paramiko sftp python

我能够使用以下代码成功地与服务器建立连接。

import paramiko

key_file_test = './path_to_key_file/key_file.pub'

DOWNLOAD_UAT = {
    "USERNAME": "xxxxxxxx",
    "PASSWORD": "xxxxxxxx"
}

UAT_FTP_SITE = 'sftp-test.site.com'

transport = paramiko.Transport((UAT_SFTP_SITE,22))
transport.connect(username=DOWNLOAD_UAT['USERNAME'], password=DOWNLOAD_UAT['PASSWORD'])
transport.add_server_key(key)
sftp = paramiko.SFTPClient.from_transport(transport)

print(sftp.listdir())
''' ['archiv'] '''

sftp.put('test_sftp_upload_file.txt', remotepath='./')

然而,当我运行上面的最后一行时,我得到了以下错误输出。

根据文档,您应该指定完整的远程文件路径。

    :param str remotepath: the destination path on the SFTP server. Note
        that the filename should be included. Only specifying a directory
        may result in an error.

sftp.put(local_full_path_and_name, "/{f}".format(f=destination_filename))
