1.下载express
...
2.使用vue-cli下载好项目文件
...
3.找到文件 build - webpack.dev.conf.js
'use strict'

//1.读取数据
var appData=require('../static/json/table.json');
var businessNum=appData.businessNum;

var customerData=appData.businessNum; //2.使用expresss配置路由，指定接口请求
var apiRoutes=express.Router(); //定义一个路由 const devWebpackConfig = merge(baseWebpackConfig, {

4.在页面中发送axios请求（先在main.js中引入axios）
...
import axios from 'axios'
...
/* 全局引入axios */
Vue.prototype.$http = axios
5.在页面中请求数据
created () {
this.$http.get('/api/businessNum').then(response => {
console.log(response)
}).catch(response => {
console.log(response)
})
}
6.页面加载返回数据信息
