使用node中的express解决vue-cli加载不到dev-server.js的问题

import VueResource from ‘vue-resource‘
Vue.use(VueResource)

#webpack.dev.conf.js
// 首先在const portfinder = require(‘portfinder‘)后添加

// 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 goods = appData.result

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

#webpack.dev.conf.js
// 在devServer选项中添加以下内容
before(app) {
  app.get(‘/api/someApi‘, (req, res) => {
    res.json({
      // 这里是你的json内容
    })
  })
}

#webpack.dev.conf.js
apiRoutes.post(‘/foods‘, function (req, res) { //注意这里改为post就可以了
  res.json({
    error: 0,
    data: foods
  });
})
// 在组件里面
#...vue
created () {
 this.$http.post(‘http://localhost:8080/api/foods‘).then((res) => {
  console.log(res)
