如何使用 Python SFTP/Paramiko 将 zip 文件从一台服务器传输到另一台服务器

Question

我正在尝试使用 Python 脚本在两台服务器之间进行 SFTP。起初，我尝试将文件下载到本地计算机，但由于权限错误而失败，不知道为什么限制将文件复制到本地文件夹。

任何想法都会受到赞赏。下面是代码sn-p（只完成了一半）

import paramiko

host= <defined here>
user = <defined here>
pswd = <defined here>

ssh = paramiko.SSHClient()
# automatically add keys without requiring human intervention
ssh.set_missing_host_key_policy( paramiko.AutoAddPolicy() )
ssh.connect(host, username=user, password=pswd)
ftp = ssh.open_sftp()

ftp.get(source_path,destination_path)

ftp.close()

这能解决问题吗？

import paramiko

from_host = <defined here>
from_user = <defined here>
from_pass = <defined here>

to_host = <defined here>
to_user = <defined here>
to_pass = <defined here>

from_client = paramiko.SSHClient()
# automatically add keys without requiring human intervention
from_client.set_missing_host_key_policy( paramiko.AutoAddPolicy() )
from_client.connect(from_host, username=from_user, password=from_password)

to_client = paramiko.SSHClient()
# automatically add keys without requiring human intervention
to_client.set_missing_host_key_policy( paramiko.AutoAddPolicy() )
to_client.connect(to_host, username=to_user, password=to_password)

# Open an sftp client for both servers
from_ftp = from_client.open_sftp()
to_ftp = to_client.open_sftp()

# Open the file on the from server. Returns a file like object
with from_ftp.open(source_path) as f:
    # putfo takes an open file object and creates it at the specifies path
    to_ftp.putfo(f, path_where_you_want_the_file_on_to_server)  # need filename

from_ftp.close()
to_ftp.close()
