最新的vue裏dev-server.js被替換成了webpack-dev-conf.jsvue
在模擬後臺數據的時候直接在webpack-dev-conf.js文件中修改webpack
第一步,在const portfinder = require(‘portfinder’)後添加web
//第一步express
const express = require('express') const app = express()//請求server var appData = require('../data.json')//加載本地數據文件 var seller = appData.seller//獲取對應的本地數據 var goods = appData.goods var ratings = appData.ratings var apiRoutes = express.Router() app.use('/api', apiRoutes)//經過路由請求數據
第二步:找到devServer,在裏面加上before()方法npm
devServer: { clientLogLevel: 'warning', historyApiFallback: true, hot: true, 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, },
//第二步找到devServer,在裏面添加json
before(app) { app.get('/api/seller', (req, res) => { res.json({ errno: 0, data: seller })//接口返回json數據,上面配置的數據seller就賦值給data請求後調用 }), app.get('/api/goods', (req, res) => { res.json({ errno: 0, data: goods }) }), app.get('/api/ratings', (req, res) => { res.json({ errno: 0, data: ratings }) }) } }
提供一個json.data數據api

PS:安全
全部的修改配置都須要從新啓動運行命令的:npm run dev才能生效(很重要,不然沒法請求到數據)app
