Using wildcards in file names using Python's SCPClient library

问题

I want to copy files from remote machine using Python script to my local machine. I only know the extension of the file names so I want to use wildcards to express the file name.

In addition, I want to use the SCPClient Python library and not the os.system directly as suggested in the question titled using wildcards in filename in scp in python

But when I run the following code:

from paramiko import SSHClient
import paramiko
from scp import SCPClient

with SSHClient() as ssh:
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect('10.10.100.5', username= 'root', password='Secret')
    with SCPClient(ssh.get_transport()) as scp:
        scp.get(remote_path='/root/*.py', local_path='.')

I get an exception

scp.SCPException: scp: /root/*.py: No such file or directory

Running from shell works just fine

scp root@10.10.100.5:/root/*.py .

回答1:

You need to add sanitize to your get_transport():

with SCPClient(ssh.get_transport(), sanitize=lambda x: x) as scp:
        scp.get(remote_path='/root/*.py', local_path='.')

Otherwise wildcards are treated literally.
