现在升级后的vue没有dev-server.js和dev-client.js,可以通过以下方式模拟后台数据:
1.找到webpack.dev.conf.js这个文件,在const portfinder = require(‘portfinder‘)后面添加以下代码:
1 const express = require(‘express‘) 2 const app = express()//请求server 3 var appData = require(‘../data.json‘)//加载本地数据文件 4 var seller = appData.seller//获取对应的本地数据 5 var goods = appData.goods 6 var ratings = appData.ratings 7 var apiRoutes = express.Router() 8 app.use(‘/api‘, apiRoutes)//通过路由请求数据 9 10 devServer: { 11 clientLogLevel: ‘warning‘, 12 historyApiFallback: { 13 rewrites: [ 14 { from: /.*/, to: path.posix.join(config.dev.assetsPublicPath, ‘index.html‘) }, 15 ], 16 }, 17 hot: true, 18 contentBase: false, // since we use CopyWebpackPlugin. 19 compress: true, 20 host: HOST || config.dev.host, 21 port: PORT || config.dev.port, 22 open: config.dev.autoOpenBrowser, 23 overlay: config.dev.errorOverlay 24 ? { warnings: false, errors: true } 25 : false, 26 publicPath: config.dev.assetsPublicPath, 27 proxy: config.dev.proxyTable, 28 quiet: true, // necessary for FriendlyErrorsPlugin 29 watchOptions: { 30 poll: config.dev.poll, 31 }, 32 //以下是添加的代码: 33 before(app) { 34 app.get(‘/api/seller‘, (req, res) => { 35 res.json({ 36 errno: 0, 37 data: seller 38 })//接口返回json数据,上面配置的数据seller就赋值给data请求后调用 39 }), 40 app.get(‘/api/goods‘, (req, res) => { 41 res.json({ 42 errno: 0, 43 data: goods 44 }) 45 }), 46 app.get(‘/api/ratings‘, (req, res) => { 47 res.json({ 48 errno: 0, 49 data: ratings 50 }) 51 }) 52 } 53 54 55 },
2.运行npm run dev重启项目(注意,不重启,项目是不起效的):

3.在地址栏测试(以下就是获取到data.json里的数据):
