//第一步 const portfinder = require('portfinder'),在后面加上
const express = require('express');
const app = express();//請求server
const appData = require('../data.json');//加載本地數據文件
 
const goodsList = appData.goodsList;//獲取對應的本地數據
 
const apiRoutes = express.Router();
app.use('/api', apiRoutes);//通過路由請求數據

 //第二步找到devServer,在里面添加
    before(app) {
 
      app.get('/api/goodsList', (req, res) => {
        res.json({
          errno: 0,
          data: goodsList
        })//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
      })
 
    }

 /*請求Json數據*/
  const ERR_OK = 0;
 
  export default {
      data() {
        return {
          goodsList:[]
        }
      },
      created() {
        this.$http.get('/api/goodsList').then((response) => {
          response = response.body;
