VUE:vue通过cookie获取用户登录信息

思路

  • 进入页面
  • 若未登录,跳转至登陆页面
  • 若已登录,从cookie中获取用户信息,并执行后续操作

1. 登录页面,存入cookie(setCookie)

import {setCookie,getCookie}from 'src/js/cookieUtil'
  methods: {
    async cheack_n_p () {
      if( this.checkCode === this.pwd) {
        this.loginData = await getUserInfo(this.uname, this.pwd, this.adminPhone);
        if (this.loginData.res !== 0) {
          setCookie('userName',this.uname);
          setCookie('userPwd',this.pwd,);
          setCookie('phone',this.uname);
          setCookie('userId',this.loginData.obj.id);
          setCookie('userType',this.loginData.obj.userType);
          setCookie('adminPhone',this.adminPhone);
//        this.$router.go(-1);
          this.$router.replace('/');
        } else {
          alert("验证码错误!")
        }
      }
    },
  },

2. 页面判断

import {setCookie,getCookie}from 'src/js/cookieUtil'
  mounted () {
    if (this.isLogin==undefined||this.isLogin=="") {
      this.$router.replace('/login');
    } else {
      // 执行后续操作
      this.phone = getCookie("phone");
      }
  },
  computed: {
    isLogin () {
      // return this.$store.getters.getLogin;
      this.userId = getCookie("userId");
     // console.log(this.userId);
      return this.userId;
    }
  },

3. cookieUtil(setCookie,getCookie)

/**
 * Created by Schon on 2018/9/13 0013.
 */
//设置cookie
export function setCookie(key,value) {
  var exdate = new Date(); //获取时间
  exdate.setTime(exdate.getTime() + 24 * 60 * 60 * 1000 * 36500); //保存的天数,我这里写的是100年
  //字符串拼接cookie
  window.document.cookie = key + "=" + value + ";path=/;expires=" + exdate.toGMTString();
};
//读取cookie
export function getCookie(param) {
  var c_param = '';
  if (document.cookie.length > 0) {
    var arr = document.cookie.split('; '); //这里显示的格式需要切割一下自己可输出看下
    for (var i = 0; i < arr.length; i++) {
      var arr2 = arr[i].split('='); //再次切割
      //判断查找相对应的值
      if (arr2[0] == param) {
        c_param = arr2[1];
        //保存到保存数据的地方
      }
    }
    return c_param;
  }
};
function padLeftZero (str) {
  return ('00' + str).substr(str.length);
};
