vue 模拟数据

一、express模拟数据
webpack.dev.config.js中

const express = require('express')
const app = express()

const appData = require('../data.json')

const seller = appData.seller
const goods = appData.goods
const ratings = appData.ratings

const apiRoutes = express.Router()

const devWebpackConfig = merge(baseWebpackConfig, {
  ...
devServer: {
  ...
  watchOptions: {
    poll: config.dev.poll,
  },
  before (apiRoutes) {
    apiRoutes.get('/api/seller', function (req, res) {
        res.json({
          erron: 0,
          data: seller
        }) 
      })
  }
}）
