go启动一个简单的httpserver

package main

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

func main() {
   http.HandleFunc("/", sayhelloName) //设置访问的路由

   err := http.ListenAndServe(":8080", nil) //设置监听的端口
   if err != nil {
      log.Fatal("ListenAndServe: ", err)
   }
}

func sayhelloName(w http.ResponseWriter, r *http.Request) {
   fmt.Fprintf(w, "Hello Wrold!") //这个写入到w的是输出到客户端的
}
