node.js中的file upload只是不停地上传？

我正在学习这个教程： http : //vimeo.com/17442755 。 它教你如何使用node.js上传文件。

这是app.js中的完整代码：

var express = require('express'); var multipart = require('./multipart'); var fs = require('fs'); var app = express.createServer(); app.configure(function() { app.use(express.logger()); app.use(express.bodyParser()); app.use(express.methodOverride()); app.use(express.static(__dirname + '/static')); }); app.configure('development', function () { app.use(express.logger()); app.use(express.errorHandler({ dumpExceptions: true, showStack: true })); }); app.configure('production', function () { app.use(express.errorHandler()); }); app.set('views', __dirname + '/views'); app.set('view engine', 'jade'); app.get('/', function(req, res) { res.render('root'); }); var products = require('./products'); app.get('/products', function(req, res) { res.render('products/index', {locals: { products: products.all }}); }); app.get('/products/new', function(req, res) { res.render('products/new', {locals: { product: req.body && req.body.product || products.new }}); }); app.post('/products', function(req, res) { var id = products.insert(req.body.product); res.redirect('/products/' + id); }); app.get('/products/:id', function(req, res) { var product = products.find(req.params.id); res.render('products/show', {locals: { product: product }}); }); app.get('/products/:id/edit', function(req, res) { var product = products.find(req.params.id); res.render('products/edit', {locals: { product: product }}); }); app.put('/products/:id', function(req, res) { var id = req.params.id; products.set(id, req.body.product); res.redirect('/products/'+id); }); /* Photos */ app.get('/photos/new', function(req, res) { res.render('photos/new'); }); app.post('/photos', function(req, res) { req.setEncoding('binary'); var parser = multipart.parser(); parser.headers = req.headers; parser.onPartBegin = function(part) { ws = fs.createWriteStream(__dirname + '/static/upload/photos/' + part.filename); ws.on('error', function(err) { throw err; }); }; parser.onData = function(data) { ws.write(data); }; parser.onPartEnd = function() { ws.end(); parser.close(); res.send('File sucessfully uploaded.'); }; req.on('data', function(data) { parser.write(data); }); }); app.listen(4000); 

现在，当我尝试上传文件，浏览器只是永远加载。

任何build议来解决这个问题？

Answer 1

你正在使用multipart.js这是破碎的：

 Current State Pre-pre-alpha. Almost nothing is here, and what is here is likely completely broken. If you are asking about this, you probably ought to check out Felix's node-formidable library. 

正如Isaacs（多部分的作者）所build议的那样，您应该真正使用node-formidable来代替。

Answer 2

截至目前它是自动的。 如果您使用的是Express或connect.io，请确保在处理POST主体时以及何时使用req.files。
