            button.btn.btn-default(type="submit") 录入

app.js

var express = require('express')
var bodyParser = require('body-parser')
var path = require('path')
var mongoose = require('mongoose')
var _ = require('underscore')
var Movie = require('./models/movie')
var port = process.env.NODE_ENV || 3000
var app = express()

app.set('views', './views/pages')
app.set('view engine', 'jade')
app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())
app.use(express.static(path.join(__dirname, 'bower_components')))
app.listen(port)

console.log('service started on port:' + port)

// admin post movie
app.post('/admin/movie/new', function(res, req){
  var id = req.body.movie._id
  var movieObj= req.body.movie
  var _movie

  if (id !== 'undefined') {
    Movie.findById(id, function(err, movie) {
      if (err) {
        console.log(err)
      }

      _movie = _.extend(movie, movieObj)
      _movie.save(function(err, movie) {
        if(err){
          console.log(err)
        }

        res.redirect('/movie/' + movie._id)
      })
    })
  }
  else {
    _movie = new Movie({
      doctor: movieObj.doctor,
      title: movieObj.title,
      country: movieObj.country,
      language: movieObj.language,
      year: movieObj.year,
      poster: movieObj.poster,
      summary: movieObj.summary,
      falsh: movieObj.falsh
    })

    _movie.save(function(err, movie) {
      if(err) {
        console.log(err)
      }

      res.redirect('/movie/' + movie._id)
    })
  }
})

已经把bodyparser单独安装在本地目录下，在运行时，post数据到地址“/admin/movie/new”，获取不到数据，req是有数据的，但是req.body为undefined不知道是哪里除了问题！！！
