该代码不起作用:
def sftp_connection(self):
import pysftp
connection = pysftp.Connection(self.host, username=self.system_name,
private_key=os.path.join(HOME, '.ssh', 'id_rsa'))
# in the next lines I try to use AutoAddPolicy
client = connection.sftp_client()
client.load_host_keys(os.path.expanduser('~/.ssh/known_hosts'))
client.set_missing_host_key_policy(paramiko.client.AutoAddPolicy)
return connection
这是异常(exception):

在尝试设置
host_key_policy
之前,我得到了异常(exception)。我找不到通过pysftp访问客户端实例的其他方法。
有没有办法在我收到异常之前设置
AutoAddPolicy
?有一个相关的question。我的问题是关于如何应用旧问题中提供的几种解决方案之一。
最佳答案
pysftp根本不使用Paramiko SSHClient
class,它使用了更底层的 Transport
class。因此它不具有MissingHostKeyPolicy
的 SSHClient
功能。
您将必须自己实现。
一种可能的实现方式可以是:
host = 'example.com'
# Loads .ssh/known_hosts
cnopts = CnOpts()
hostkeys = None
if cnopts.hostkeys.lookup(host) == None:
print("New host - will accept any host key")
# Backup loaded .ssh/known_hosts file
hostkeys = cnopts.hostkeys
# And do not verify host key of the new host
cnopts.hostkeys = None
with Connection(host, username=user, private_key=pkey, cnopts=cnopts) as sftp:
if hostkeys != None:
print("Connected to new host, caching its hostkey")
hostkeys.add(host, sftp.remote_server_key.get_name(), sftp.remote_server_key)
hostkeys.save(pysftp.helpers.known_hosts())
关于python - 将Paramiko AutoAddPolicy与pysftp一起使用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/53666106/
