const express = require('express')
const app = express()
var appData = require('../address.json')
var apiRoutes = express.Router()
app.use('/api', apiRoutes) 
 
// 在devServer对象里添加如下代码：
 
before(app) {
      app.get('/api/address', (req, res) => {
        res.json({
          errno: 0,
          data: appData
        })
      })
    }

npm install --save axios vue-axios

import axios from 'axios'
Vue.prototype.$http = axios

 this.$http.get('/api/address').then(response => {
      console.log(response)
 }, response => {
      console.log('数据加载失败')
 })
