I have used the code below to download a file using http: No errors.

But the file is not get downloaded::

  QUrl url = QUrl::fromUserInput(strUrl);
 
      QFileInfo fileInfo(url.path());
 
      QString fileName=fileInfo.fileName();
  
      if (QFile::exists(fileName)) {
  
      QMessageBox::information(this, tr("HTTP"),
  
      tr("There already exists a file called %1 in "
  
      "the current directory.")
 .arg(fileName));
   
      }
 
       
 
      file = new QFile(fileName);
 
      if (!file->open(QIODevice::WriteOnly)) {
 
      QMessageBox::information(this, tr("HTTP"),
 
      tr("Unable to save the file %1: %2.")
 
      .arg(fileName).arg(file->errorString()));
 
      delete file;
 
      file = 0;
      }
 
       
 
      file.setFileName(fileName);
     file.open(QIODevice::WriteOnly);
 
      QHttp http;
    QEventLoop loop;
    QFile file;
    QObject::connect(&http, SIGNAL(done(bool)), &loop, SLOT(quit()));
 
    file.setFileName(filename);
    file.open(QIODevice::WriteOnly);
 
    http.setHost(url.host(), url.port(80));
    http.get(url.toEncoded(QUrl::RemoveScheme | QUrl::RemoveAuthority), 
&file);
 
    loop.exec();

You're not checking the error returns on the APIs connect and get (among others). Check what the error code is, and then post here again when you have that information.

Error code is 0 for both the statements.

Is 0 a success code or a failure code? In any case, look at the Qt documentation and check why the API could fail.
