vue中使用cookie實現(xiàn)記住用戶上一次的選擇

//設(shè)置cookie
    setCookie(projectId,exdays) {
      var exdate=new Date();//獲取時間
      exdate.setTime(exdate.getTime() + 24*60*60*1000*exdays);//保存的天數(shù)
      //字符串拼接cookie
      window.document.cookie="projectId"+ "=" +projectId+";expires="+exdate.toGMTString();
    },
    //讀取cookie
    getCookie:function () {
    console.log(document.cookie);
    let me=this;
    if (document.cookie.length>0) {
      var arr=document.cookie.split('; ');//這里顯示的格式需要切割一下自己可輸出看下
      for(var i=0;i<arr.length;i++){
      var arr2=arr[i].split('=');//再次切割
      //判斷查找相對應(yīng)的值
      if(arr2[0]=='projectId'){
        me.workhourData.projectId=arr2[1];//保存到保存數(shù)據(jù)的地方
      }
      }
    }
    },
    //清除cookie
    clearCookie:function () {
    this.setCookie("","",-1);//修改2值都為空，天數(shù)為負1天就好了
    },

//上方引入的index.js
import axios from 'axios'
import {baseUrl} from "./config";
import $ from 'jquery'
import './base'

export const getAccount=()=>{
  return axios.post(`${baseUrl}/index/index/index`).then(res=>{
    return res.data;

 if(typeof data=='object'){
 return qs.stringify(data);
 }else{
 return data;
 }
  
}];

axios.defaults.transformResponse=[function(data){ //攔截response請求，做統(tǒng)一跳轉(zhuǎn)
 data=JSON.parse(data);
 if(data.status=='-99'){
 router.push({path:'/login'});
 }
 return data;
}];

//跨域訪問的時候才會存在此字段
