分析一个项目讲究的是如何进行对项目的解析分解，进一步了解项目的整体结构，熟悉项目的结构，能够知道每个组件所处在哪个位置，发挥什么作用。
接下来分析接口方面：
首先对于基础接口定义为本地接口：$http.baseUrl='http://localhost:3000'
home接口：
javascript
const {
data: res
} = await uni.$http.get('/home')
if (res.meta.status !== 200) {
return uni.$showMsg();
}
// 对数据进行处理
res.message.forEach(floor => {
floor.product_list.forEach(prod => {
prod.url = '/subpkg/goods_list/goods_list?' + prod.navigator_url.split('?')[1]
})
})
this.floorList = res.message接口为：http://localhost:3000/home/swiper
使用node创建本地服务器端：
index.js如下：
javascript
// 1.导包
const express = require("express")
// 2.创建服务器
const app = express()
//3.编写接口get方法
app.get("/home",(req,res)=>{
res.send({
"message": [
{
"floor_title": {
"name": "测试",
"image_src": "https://tse2-mm.cn.bing.net/th/id/OIP-C.7BGLFWgbSBaoawzV_Gp7VQHaNK?w=208&h=326&c=7&r=0&o=5&dpr=1.3&pid=1.7"
},
"product_list": [
{
"name": "爆款清仓",
"image_src": "https://tse1-mm.cn.bing.net/th/id/OIP-C.IYo1y_dmp-LOIyvc7rpPrgHaHa?w=193&h=193&c=7&r=0&o=5&dpr=1.3&pid=1.7",
"image_width": "233",
"open_type": "navigate",
"navigator_url": "/pages/goods_list?query=爆款"
},
]
},
{

},

}
]
},
],
"meta": {
"msg": "获取成功",
"status": 200
}
})
})
// 4.监听端口
app.listen(3000,()=>{
console.log("启动成功");
})接口请求成功后，将数据渲染到页面：
categories接口：
index.js如下：
javascript
app.get("/categories",(req,res)=>{
res.send({
"message": [
{
"cat_id": 1,
"cat_name": "大家电",
"cat_pid": 0,
"cat_level": 0,
