vue+webpack模拟后台数据的示例代码

一、在webpack-dev-conf.js文件中：

1、在const portfinder = require(‘portfinder')后添加如下内容

const express = require('express')
const app = express() //请求server
var appdata = require('../mock/goods.json') //加载本地数据文件
var apiroutes = express.router()
app.use(apiroutes) //通过路由请求数据

2、找到devserver,在里面加上before（）方法

devserver: {
 clientloglevel: 'warning',
 historyapifallback: {
  rewrites: [
   { from: /.*/, to: path.posix.join(config.dev.assetspublicpath, 'index.html') },
  ],
 },
 hot: true,
 contentbase: false, // since we use copywebpackplugin.
 compress: true,
 host: host || config.dev.host,
 port: port || config.dev.port,
 open: config.dev.autoopenbrowser,
 overlay: config.dev.erroroverlay ? { warnings: false, errors: true } : false,
 publicpath: config.dev.assetspublicpath,
 proxy: config.dev.proxytable,
 quiet: true, // necessary for friendlyerrorsplugin
 watchoptions: {
  poll: config.dev.poll,
 },
 before(app) {
  app.get('/goods', (req, res) => {
   res.json(appdata)
  })
 }
},

二、在goods.json文件：

{
 "status": "0",
 "msg": "",
 "result": [
  {
   "productid": "100001",
   "productname": "小米6",
   "productprice": "2499",
   "productimg": "1.jpg"
  },{
   "productid": "100002",
   "productname": "音箱",
   "productprice": "999",
   "productimg": "2.jpg"
  },{
   "productid": "100003",
   "productname": "电脑",
   "productprice": "199",
   "productimg": "3.jpg"
  }
 ]
}

三、在goodslist.vue文件中：
