使用 pysftp 的 sftp 问题

Question

I'm trying to send a file from local machine to server thru sftp using pysftp

When I login to the server using command line as:

sftp -o port=111 user_name@host

then do pwd I get the / as the current location

So I want to do the same in pysftp as:

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)

but I get the error IOError: [Errno 13] Permission denied

Although, I'm able to sftp using the same credentials in command line and an ftp client like FileZilla

Here the full error trace:

Answer 1

The issue was resolved by providing the name of the file on the remote server. So I just changed

sftp.put(local_file, sftp.pwd)

to

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