详解vue2.0模拟后台json数据

const express = require('express')
const app = express()//请求server
var appData = require('../db.json')//加载本地数据文件
var news = appData.getNewsList//获取对应的本地数据
var products = appData.getproductList
var boards = appData.getBoardList
var apiRoutes = express.Router()
app.use('/api', apiRoutes)

  compress: true,

  },
  
//在这里添加，记得前面加上逗号不然会报错
