Q:

Upload file via SSH2 protocol using QNetworkAccessManager

I need to upload an image file on server using ssh2 protocol on port 22. SSH2 protocol with QNetworkAccessManger is not popular on Google either. Here is my code.
QUrl uploadUrl("ssh2://192.168.10.227/var/www/html/img/"+mImgFile);

    uploadUrl.setUserName("xxxxxx");
    uploadUrl.setPassword("xxxxxx");
    uploadUrl.setPort(22);

    qDebug() << uploadUrl.toString();

    QNetworkRequest uploadReq(uploadUrl);

    mReply = mNetworkManager->put(uploadReq, &file);

    connect(mReply, SIGNAL(uploadProgress(qint64, qint64)), this, SLOT(uploadProgress(qint64, qint64)));

With URL-scheme as "ssh2" or "sftp" or "ssh2.sftp"; it outputs that Protocol is unknown. And the reason i used strange-looking "ssh2.sftp", is here(just a little php code to view).
I want to know whether ssh2 can be used with qnetworkaccessmanager at all? If yes, what is the correct URL-format to upload an image file?

A:

There is no SSH support in Qt, for example see
Howto implement SFTP with Qt/QNetworkAccessManager (C++) and How to easily establish an SSH connection in Qt?
The list of supported URL schemes in QNetworkAccessManager can be obtained by QNetworkAccessManager::supportedSchemes() that is ("ftp", "file", "qrc", "http", "https", "data") in default Qt releases (https is supported only if external OpenSSL library is found, since it is also not supplied with Qt).
So, it is still needed to use external C library libssh2 to work with SSH2 protocol using native sockets.
I found here that there was some old Qt extension LibQxt with Qt SSH support. However, it is no longer maintained.
