golang读取u盘序列号(通过读取序列号实现)

package main

import (
	"fmt"
	"log"
	"os"
	"strconv"
	"strings"

	registry "github.com/golang/sys/windows/registry"
)

func main() {
	//查询插入的u盘个数
	k,err := registry.OpenKey(registry.LOCAL_MACHINE,`SYSTEMCurrentControlSetServicesUSBSTOREnum`,registry.QUERY_VALUE)
	if err != nil {
		log.Fatal(err)
	}
	defer k.Close()

	n,_,err := k.GetIntegerValue("Count")
	if err != nil {
		log.Fatal(err)
	}
	if n < 1 {
		fmt.Println("没有检测到u盘！")
		os.Exit(-1)
	}

	//查询u盘序列号
	var sn,pvid,vid,pid string
	information,err := k.GetStringValue(strconv.Itoa(0))
	strn := strconv.FormatUint(n,10) //n是uint64类型，先转成string
	nInt,_ := strconv.Atoi(strn)     //再转成int类型
	if n > 1 {
		fmt.Printf("n检测到多个u盘，按插入顺序输出u盘信息nn")
	}
	for i := 0; i < nInt; i++ {
		information,err = k.GetStringValue(strconv.Itoa(i))
		if err != nil {
			log.Fatal(err)
		}
		sn = strings.Split(information,"")[2]
		pvid = strings.Split(information,"")[1]
		vid = strings.Split(pvid,"&")[0]
		vid = strings.Split(vid,"_")[1]
		pid = strings.Split(pvid,"&")[1]
		pid = strings.Split(pid,"_")[1]
		fmt.Println("当前u盘sn码:",sn)
		fmt.Println("当前u盘vid: ",vid)
		fmt.Println("当前u盘pid: ",pid)
		fmt.Println("")
	}
