析参数，默认是不会解析的
	fmt.Println(r)
	fmt.Println(r.Form) //这些信息是输出到服务器端的打印信息
	fmt.Println("path",r.URL.Path)
	fmt.Println("scheme",r.URL.Scheme)
	fmt.Println(r.Form["url_long"])
	for k,v := range r.Form {
		fmt.Println("key:",k)
		fmt.Println("val:",strings.Join(v,""))
	}
	fmt.Println("love is ",r.Form["love"])
	fmt.Fprintf(w,"Hello astaxie!\n love the way you lie\n",strings.Join(r.Form["love"],"")) //这个写入到w的是输出到客户端的
}

func main() {

	http.HandleFunc("/hi",sayhelloName)     //设置访问的路由
	err := http.ListenAndServe(":9999",nil) //设置监听的端口
	if err != nil {
		log.Fatal("ListenAndServe: ",err)
	}

}

访问路径 http://localhost:9999/hi?love=peixuan

浏览器显示

Hello astaxie!
 love the way you lie
%!(EXTRA string=peixuan)

服务器输出

map[love:[peixuan]]

path /hi

scheme

[]

key: love

val: peixuan

love is [peixuan]

暂时先存个档，后期慢慢丰富。
