file->open(QIODevice::ReadOnly);
QHttpMultiPart *multi_part = new QHttpMultiPart(QHttpMultiPart::FormDataType);
QHttpPart image_part;
image_part.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("image/jpg"));
image_part.setHeader(QNetworkRequest::ContentDispositionHeader
    , QVariant(QString("form-data; name=\"file\";filename=\"testfile.jpg\";"));
