vue在登录时使用cookies记住密码

submitForm(formName) {
          var FormData = this.FormData;
          const _this = this;
          var obj = {
            loginId: FormData.username,
            password: FormData.password,
            verify: FormData.verify,
            sign: this.sign,
            authsign:FormData.authsign
          };
          // console.log(obj);
          this.$refs[formName].validate(valid => {
            if (valid) {
              this.$index.API_LOGIN(obj).then(res => {
                // console.log(res);
                if (res.errcode == 0) {           
                  
                  this.FormData.authsign = res.data.authsign;
                  localStorage.setItem("avatarImg", res.data.avatar);
                  localStorage.setItem("mobile", res.data.mobile);
                  localStorage.setItem("nickname", res.data.nickname);
                  localStorage.setItem("token", res.token);
                  this.$router.replace({ name: "FirstPaper" }); //登陆成功跳转到首页
    
                  //判断复选框是否被勾选 勾选则调用配置cookie方法
                  if (_this.checked == true) {
                    //传入账号名，密码，和保存天数3个参数
                    _this.setCookie(
                      _this.FormData.username,
                      _this.FormData.authsign,
                      7
                    );
                  } else {
                    _this.clearCookie(); //清空Cookie
                  }
                  localStorage.setItem("checked", this.checked);
                }
              });
            } else {
              console.log("error submit!!");
              return false;
            }
          });
        },
        //设置cookie
        setCookie(c_name, c_pwd, exdays) {
          var exdate = new Date(); //获取时间
          exdate.setTime(exdate.getTime() + 24 * 60 * 60 * 1000 * exdays); //保存的天数
          //字符串拼接cookie
          window.document.cookie =
            "userName" + "=" + c_name + ";path=/;expires=" + exdate.toGMTString();
          window.document.cookie =
            "authsign" + "=" + c_pwd + ";path=/;expires=" + exdate.toGMTString();
        },
        //读取cookie
        getCookie() {    
          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
            // console.log(arr);
            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] == "userName") {
                 this.checked=true;
                this.FormData.username = arr2[1]; //保存到保存数据的地方
              } else if (arr2[0] == "authsign") {
                this.FormData.authsign = arr2[1];
                this.FormData.password = arr2[1].substr(0,6);
              }
            }
          }
        },
        //清除cookie
        clearCookie() {
          this.setCookie("", "", -1); //修改2值都为空，天数为负1天就好了
        },

监听cookie,其中的“checked”为true则表示用户已勾选“记住密码”了。

mounted() {
        this.getCookie();
      },
      created() {
        //判断是否记住密码
        if (localStorage.getItem("checked") == 'true') {
          this.getCookie();
        }
      },

这里加密则是后台对我登录时输入数据进行加密然后把原先的“password”转换为后台加密返回的“authsign”即可。
