我先说我的操作步骤：（前提是要有node.js没有的npm吧）
第一步：新建一个文件夹，命名随便；然后在文件里打开命令行输入以下命令
npm init -y
npm i express
文件夹就会多一个node_moudules文件和两个json文件
接下来在自己的编辑器上新建一个app.js文件,内容如下
const express = require('express')
const bodyParser = require('body-parser')///npm i body-parser自己去下载，用于post请求的
const app = express()
app.use(bodyParser.urlencoded({
extended: false
}))
//parse application/json
app.use(bodyParser.json())
const broadcast = [{
carouselImg: '../../assets/images/carousel1.jpg'
},
{
carouselImg: '../../assets/images/carousel2.jpg'
},
{
carouselImg: '../../assets/images/carousel3.jpg'
},
{
carouselImg: '../../assets/images/carousel4.jpg'
}
]

const longitude = [
{
code: 0,
latitude: '39.91667', //纬度

app
.get('/broadcast', (req, res) => {
res.json(broadcast)
})
.get('/todos', (req, res) => {
res.json(todos)
})
.get('/longitude', (req, res) => {
//console.log(req)
let id = req.query.id
for(let i = 0; i < longitude.length; i++) {
if(longitude[i].address.geohash == id) {
res.json({
address: longitude[i]
})
return
}
}
})
.post('/todos', (req, res) => {
console.log(req.body)
const todo = {
name: req.body.name,
years: req.body.years,
id: todos[todos.length - 1].id + 1
}
todos.push(todo)
res.json(todo)
})
app.listen(3000, () => console.log('api server running 3000.'))然后呢再在这个根文件里输入 nodemon app.js
这样自己模拟的服务器接口数据就跑起了。
举例请求一个get数据todos
axios.get('http://192.168.0.121:3000/todos').then(res => {
console.log(res)
this.lists = res.data
console.log(this.lists)
//this.lists = JSON.parse(localStorage.getItem('zhi')) || this.lists;
let get=JSON.parse(localStorage.getItem("zhi"));
console.log(get)
if(get!=null){
this.lists=get
}else{
this.lists= this.lists
}
localStorage.setItem('zhi', JSON.stringify(this.lists));
console.log(this.lists)
}, err => {
console.log(err)
})
