我正在尝试使用python从sftp下载总文件夹文件

Question

这是我的代码

 import os
 import pysftp

 from stat import S_IMODE, S_ISDIR, S_ISREG
 cnopts = pysftp.CnOpts()
 cnopts.hostkeys = None  

 myHostname = "ftp.xyz.com"
 myUsername = "username"
 myPassword = "Password"

 with pysftp.Connection(host=myHostname, username=myUsername, password=myPassword, cnopts=cnopts) as 
 sftp:
print ("Connection succesfully stablished ... ")

def download_dir(remote_dir, local_dir, preserve_mtime=False):

    os.path.exists(local_dir) or os.makedirs(local_dir)
    dir_items = sftp.listdir_attr(remote_dir)
    for item in dir_items:
    # assuming the local system is Windows and the remote system is Linux
    # os.path.join won't help here, so construct remote_path manually
       remote_path = remote_dir + '/' + item.filename         
       local_path = os.path.join(local_dir, item.filename)
    if S_ISDIR(item.st_mode):
        download_dir(remote_path, local_path)
    else:
        sftp.get(remote_path, local_path, preserve_mtime=preserve_mtime)


download_dir("/home/ebsit11k/public_html/css/","E:/Naveen/Python/css/")

但是我只能将其中一个文件下载为随机文件。请任何人帮助我如何将文件夹中的全部文件下载到本地文件夹
