详解vueexpress启动数据服务

var apiServer = express()
var bodyParser = require('body-parser')
apiServer.use(bodyParser.urlencoded({ extended: true }))
apiServer.use(bodyParser.json())
var apiRouter = express.Router()
var fs = require('fs')
apiRouter.route('/:apiName')
.all(function (req, res) {
 fs.readFile('./db.json', 'utf8', function (err, data) {
  if (err) throw err
  var data = JSON.parse(data)
  if (data[req.params.apiName]) {
   res.json(data[req.params.apiName]) 
  }
  else {
   res.send('no such api name')
  }

 })
})

apiServer.use('/api', apiRouter);
apiServer.listen(port + 1, function (err) {
 if (err) {
  console.log(err)
  return
 }
 console.log('Listening at http://localhost:' + (port + 1) + '\n')
})

 proxyTable: {
    '/api/':'http://localhost:8081/'
  },
