好客租房121-租房小组分业务和数据处理
1根据当前地理位置展示不同小组信息
2根据后台接口找到找房数据
3前端只负责渲染
数据获取
1在state中获取数据
2根据文档获取数据
import React from 'react'
import axios from 'axios'
//留白
import { Carousel, Flex } from 'antd-mobile'

import Nav3 from '../../assets/images/nav-3.png'
import Nav4 from '../../assets/images/nav-4.png'
//导入样式

// 轮播图不会自动播放 数据返回过来的时候高度不够 数据加载前后数据的问题

总结
通过接口获取数据 获取到需要的数据格式
