How can i send file over http with Qt?

[Yaldiz]

Hi,

I have .bin file and i want to upload this file via http i tried following code, but not happened anything.

QFile* file = new QFile("C:/Users/Hp/Desktop/FileTest/2022-12-16 15-09-21.bin");
QHttpMultiPart * multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);
QHttpPart filePart;

file->open(QIODevice::ReadOnly);

filePart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("application/zip")); //or whatever type of your file.
filePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"bin\""));
filePart.setHeader(QNetworkRequest::ContentLengthHeader, file->size());
file->setParent(multiPart);

filePart.setBodyDevice(file);
multiPart->append(filePart);

QNetworkAccessManager mgr;
QNetworkRequest req(QUrl("some/url"));
//req.setRawHeader("Authorization", ("Token <token>"));
[[maybe_unused]] QNetworkReply * reply = mgr.post(req, multiPart);

Thanks for helps.

but not happened anything.

Did you check what the reply object returned had to say? Did you receive the QNetworkAccessManager/QNetworkReply::finished signals? What about the file->open() call just to be sure? Is the Url http and not https?

Hi,

Beside @JonB suggestions, what is the lifetime of mgr ?
You also don't do any error checks which is a bad idea.
