node.js中的文件上傳只是無限期地上傳？

Question

我在關注本教程：http://vimeo.com/17442755。 它教你如何使用node.js上傳文件。

這是一個完整的代碼在app.js：

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); 

現在，當我嘗試上傳文件，瀏覽器只是不停地裝載到永遠。

任何建議來解決這個問題？

Answer 1

您正在使用multipart.js在被折斷：

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. 

正如艾薩克斯（多的作者）建議，你應該使用node-formidable代替。

Answer 2

截至目前它是自動的。如果您使用Express或connect.io，請確保您在處理POST主體時以及何時使用req.files。
