安装mock axios

yarn add mock
yarn add axios

新建在src/mockdata/automenu.js    模拟后端的json数据格式

import Mock from 'mockjs'
Mock.mock('/menu','get',{
    status: 200,
    menuList: [
        {
            id : 1,
            iconCls: "fa fa-window",
            name: '系统管理',
            url: '/'
        },
        {
            id: 2,
            icon: 'icon-jurassic_user',
            name: '角色管理',
            url: '/'
        },
        {
            id: 3,
            icon: 'icon-shebei',
            name: '设备管理',
            url: '/',
        }
    ]
    }
)

在src/views/home.vue中 添加如下代码  前端axios测试

<template>
    <button @click="getData"> mock测试数据</button>
    <p>这是请求数据{{menuList.List}}}</p>
</template>

<script>
import axios from "axios";
import {reactive} from 'vue'

export default {
  name: "Home",
  setup() {
    //数据
    const menuList = reactive({List:[]});
    //测试方法
    const getData = async () => {
      await  axios({url:'/menu', method: 'get'}).then((res)=>{
        alert('请求成功');
        menuList.List = res.data.menuList
      })
    }
    return{
      menuList,
      getData
    }
  }
}
</script>
<style></style>
