这里介绍如何用go代码实现打开一个网页

也可以配合实现自建站点的打开

package main

import (
    "fmt"
    "net/http"
    "os/exec"
    "runtime"
    "strings"
    "time"
)

func main() {
    //go Server()
    r := Open("http://163.com")
    //r := Open("http://127.0.0.1:8080")
    fmt.Println(r)
    time.Sleep(1000 * time.Second)
}

var commands = map[string]map[string]string{
    "windows": map[string]string{"cmd": "cmd", "arg": "/c start"},
    "darwin":  map[string]string{"cmd": "open"},
    "linux":   map[string]string{"cmd": "xdg-open"},
}

// Open calls the OS default program for uri
func Open(url string) error {
    _, ok := commands[runtime.GOOS]
    if !ok {
        return fmt.Errorf("don't know how to open things on %s platform", runtime.GOOS)
    }
    args := strings.Split(commands[runtime.GOOS]["arg"], " ")
    args = append(args, url)
    res := exec.Command(commands[runtime.GOOS]["cmd"], args...)
    return res.Start()

}

func Server() {
    //http.Dir() 将字符串路径转换成文件系统
    h := http.FileServer(http.Dir("static"))                 //把本地static目录下资源建立一个文件服务器
    http.Handle("/static/", http.StripPrefix("/static/", h)) // 启动静态文件服务

    //启动
    http.HandleFunc("/", func(writer http.ResponseWriter, request *http.Request) {
        writer.Write([]byte("hello"))
    })
    //s:=http.Server{

    http.ListenAndServe(fmt.Sprintf(":%d", p), nil)
