pysftp Paramiko PasswordRequiredException:私钥文件已加密
提问于 2020-10-28 05:17:48
当使用以下代码连接到SFTP服务器时，我收到以下错误。
from base64 import decodebytes
import pysftp
from paramiko import RSAKey
host = 'where_it_should_be'
username = 'thename'
private_key = 'private_key'
keydata = "AAAAAB..."

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')错误：

问题是我没有指定ssh私钥密码。使用Pysftp，它可以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:
