vue中json-server及mockjs后端接口模拟

一、接口配置

1.安装json-server;

pnpm i json-server@0.17.3 -D

2.安装mockjs;

pnpm i mockjs -D

3.把json数据放在合适的位置，在根目录下创建mock.js文件，引入json数据;

4.在package.json中添加

"mock": "json-server -w mock.js -p 3000"

删除

 "type": "module",

 5.启动服务;

pnpm mock

 二、axios请求数据

 1.安装axios;

pnpm i axios

2.在src文件夹下创建api文件夹，创建接口文件index.js，封装接口;

3.使用数据

<script setup>
import { getWuhanBuildings,getWuhanRoads } from '@/api';
import { inject,onMounted, onBeforeUnmount} from 'vue'
const {map,scene} = inject('mapScene')
onMounted(async() => {
    map.flyTo({
        center: [114.299987, 30.58518],
        zoom: 15,
        pitch:45,
    }) 
    //加载城市建筑和道路数据
    const { data: buildingsData } = await getWuhanBuildings();
    const { data: roadsData } = await getWuhanRoads();
    console.log(buildingsData,roadsData)
})

onBeforeUnmount(() => {})
</script>
