使用nodejs上传文件，使用dropzone进行表达和角度

Question

I'm having trouble getting the file recognized server side with node.

Specifically when accessing request data, (req.files or req.body)

Here are some snippets if someone has any advice.

html :

<form action="/upload" class="dropzone" drop-zone id="file-dropzone"></form>

angular controller :

'use strict';

angular.module('app')
  .controller('SampleCtrl', function ($scope, $http) {


  })

  .directive('dropZone', function() {
    return function(scope, element, attrs) {
     $(element).dropzone({ 
        url: "/upload",
        maxFilesize: 100,
        maxThumbnailFilesize: 5
    });
  }
});

node router :

'use strict';

var express = require('express');
var controller = require('./import.controller');

var router = express.Router();

router.post('/', controller.import);

module.exports = router;

node controller :

'use strict';

var express = require('express'),
    _ = require('lodash'),
    fs = require('fs'),
    path = require('path'),
    multer = require('multer'),
    bodyParser = require('body-parser'),
    app = express();

app.use(bodyParser.urlencoded({extended: true}));

exports.import = function(req, res) {
    console.log(req.files); // responds with 'undefined'
    console.log(req.body); // responds with {}
};

thanks in advance

You have to actually use the file upload middleware to get express to unpack that part of the request. From the multer docs:

var express = require('express')
var multer  = require('multer')

var app = express()
app.use(multer({ dest: './uploads/'}));

console.log(req.body)
console.log(req.files)
