npm install uuid
npm install uuid --save
cnpm i -S vue-uuid

import { v4 as uuidv4 } from 'uuid';
uuidv4(); // ⇨ '9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d'

const { v4: uuidv4 } = require('uuid');
uuidv4(); // ⇨ '1b9d6bcd-bbfd-4b2d-9b5d-ab8dfbbd4bed'

const uuid = require('uuid') //1、引包
console.log(uuid.v1()) //2、调用 98fc11a0-dde0-11e9-ade5-25202b3a2fba

import UUID from "vue-uuid";
Vue.use(UUID);

console.log("this.$uuid.v1():", this.$uuid.v1());
// this.$uuid.v1()：b1ef4cf0-ae0d-11eb-bed8-596efe8bfb0b

import { uuid } from 'vue-uuid';

 uuid.v1()

import { v4 as uuidv4 } from ‘uuid'

const uuid = uuidv4()　
this.sessionId = uuid.v4()
console.log(this.sessionId)

# 下载
cnpm i -S uuid

const uuid = require('uuid')
console.log("uuid.v4()", uuid.v4())

  "uuid": "^8.3.1",

import { v4 as uuidv4 } from 'uuid';

// 全局方法挂载
Vue.prototype.uuidv4 = uuidv4

click(){
    var temp_event = this.uuidv4();
    console.log('temp_event',temp_event);
    eventBus.$on(temp_event,res=>{
       this.getList();
       eventBus.$off(temp_event);
    });
}

uuid.v4() //直接加在页面的任意位置

let uuid = sessionStorage.getItem('uuid');
if (!uuid) {
  sessionStorage.setItem('uuid',uuidv4());
}

let uuid = localStorage.getItem('uuid');
if (!uuid) {
  localStorage.setItem('uuid',uuidv4());
}

if (getToken()){//判断是否有 token
  sessionStorage.removeItem('uuid'); //如果有，清除 sessionStorage 中的 uuid
} else {//未登录状态生成 uuid
  let uuid = sessionStorage.getItem('uuid');
  if (!uuid) {
    sessionStorage.setItem('uuid',uuidv4());
  }
}
