最新的vue沒有dev-server.js文件,如何進行後臺數據模擬?

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
