python sftp to determine if a file exists
SFTP supports the usual FTP commands (chdir, mkdir , etc.), so use these commands:
sftp = paramiko.SFTPClient.from_transport(transport)
try:
sftp.chdir(remote_path) # Test if remote_path exists
except IOError:
sftp.mkdir(remote_path) # Create remote_path
sftp.chdir (remote_path)
sftp.put(local_path, '.') # At this point, you are in remote_path in either case
sftp.close()
To fully emulate mkdir -p , you can use remote_path recursively:
import os.path
def mkdir_p(sftp, remote_directory):
"""Change to this directory, recursively making new folders if needed.
Returns True if any folders were created."""
if remote_directory == '/':
# absolute path so change directory to root
sftp.chdir ('/')
return
if remote_directory == '':
# top-level relative directory must exist
return
try:
sftp.chdir(remote_directory) # sub-directory exists
except IOError:
dirname, basename = os.path.split(remote_directory.rstrip('/'))
mkdir_p(sftp, dirname) # make parent directories
sftp.mkdir(basename) # sub-directory missing, so created it
sftp.chdir (basename)
return True
sftp = paramiko.SFTPClient.from_transport(transport)
mkdir_p(sftp, remote_path)
sftp.put(local_path, '.') # At this point, you are in remote_path
sftp.close()
Of course, if remote_path also contains a remote filename, then it needs to be split, and that directory is passed to mkdir_p, using the filename instead of '.'. in sftp.put.
