Python pysftp put_r does not work on Windows

问题

I'd like to upload multiple files from a Windows directory to an SFTP server using pysftp 0.2.8. I've read up the doc and it suggests to use put_d or put_r but both give me the following error:

OSError: Invalid path:

sftp_local_path = r'C:\Users\Swiss\some\path'

sftp_remote_path = '/FTP/LPS Data/ATC/RAND/20191019_RAND/XML'

with pysftp.Connection("xxx.xxx.xxx.xxx", username=myUsername, password=myPassword) as sftp:
    with sftp.cd(sftp_remote_path):
        sftp.put_r(sftp_local_path, sftp_remote_path)
        for i in sftp.listdir():
            lstatout=str(sftp.lstat(i)).split()[0]
            if 'd' in lstatout: print (i, 'is a directory')

sftp.close()

I'd like to be able to copy all files or selected files from my local directory to the SFTP server.

I cannot reproduce your exact problem, but indeed the recursive functions of pysftp are known to be implemented in a way that makes them fail on Windows (or any system that does not use *nix-like path syntax).

It uses os.sep and os.path functions for remote SFTP paths, what is wrong, as SFTP paths always use a forward slash.

But you can easily implement a portable replacement:

import os

def put_r_portable(sftp, localdir, remotedir, preserve_mtime=False):
    for entry in os.listdir(localdir):
        remotepath = remotedir + "/" + entry
        localpath = os.path.join(localdir, entry)
        if not os.path.isfile(localpath):
            try:
                sftp.mkdir(remotepath)
            except OSError:     
                pass
            put_r_portable(sftp, localpath, remotepath, preserve_mtime)
        else:
            sftp.put(localpath, remotepath, preserve_mtime=preserve_mtime)

Use it like:

put_r_portable(sftp, sftp_local_path, sftp_remote_path, preserve_mtime=False)
