Paramiko TypeError: '<' not supported between instances of 'int' and 'str'

Question

我目前正在尝试使用 Python 中 Lambda 函数中的 Paramiko 库将文件从 SFTP 移动到 S3 存储桶。但是面临类型错误。

我的代码：

def open_ftp_connection(ftp_host, ftp_port, ftp_username, ftp_password):
    '''
    Opens ftp connection and returns connection object
    '''
    client = paramiko.SSHClient()
    client.load_system_host_keys()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

    try:
        transport = paramiko.Transport(ftp_host, ftp_port)
    except Exception as e:
        return 'conn_error'
    try:
        transport.connect(username=ftp_username, password=ftp_password)
    except Exception as identifier:
        return 'auth_error'

    ftp_connection = paramiko.SFTPClient.from_transport(transport)

    return ftp_connection

ftp_host 是 str - 13.xxx.1xx.xx
ftp_port 是 str - 22
ftp_username 是 str

错误：

[ERROR] TypeError: '<' not supported between instances of 'int' and 'str'
Traceback (most recent call last):
  File "/var/task/transfer_data.py", line 159, in transfer_handler
    ftp_connection = paramiko.SFTPClient.from_transport(transport)

    return clamp_value(MIN_WINDOW_SIZE, window_size, MAX_WINDOW_SIZE)

    return max(minimum, min(val, maximum))

正如@Vishnudev 回答的那样。

端口应以整数形式给出。

Paramiko TypeError: '<' not supported between instances of 'int' and 'str'

Paramiko TypeError: '<' not supported between instances of 'int' and 'str'

python

ssh

sftp
