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

javascript 复制代码
//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;
