multiparty 模块，请求体已经解析了为什么req.files还为undefined？？

Question

下面代码里使用app.use(bodyParser.json());app.use(bodyParser.urlencoded({ extended: false }));这应该已经解析了请求体啊，为什么req.files还是undefined？var express = require('express');var bodyParser = require('body-parser');var multiparty = require('multiparty');var app = express();app.listen(3000);// view engine setupapp.set('views', path.join(__dirname, 'views'));app.set('view engine', 'ejs');app.set('photos',__dirname+'/public/photos');app.use(bodyParser.json());app.use(bodyParser.urlencoded({ extended: false }));app.use(express.static(path.join(__dirname, 'public')));app.get('/upload',photos.form);app.route('/upload').post(function(req,res){    var multiparty = require('multiparty');    var form = new multiparty.Form();//新建表单    //设置编辑    form.encoding = 'utf-8';    //表单解析    form.parse(req, function(err,fields,files) {        //报错处理        if(err){            return;        }        console.log("files: ", files);        var oldpath=files.imgFile[0]['path'];    });});module.exports = app;
