ganymed SSH2 analog similar FileZilla remote transfer file (based on SCP protocol)

In order to transfer files or directories, we use the Scpclient class in Ganymed SSH2, which implements the SCP command function.

The following code includes the ability to transfer a single file and transfer a directory:

The results of the operation are not posted.

When you transfer a directory, you simply traverse the file transfer recursively. The transmission of a single file can also be optimized, with a single file having large, small capacity after all.

The remote file directory also executes system commands to create.
Directory creation We used the mkdir-p, so that the system will automatically be created for us, even if the parents are not recorded.
