对于web开发者来收, 需要快速搭建一个web服务, 之前都在使用 nodejs实现的 http-server
今天发现golang可以30行代码搞定类似http-server的功能, golang着实强大.

简单说明, 和代码

flag包处理命令行的参数, fmt包不多说, net/http负责http的服务 log负责打印点日志

package main

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

var (
    port int
    host string
    path string
)

func init() {
    flag.IntVar(&port, "port", 8000, "server port listen")
    flag.StringVar(&host, "host", "0.0.0.0", "host ip address")
    flag.StringVar(&path, "path", "./", "server document root")
    flag.Parse()
}

func main() {
    log.Printf("server listen at [%v]:[%v] and document root is [%v]\n", host, port, path)
    log.Println(path)
    fs := http.FileServer(http.Dir(path))
    http.Handle("/", fs)
    http.ListenAndServe(fmt.Sprintf("%v:%v", host, port), nil)
}

$ gohttpserver.exe -h
    Usage of gohttpserver.exe:
      -host string
            host ip address (default "0.0.0.0")
      -path string
            server document root (default "./")
      -port int
            server port listen (default 8000)

启动 gohttpserver.exe --host=127.0.0.1 --port=9999 --path=d:/workspaces
