Can you share your code how you try to add the image as multi part?

void product::add(QString photos)
{
QString id=settings.value("id").toString();
qDebug() <<"id"<<id;

QString token=settings.value("token").toString();
qDebug() <<"token"<<token;

QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);

QHttpPart photo;
photo.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("image/*"));
photo.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"photo\""));
QFile *file = new QFile(photos);
file->open(QIODevice::ReadWrite);
photo.setBodyDevice(file);
file->setParent(multiPart);

multiPart->append(photo);

QUrl url("http://localhost:3070/auth/v1/product/Add");
QNetworkRequest request(url);
request.setRawHeader("x-access-token","" + token.toUtf8());
QNetworkAccessManager manager;
QNetworkReply *reply = manager.post(request, multiPart);
multiPart->setParent(reply);

while(!reply->isFinished())
{ qApp->processEvents(); }
}
