最新的vue里dev-server.js被替換成了webpack-dev-conf.js
在模擬后臺數據的時候直接在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

PS:
所有的修改配置都需要重新啟動運行命令的:npm run dev才能生效(很重要,否則無法請求到數據)
