dev-server.js没了，webpack.dev.conf.js进行设置

mock数据
//首先
const express = require(‘express‘)
const app = express()
var appData = require(‘../data.json‘)
var seller = appData.seller
var apiRoutes = express.Router()
app.use(‘/api‘, apiRoutes)
//找到devServer,添加
before(app) {
  app.get(‘/api/seller‘, (req, res) => {
    res.json({
      // 这里是你的json内容
      errno: 0,
      data: seller
    })
  })
}

vue-resource 请求数据
首先
main.js中

import VueResource from ‘vue-resource‘;

Vue.use(VueResource);

然后

<script>
    export default {
        data() {
            return {
                myData:{}
            }
        },
        created() {      
            this.$http.get(url).then((response) => {
                // success
              this.myData = response.body.data;  --将数据转化为json形式，注意这里的this
            },(error) => {
                // error
                console.log(error)
            });
        }
    }
</script>
