要通过 ssh 从远程文件夹下载所有文件，您可以使用 ftp.listdir() 列出文件，然后为每个文件使用 ftp.get() :

#!/usr/bin/env python
import os
import sys
from contextlib import closing

from paramiko import SSHConfig, SSHClient

# specify hostname to connect to and the remote/local paths
hostname, remote_dirname, destdir = sys.argv[1:]

# load parameters to setup ssh connection
config = SSHConfig()
with open(os.path.expanduser('~/.ssh/config')) as config_file:
    config.parse(config_file)
d = config.lookup(hostname)

# connect
with closing(SSHClient()) as ssh:
    ssh.load_system_host_keys() #NOTE: no AutoAddPolicy() 
    ssh.connect(d['hostname'], username=d.get('user'))
    with closing(ssh.open_sftp()) as sftp:
        # cd into remote directory
        sftp.chdir(remote_dirname)
        # cd to local destination directory
        os.chdir(destdir)
        # download all files in it to destdir directory
        for filename in sftp.listdir():
            sftp.get(filename, filename)
