I am trying to upload a .csv file on my server. Referring the documentation, i have written the following code. But, there is some problem and it's not working.

I am calling doUpload() for the upload action:

Qt Code: 
  1. uploadmanager::uploadmanager()
  2. {
  3.     connect(&manager, SIGNAL(finished(QNetworkReply*)),
  4.             SLOT(uploadFinished(QNetworkReply*)));
  5. }
  6.  
  7.  
  8. void uploadmanager::doUpload()
  9. {
  11.     QString message_d = QString("Unable to open file");
  12.     args<<"E:\\SMSAssassin\\spam_freq.csv";
  13.  
  14.     foreach (QString arg, args) {
  15.  
  16.        QFile file(arg);
  17.        if (!file.open(QIODevice::ReadOnly))
  18.        {
  19.            QMessageBox::information(this, "Error", message_d);
  20.            return;
  21.        }
  22.  
  23.     QNetworkRequest request;
  24.     request.setUrl(QUrl("http://ddd.myserver.com/smssp/uploads/"));
  25.     request.setHeader(QNetworkRequest::ContentTypeHeader,"application/x-www-form-urlencoded");
  26.     file.open(QIODevice::ReadOnly);
  27.     QByteArray fileBinaryData(file.readAll());
  28.     file.close();
  29.     QNetworkReply *reply = manager.put(request, fileBinaryData);
  30.  
  31.     currentUploads.append(reply);
  32. }
  33.  
  34. }
  35.  
  36. void uploadmanager::uploadFinished(QNetworkReply *reply)
  37. {
  38.     //QUrl url = reply->url();
  39.     if (reply->error())
  40.     {
  41.         QString message_er = QString("Error in Upload");
  42.         QMessageBox::information(this, "Err", message_er);
  43.     }
  44.     else
  45.     {
  46.         QString message_d = QString("Upload Complete");
  47.         QMessageBox::information(this, "Upload Complete", message_d);
  48.  
  49.     }
  50.  
  51.     currentUploads.removeAll(reply);
  52.     reply->deleteLater();
  53.  
  54.     if (currentUploads.isEmpty())
  55.         return;
  56.  
  57. }
