简单实现nodejs上传功能

http.createServer(function(req,res) {
if (req.url == '/index' && req.method.toLowerCase() == 'post') {
// parse a file upload
var form = new formidable.IncomingForm();
form.uploadDir = './upload';

form.parse(req,function(err,fields,files) {
console.log(fields);
console.log(files);
});

}
}).listen(3001);
