使用pysftp的sftp问题

Question

我正在尝试使用pysftp从本地机器发送一个文件到服务器。

当我使用命令行登录到服务器时：

sftp -o port=111 user_name@host

然后执行pwd，我得到/作为当前位置

因此，我想在pysftp中做同样的事情：

import pysftp
cnopts = pysftp.CnOpts()
cnopts.hostkeys = None

with pysftp.Connection("host", username="user_name", password="password", port=111, cnopts=cnopts) as sftp:
    print(sftp.pwd)
    sftp.put(local_file, sftp.pwd)

但是我得到了错误IOError: [Errno 13] Permission denied

不过，我可以在命令行和ftp客户机(如FileZilla )中使用相同的凭据进行sftp操作。

在这里，完整的错误跟踪：

Answer 1

通过在远程服务器上提供文件名解决了该问题。所以我就改变了

sftp.put(local_file, sftp.pwd)

至

sftp.put(local_file, "file_name.dat")
