How to obtain static json data using http request in vue2.5.2

This article mainly introduces the example code of vue2.5.2 using http request to obtain static json data. Friends who need it can refer to it

1. Configure build/webpack.dev.conf.js

// 获取静态json数据
const express = require('express')
const app = express()
const apiServer = express()
const bodyParser = require('body-parser')
apiServer.use(bodyParser.urlencoded({ extended: true }))
apiServer.use(bodyParser.json())
const apiRouter = express.Router()
const fs = require('fs')
apiRouter.route('/:apiName')
 .all(function (req, res) {
  fs.readFile('./db.json', 'utf8', function (err, data) {
   if (err) throw err
   var data = JSON.parse(data)
   if (data[req.params.apiName]) {
    res.json(data[req.params.apiName])
   }
   else {
    res.send('no such api name')
   }
  })
 })
apiServer.use('/api', apiRouter);
apiServer.listen(8081, function (err) {
 if (err) {
  console.log(err)
  return
 }
 console.log('Listening at http://localhost:' + (8081) + '\n')
})

2. Create a new db.json

{
 "getNewsList": [
  {
   "id": 1,
   "title": "新闻条目1新闻条目1新闻条目1新闻条目1",
   "url": "http://starcraft.com"
  },
  {
   "id": 2,
   "title": "新闻条目2新闻条目2新闻条目2新闻条目2",
   "url": "http://warcraft.com"
  },
  {
   "id": 3,
   "title": "新闻条3新闻条3新闻条3",
   "url": "http://overwatch.com"
  },
  {
   "id": 4,
   "title": "新闻条4广告发布",
   "url": "http://hearstone.com"
  }
 ],
 "login": {
  "username": "yudongdong",
  "userId": 123123
 },
 "getPrice": {
  "amount": 678
 },
 "createOrder": {
  "orderId": "6djk979"
 },
 "getOrderList": {
  "list": [
   {
    "orderId": "ddj123",
    "product": "数据统计",
    "version": "高级版",
    "period": "1年",
    "buyNum": 2,
    "date": "2016-10-10",
    "amount": "500元"
   },
   {
    "orderId": "yuj583",
    "product": "流量分析",
    "version": "户外版",
    "period": "3个月",
    "buyNum": 1,
    "date": "2016-5-2",
    "amount": "2200元"
   },
   {
    "orderId": "pmd201",
    "product": "广告发布",
    "version": "商铺版",
    "period": "3年",
    "buyNum": 12,
    "date": "2016-8-3",
    "amount": "7890元"
   }
  ]
 }
}

3. Access through localhost:8081/api/getNewsList
