MOCK DATA -- node路由

前后端分离，有时候后端接口给的不是很及时，这就需要前端自己mock data，

本文讲的简单的node模拟数据 api路由跳转

首先有个data.js（json）文件，

路由：

配置在dev-server.js

require('./check-versions')()
var config = require('../config')
if (!process.env.NODE_ENV) process.env.NODE_ENV = JSON.parse(config.dev.env.NODE_ENV)
var path = require('path')
var express = require('express')
var webpack = require('webpack')
var opn = require('opn')
var proxyMiddleware = require('http-proxy-middleware')
var webpackConfig = require('./webpack.dev.conf')

// default port where dev server listens for incoming traffic
var port = process.env.PORT || config.dev.port
// Define HTTP proxies to your custom API backend
// https://github.com/chimurai/http-proxy-middleware
var proxyTable = config.dev.proxyTable

var app = express()
//router Start
var appData = require('../data.json');//获取data数据
var seller = appData.seller;　//获取详细数据
var goods = appData.goods;  //获取详细数据
var ratings = appData.ratings;  //获取详细数据

var apiRouter = express.Router();  //定义一个路由

apiRouter.get('/seller',function(req,res){//.get方法第一个参数 地址，第二个是个函数，传入requrice responce，responce返回json对象
  res.json({
    errno: 0,    //错误代码
    data: seller //数据
  });
});
apiRouter.get('/goods',function(req,res){
  res.json({
    errno: 0,
    data: goods
  });
});
apiRouter.get('/ratings',function(req,res){
  res.json({
    errno: 0,
    data: ratings
  });
});

app.use('/api',apiRouter);//加载路由  访问路径：根目录/api/seller  根目录/api/goods  根目录/api/ratings
//router End
var compiler = webpack(webpackConfig)

var devMiddleware = require('webpack-dev-middleware')(compiler, {
  publicPath: webpackConfig.output.publicPath,
  stats: {
    colors: true,
    chunks: false
  }
})

var hotMiddleware = require('webpack-hot-middleware')(compiler)
// force page reload when html-webpack-plugin template changes
compiler.plugin('compilation', function (compilation) {
  compilation.plugin('html-webpack-plugin-after-emit', function (data, cb) {
    hotMiddleware.publish({ action: 'reload' })
    cb()
  })
})

// proxy api requests
Object.keys(proxyTable).forEach(function (context) {
  var options = proxyTable[context]
  if (typeof options === 'string') {
    options = { target: options }
  }
  app.use(proxyMiddleware(context, options))
})

// handle fallback for HTML5 history API
app.use(require('connect-history-api-fallback')())

// serve webpack bundle output
app.use(devMiddleware)

// enable hot-reload and state-preserving
// compilation error display
app.use(hotMiddleware)

// serve pure static assets
var staticPath = path.posix.join(config.dev.assetsPublicPath, config.dev.assetsSubDirectory)
app.use(staticPath, express.static('./static'))

module.exports = app.listen(port, function (err) {
  if (err) {
    console.log(err)
    return
  }
  var uri = 'http://localhost:' + port
  console.log('Listening at ' + uri + '\n')

  // when env is testing, don't need open it
  if (process.env.NODE_ENV !== 'testing') {
    opn(uri)
  }
})

//获取详细数据
