最新的vue里dev-server.js被替換成了webpack-dev-conf.js
在模擬后台數據的時候直接在webpack-dev-conf.js文件中修改
第一步，在const portfinder = require(‘portfinder’)后添加
//第一步 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)//通過路由請求數據
第二步：找到devServer,在里面加上before（）方法
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,在里面添加 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請求后調用 }), 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
