golang实现http文件服务器,golang http服务器处理静态文件

新版本更精简:

package main

import (

"flag"

"log"

"net/http"

"os"

"io"

"path"

"strconv"

)

var dir string

var port int

var staticHandler http.Handler

// 初始化参数

func init() {

dir = path.Dir(os.Args[0])

flag.IntVar(&port, "port", 80, "服务器端口")

flag.Parse()

staticHandler = http.FileServer(http.Dir(dir))

}

func main() {

http.HandleFunc("/", StaticServer)

err := http.ListenAndServe(":"+strconv.Itoa(port), nil)

if err != nil {

log.Fatal("ListenAndServe: ", err)

}

}

// 静态文件处理

func StaticServer(w http.ResponseWriter, req *http.Request) {

if req.URL.Path !
