我是靠谱客的博主聪慧裙子，这篇文章主要介绍【golang】golang使用cmd去ping网址在window和linux的区别，现在分享给大家，希望可以做个参考。

设置ping的次数，在linux和window上，命令内容不一样
window

复制代码

2
ping -n 2 php-china.com

linux

复制代码

ping -c 2 php-china.com

复制代码

//设置类型别名
type Charset string

const (
	UTF8    = Charset("UTF-8")
	GB18030 = Charset("GB18030")
	UNKNOWN = Charset("UNKNOWN")
)

func main() {
	//获取当前系统
	sysType := runtime.GOOS
	switch sysType {
	case "windows":
		execCommandPingWeb("www.baidu.com", "-n", "2")
	case "linux":
		execCommandPingWeb("www.baidu.com", "-c", "2")
	default:
		log.Fatal("系统获取失败")
	}
	fmt.Println(runtime.GOOS)
}
func execCommandPingWeb(web string, arg ...string) {
	var outInfo, outErr bytes.Buffer
	cmd := exec.Command("ping", arg[0], arg[1], web)

cmd.Stdout = &outInfo
	cmd.Stderr = &outErr
	if err := cmd.Run(); err != nil {
		fmt.Println("错误", err)
		return
	}
	coding := GetStrCoding([]byte(outInfo.String()))
	res := ConvertByte2String([]byte(outInfo.String()), coding)
	fmt.Println(res)
}
func ConvertByte2String(byte []byte, charset Charset) Charset {
	var str Charset
	switch charset {
	case GB18030:
		var decodeBytes, _ = simplifiedchinese.GB18030.NewDecoder().Bytes(byte)
		str = Charset(decodeBytes)
	case UTF8:
		fallthrough
	default:
		str = Charset(byte)
	}

return str
}
