vue-cli的build的資料夾下沒有dev-server.js檔案，怎麼配置本地資料

因為最新版本的vue-cli已經放棄dev-server.js，只需在webpack.dev.conf.js配置就行

新版webpack.dev.conf.js配置如下：

上面一張圖是初始稿，只寫引入本地資料那一條程式碼即可，
如下圖：

需要安裝express依賴
npm install express --save-dev 不需要安裝express

在const portfinder = require(‘portfinder’)後新增

const express = require
 
('express') // 不需要
const app = express() // 不需要
var appData = require('../src/goods.json') //載入本地資料檔案
var router = express.Router() // 不需要
app.use('/api', router)  // 不需要

//然後找到devServer,在裡面新增
//介面返回json資料，下面配置的資料appData就賦值給data請求後呼叫
    before(app) {
      app.get('/api/appData', (req, res) => {
        res.json({
          error: 0
 
,
          data: appData
        })
      })
    },

相關檔案詳細如下：

本地src目錄下

  "error": 0,
  "data": {
    "status": "0",
    "result": [
