用pysftp连接FTP服务器

Question

HOST_LIST = [["10.10.10.04", "user", "pasword"]] #ftp4

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

 def get_r_portable(self, sftp, remotedir, localdir, preserve_mtime=False):
    for entry in sftp.listdir(remotedir):
        remotepath = remotedir + "/" + entry

                    sftp.get(remotepath, localpath, preserve_mtime=preserve_mtime)


for host in self.HOST_LIST:

您正在连接到Filezilla中的FTP服务器。

pysftp是SFTP库。

FTP和SFTP是完全不同的协议。

要在Python中与FTP连接，请使用ftplib。
