我自己又在 GitHub 上搜罗了几个:

package main

import (

    guuid ""
    suuid ""

func UseGoogle() string {
    id := guuid.New()
    return id.String()

func UseSatori() string {
    id := suuid.NewV4()
    return id.String()

func UseUuidgen() string {
    id, _ := exec.Command("uuidgen").Output()
    return string(id)

func main() {
    fmt.Println("Google UUID:", UseGoogle())
    fmt.Println("Satori UUID:", UseSatori())
    fmt.Println("Uuidgen UUID:", UseUuidgen())
