    Hi Qt Community! I am actually experiencing a problem while trying to use QHttpMultipart to upload the file to a nodejs server using express and Multer. I am sure that the server is running properly, the problem might be on the QHttpMultipart side. Here is the code for my nodejs server and the QHttpMultipart upload part.
    node server:

    const express = require('express');
const sqlite3 = require('sqlite3').verbose();
const multer = require('multer');
const app = express();
const upload = multer({ dest: './tmp/' })
app.use(express.static('.'));

let db = new sqlite3.Database('./resources/files.sqlite');

app.get('/',(req, res)=>{
    res.status(200).send("<form action=\"/upload\" enctype=\"multipart/form-data\" method=\"post\">\n" +
        "    <div class=\"form-group\">\n" +
        "        <input type=\"file\" class=\"form-control-file\" name=\"zip\">\n" +
        "        <input type=\"submit\" value=\"Get me the stats!\" class=\"btn btn-default\">\n" +
        "    </div>\n" +
        "</form>")
})

app.get('/pcbs',(req,res) => {
    db.all("SELECT id, name, png, gerber, drill FROM PCBs LIMIT 30",[], (err, rows)=>{
        if (err) throw err;
        res.json({
            "pcbs": rows
        })
    })
})

app.post('/upload',upload.single("zip"),(req,res,next)=>{
        console.log(req);
        res.status(200).send("successfully uploaded the file!")
});

const PORT = 4200;
app.listen(PORT, ()=>{
    console.log(`App running on port ${PORT}`);
});

    Here is the qt code:

    QString file_path = QFileDialog::getOpenFileName(this, "Choose zip you want to upload",QDir::currentPath(),"Compressed File (*.zip)");
    qDebug() << file_path;
    QNetworkRequest upload_request;
    upload_request.setUrl(urlBase + "upload");
    QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);

    QHttpPart zipPart;
    zipPart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("application/zip"));
    zipPart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"zip\""));
    QFile *file = new QFile(file_path);
    file->open(QIODevice::ReadOnly);
    zipPart.setBodyDevice(file);
    file->setParent(multiPart); // we cannot delete the file now, so delete it with the multiPart

    multiPart->append(zipPart);

    QNetworkAccessManager *upload_manager = new QNetworkAccessManager(this);

    QNetworkReply *reply = upload_manager->post(upload_request, multiPart);
    connect(upload_manager,&QNetworkAccessManager::finished,[this, reply,file](){
        QString data = (QString)reply->readAll();
        QJsonDocument jsonResponse = QJsonDocument::fromJson(data.toUtf8());
        QJsonObject jsonObject = jsonResponse.object();
        qDebug() << jsonObject["message"].toString();
        file->close();
    });

    Any advice would be helpful! Thank you very much!

      @Bonnie Okay I think I got the raw data. Correct me if I am wrong.

      @never0lie
      Looks like the only difference in the file part is the Content-Disposition header.
      As you can see, the one from your successful upload is QVariant("form-data; name=\"zip\"; filename=\"3-half-bridges-board_drill.zip\"").
      I'm not sure if this is the key part (to have a filename?) but you can start with that.

        In the beginning, I mentioned that the server is working properly. Here is the HTTP request printed from the node server when the file upload was working properly. I would post the request when using QHttpMultipart in a second post too due to character limit. I think the big difference is at the end around the body part:

            Apparently your server needs form-data named "file".
            So at least it should be QVariant("form-data; name=\"file\"").
            Or maybe also add other params like QVariant("form-data; name=\"file\"; fieldname=\"zip\"").

              @Bonnie Thank you for your advice! I tried that however it didn't work. The only difference is that the beginning part of the last body field changed from

              body: [Object: null prototype] {
    zip: 'PK\x03\x04\x14\x00\x00\x00\x00\x00\x04z\x0BIJH\x18"�\x02\x00\x00�\x02\x00\x007\x00\x00\x00358f7f9cd50126e4_14709282650000_drills-plated-all.drillM48\r\n' +
      'M71,TZ\r\n' +

              to

              body: [Object: null prototype] {
	    file: 'PK\x03\x04\x14\x00\x00\x00\x00\x00\x04z\x0BIJH\x18"�\x02\x00\x00�\x02\x00\x007\x00\x00\x00358f7f9cd50126e4_14709282650000_drills-plated-all.drillM48\r\n' +

              and the file upload still fails.
              I just realized there is a major difference in the successful upload, the successful body part looks like

              body: [Object: null prototype] {},
  file: {
    fieldname: 'zip',
    originalname: '3-half-bridges-board_drill.zip',
    encoding: '7bit',
    mimetype: 'application/zip',
    destination: './tmp/',
    filename: '13289ddcca83407a7770faeda5bd62a4',
    path: 'tmp/13289ddcca83407a7770faeda5bd62a4',
    size: 851
  },

              I don't know why this happens. Can someone explain? Thanks!

                Oh, ok, I didn't read your code and log carefully enough, that's just my working code for some server...I may need to take it back...
                Your successful upload seems to have an empty body, but with QHttpPart, the data should always go to the body.
                Is there any way to print the raw / unparsed data?

                    Looks like the only difference in the file part is the Content-Disposition header.
                    As you can see, the one from your successful upload is QVariant("form-data; name=\"zip\"; filename=\"3-half-bridges-board_drill.zip\"").
                    I'm not sure if this is the key part (to have a filename?) but you can start with that.

                      @Bonnie Thank you so much! That was exactly the problem! I can successfully upload the file with QHttpMultipart right now!
