使用以下代码连接到SFTP服务器时，出现以下错误。
from base64 import decodebytes
import pysftp
from paramiko import RSAKey
host = 'where_it_should_be'
username = 'thename'
private_key = 'private_key'
keydata = "AAAAAB..."
key = RSAKey(data=decodebytes(keydata))
cnopts = pysftp.CnOpts()
cnopts.hostkeys.add(host, 'ssh-rsa', key)
with pysftp.Connection(host, username, private_key, cnopts=cnopts) as server:
server.get('file_name.pdf')

最佳答案
问题是我没有指定ssh私钥密码短语。使用Pysftp可以将它作为另一个参数添加到Connection中。
from base64 import decodebytes
import pysftp
from paramiko import RSAKey
host = 'where_it_should_be'
username = 'thename'
private_key = 'private_key'
keydata = "AAAAAB..."
key = RSAKey(data=decodebytes(keydata))
cnopts = pysftp.CnOpts()
cnopts.hostkeys.add(host, 'ssh-rsa', key)
with pysftp.Connection(
host, username, private_key, private_key_pass='secret',cnopts=cnopts
) as server:
server.get('file_name.pdf')
