import Cookies from "js-cookie";

  data() {
      return {
        //登录表单
        loginForm: {
          username: "", //用户名
          password: "", //密码
          captcha: "", //验证码的值
          isRemember: false, //是否记住密码
        },
      }
    },

 created() {
      //一进页面就先获取cookies里面的参数
      this.getCookie()
    },
    methods: {
      // 获取cookie参数
      getCookie() {
        const username = Cookies.get("username");
        const password = Cookies.get("password");
        const isRemember = Cookies.get("isRemember");
        this.loginForm.username =
          username == undefined ? this.loginForm.username : username;
        this.loginForm.password =
          password == undefined ? this.loginForm.password : decrypt(password);
        this.loginForm.isRemember =
          isRemember == undefined ? false : Boolean(isRemember);
        Cookies.remove('data');
      },
    },
    onLogin() {
      //点击登录函数时,如果勾选记住密码
      if (this.loginForm.isRemember) {
        // 把账号密码等参数存到cookies,设置时间为30天
        Cookies.set("username", this.loginForm.username, {

JSON.parse(Cookies.get('userName'))

Cookies.remove('userName')
