I need to upload a file to a secure host using POST method. This is the code I tried (the file may have either text content or it may be an image. In case of image, as I see here, I can set the ContentTypeHeader to QVariant("image/jpeg"). So I will try that later. Now I am trying to upload a plain text file):
QUrl url(urlString); //typical secure host url - myhost.com/logs?key=<filename>&dsn=<some_dsn>&id=<id>&format=<format>
QNetworkRequest request(url);
QSslConfiguration config = request.sslConfiguration();
config.setPeerVerifyMode(QSslSocket::VerifyNone);
config.setProtocol(QSsl::TlsV1_0);
request.setSslConfiguration(config);
QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);
QHttpPart imagePart;
imagePart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("text/xml"));
imagePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"text\""));
QFile *file = new QFile(QString::fromStdString(fPathToFile));
file->open(QIODevice::ReadOnly);
imagePart.setBodyDevice(file);
file->setParent(multiPart); // we cannot delete the file now, so delete it with the multiPart
multiPart->append(imagePart);
QNetworkAccessManager manager;
QNetworkReply *reply = manager.post(request, multiPart);
connect(reply, SIGNAL(finished()), this, SLOT(onGetReply()));
connect(reply, SIGNAL(error(QNetworkReply::NetworkError)), SLOT(onError(QNetworkReply::NetworkError)), Qt::QueuedConnection);
multiPart->setParent(reply);
I have a simple qDebug in the attached slots, the code never ever comes there (and of course the file does not get uploaded correctly). I can't understand why, it should be either a success, or a failure, so it should come to one of the slots at least. I suspect that I have to set the certificates correctly. But I am not able to find out how. I went though the solutions posted here, it asks for password, and none is needed here, so I don't know what to provide there. I ran this command:
openssl s_client -showcerts -connect <myhost>:443 </dev/null
This is the output I get:

I can't understand how to set the certs from this output. How do I upload the file correctly to my host?
P.S I also have the .pem file corresponding to my host, that was obtained in the browser by hitting htts://myhost.com and then clicking the padlock icon and downloading the file from the popup shown. That comes out to be different that the one obtained above.
