paramiko的sshclient与sftp

Question

如何通过远程服务器上的SSHClient使SFTP传输？我有一台本地主机和两台远程主机。远程主机是备份服务器和Web服务器。我需要在备份服务器上找到必要的备份文件，并通过sftp将其放到Web服务器上。我如何使paramiko的SFTP传输与paramiko的SSHClient一起工作？

Answer 1

paramiko.SFTPClient

例子：

import paramiko 
paramiko.util.log_to_file('/tmp/paramiko.log') 

# Open a transport 

host = "example.com" 
port = 22 
transport = paramiko.Transport((host, port)) 

# Auth 

password = "foo" 
username = "bar" 
transport.connect(username = username, password = password) 

# Go! 

sftp = paramiko.SFTPClient.from_transport(transport) 

# Download 

filepath = '/etc/passwd' 
localpath = '/home/remotepasswd' 
sftp.get(filepath, localpath) 

# Upload 

filepath = '/home/foo.jpg' 
localpath = '/home/pony.jpg' 
sftp.put(localpath, filepath) 

# Close 

sftp.close() 
transport.close()
