Http Posting using QNetworkAccessManager

[Mohammadhzp]

Hello
I'm facing another problem
it's about uploading file through HTTP posting
this is my code

from PyQt4 import QtCore, QtGui, QtNetwork
import sys
class Window(QtGui.QWidget):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)
 
        self.netaccess = QtNetwork.QNetworkAccessManager(self)
        self._uploaders = {}
        row = 1 #this number will change per upload in real program,this is just demo
        self.address = 'http://localhost/01/upload/demo.php'
        stream = QtCore.QFile('/home/patriot/icon.png')
        if stream.open(QtCore.QIODevice.ReadOnly):
            data = stream
 
            uploader = self._uploaders[row] = Uploader(row, self.netaccess)
 
            uploader.upload(data, self.address)
 
class Uploader(QtCore.QObject):
 
    def __init__(self, key, parent):
        QtCore.QObject.__init__(self, parent)
        self._key = key
        self._reply = None
 
 
    def upload(self, data, url):
        if self._reply is None:
 
            self._stream = data
 
            self._multiPart = QtNetwork.QHttpMultiPart(QtNetwork.QHttpMultiPart.FormDataType)
 
            fileName = QtCore.QFileInfo(self._stream.fileName()).fileName()
            key = 'file'
 
            imagePart = QtNetwork.QHttpPart()
            imagePart.setHeader(QtNetwork.QNetworkRequest.ContentDispositionHeader,
                     "form-data; name=\"%s\"; filename=\"%s\"" % (key, fileName))
            imagePart.setHeader(QtNetwork.QNetworkRequest.ContentTypeHeader,
                     'image/png')
            imagePart.setBodyDevice(self._stream)
 
            self._multiPart.append(imagePart)

            self._reply = self.parent().post(request, self._multiPart)
            self._reply.uploadProgress.connect(self.handleUploadProgress)
            self._reply.error.connect(self.handleError)
            self._reply.finished.connect(self.handleFinished)
 
 
 
    def handleUploadProgress(self, sent, total):
        if sent >= total:
            # prevent duplicated uploads
            self._reply.close()
