前端生成uid

index.js：
export function getUUID () {
  return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, c => {
    return (c === 'x' ? (Math.random() * 16 | 0) : ('r&0x3' | '0x8')).toString(16)
  })
}
//页面引入
import {getUUID} from "@/api/index";
 
查看获取uid：
mounted () {
        let uid = getUUID()
      //this.loginForm.uuid = getUUID();
      console.log(uid) // 39c15247-df27-4527-807d-abfa93765191
},
