vue-cli模拟数据，新版本升级后， 没有dev-server 文件了

我们可以修改

因为最新版本的vue-cli已经放弃dev-server.js，只需在webpack.dev.conf.js配置就行

新版webpack.dev.conf.js配置如下：

代码1：

//模拟数据：1.首先
// nodejs开发框架express，用来简化操作
const express = require('express')
// 创建node.js的express开发框架的实例
const app = express()
// 引用的json地址
var appData = require('../data.json')
// json某一个key
var seller = appData.seller
var goods = appData.goods
var ratings = appData.ratings

var apiRoutes = express.Router()
app.use('/api', apiRoutes)

 

代码2：

//模拟数据：2.配置项
    before(app){
      app.get('/seller', (req, res) => {
        res.json({
          errno: 0,
          data: seller
        })
      })
      app.get('/goods', (req, res) => {
        res.json({
          errno: 0,
          data: goods
        })
      })
      app.get('/ratings', (req, res) => {
        res.json({
          errno: 0,
          data: ratings
        })
      })
    }
  },
