如何用go程序打开一个网站
2022.02

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{
	//	Addr:              "127.0.0.1:8080",
	//	Handler:           nil,

	//}
	p := 8080
	http.ListenAndServe(fmt.Sprintf(":%d", p), nil)
}
