return QFile::copy from web

Question

When moving files around locally within my project I'm able to use

return QFile::copy(fromPath, toPath);

I need to do something similar but with the fromPath being located on the web.

What is the best way to accomplish this?

Answer 1

QFile works with local file only.

If you want to copy remote file from web, then you need to download it using QNetworkAccessManager

Answer 2

Install on your source and destination machine ssh. Then do a scp via QProcess. This is one way. The best? Depends on your requirements. You can also write a program for your destination machine, which accepts incoming TCP connections from your source machine. Then you connect via QTcpSocket and send your data. Qt4 has a QFtp class. Never used it. Is also a dead end, since it does not exist anymore in Qt5. But maybe it is good enough for your current needs.

I hope you did not expect a more specific answer. There is not 'remoteQFile::copy' command. And there is no general 'best way'.
