web.go

package main

import (
	"log"
	"net/http"
	"os"
	"strconv"
)

func main() {
	rootPath, _ := os.Getwd()
	http.Handle("/", http.StripPrefix("/", http.FileServer(http.Dir(rootPath))))
	Run(4321)
}

func Run(port int) {
	err := http.ListenAndServe(":"+strconv.Itoa(port), nil)
	if err != nil {
		log.Fatal("ListenAndServe: ", err)
	}
}

SimpleHTTPServer 性能太差了所以我用这个
