登录权限

使用token对用户鉴，使用cookie对当前信息保存（类似localstorage）

安装cookie

npm i js-cookie@3.0.1

Login.vue

//登录submitForm(formName) {this.$refs[formName].validate((valid) => {if (valid) {//token信息const token=Mock.Random.guid()  //生成随机数//token信息存入cookie用于不同页面间的通信Cookie.set('token',token)//跳转到首页this.$router.push('/home')} else {console.log('error submit!!');return false;}});},
