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servervar 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：
