How to send an http POST request with a picture

Hi!
How to send an http POST request with a picture?
I tried this:

QHttpMultiPart * data = new QHttpMultiPart();
    QHttpPart part;
    part.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("text/plain"));
    part.setHeader(QNetworkRequest::ContentDispositionHeader,  QVariant("form-data; name=\"text\""));
    part.setBody("Hello there!");
    data->append(part);
    QHttpPart imagePart;
    imagePart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("image/jpeg"));
    imagePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("multipart/form-data; name=\"image\"; filename=\"1.jpg\""));
    imagePart.setRawHeader("Content-Transfer-Encoding","binary");
 
    QFile *file = new QFile("E:/images/devine_icons_part_2_by_ipapun-d2c0w18/Gaia/PNG/Dark/1.png");
    if(file->open(QIODevice::ReadOnly))
        qDebug()<<"file opened";
    qDebug()<<"file:"<<file->size();
    imagePart.setBodyDevice(file);
    data->append(imagePart);
    file->close();  
    myApiQuery.post(request, data);

But I get an error: QIODevice::read (QFile, "E:\images\devine_icons_part_2_by_ipapun-d2c0w18\Gaia\PNG\Dark\1.png"): device not open

Hi,

You are closing before the request could even be processed.

Look at the example of the QHttpMultiPart documentation.
