在utils文件夹中创建cookie.js并复制以下代码

/* eslint-disable */function addCookie(cookieKey, cookieValue, overSeconds) {  document.cookie = cookieKey + "=" +cookieValue +";max-age="+overSeconds;}function deleteCookie(cookieKey){  addCookie(cookieKey,"",-1);}export default function getCookie(cookieKey){  var arr = document.cookie.split("; ");  for (var i = 0;i < arr.length;i++) {    var arr2 = arr[i].split("=");    if (arr2[0].trim() == cookieKey) {      return arr2[1];    }  }}function isCookieKey(cookieKey){  var arr = document.cookie.split(";");  for (var i = 0;i < arr.length;i++) {    var arr2 = arr[i].split("=");    if (arr2[0].trim() == cookieKey) {      return true;    }  }  return false;}export {  addCookie, deleteCookie, isCookieKey}复制代码
