issue in downloading using QNetworkAccessManager

[ejoshva]

I am trying to download from an url using QNetworkAccessManager.

void qmlinterface::onSyncBooks(QString isbn,QString chapNo)
{
       QNetworkAccessManager *manager = new QNetworkAccessManager(this);
        connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(testDownload(QNetworkReply*)));
        QUrl serviceUrl = QUrl("http://172.16.14.41/mod_open1/download_quiz.php");
 
        QByteArray postData;
        postData.append("isbn="+isbn);
        postData.append("&user_mail="+userName);
        postData.append("&section_id="+chapNo);
 
        QNetworkRequest request(serviceUrl);
        manager->post(request, postData);
 }
 void qmlinterface::testDownload(QNetworkReply *pReply)
{
    qDebug()<<"error : "<<pReply->errorString();
    downloadedData  = pReply->readAll();
     qDebug()<<"downloadedData size : "<<downloadedData.size();
    pReply->deleteLater();
   addSyncDetailsToBookPath();
 
}

void qmlinterface::onSyncBooks(QString isbn,QString chapNo)
{
       QNetworkAccessManager *manager = new QNetworkAccessManager(this);
        connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(testDownload(QNetworkReply*)));
        QUrl serviceUrl = QUrl("http://172.16.14.41/mod_open1/download_quiz.php");

        QByteArray postData;
        postData.append("isbn="+isbn);
        postData.append("&user_mail="+userName);
        postData.append("&section_id="+chapNo);

        QNetworkRequest request(serviceUrl);
        manager->post(request, postData);
 }
 void qmlinterface::testDownload(QNetworkReply *pReply)
{
    qDebug()<<"error : "<<pReply->errorString();
    downloadedData  = pReply->readAll();
     qDebug()<<"downloadedData size : "<<downloadedData.size();
    pReply->deleteLater();
   addSyncDetailsToBookPath();

}
