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：
