Question

我们可以使用ftplib在Python中提供完整的FTP支持。我试图通过递归传递根目录名来从几个根目录下载所有文件

import sys
import ftplib
import os
from ftplib import FTP

try:
  ftp=FTP("ftpservice.example.com","username","password")
except EOFError as e:
  raise Exception('Disconnection event...!!!')

def downloadFiles(path,destination):

  dest_path = ""
  try:
    ftp.cwd(path)
    os.chdir(destination)
    dest_path = destination[0:len(destination)-1]+path
    os.mkdir(dest_path)
  except OSError:
    print "%s alredy exist"%path
  except ftplib.error_perm:
    raise Exception("error: Invalid entry- could not change to ",path)

  filelist=ftp.nlst()

  for file in filelist:
    try:
        ftp.cwd(path+file+"/")
        downloadFiles(path+file+"/",destination)
    except ftplib.error_perm:
        os.chdir(destination[0:len(destination)-1]+path)
        ftp.retrbinary("RETR "+file, open(os.path.join(dest_path,file),"wb").write)
        print file + " downloaded"
  return

if __name__ == '__main__':

  sources = ["ab","aldf","amrdf","lient","BF"] #root folder of the file tree
  dest="/home/name/ftp_data/"  # place to which the files are download

  for source in sources:
    source = "/%s/"%source
    downloadFiles(source,dest)
  print "\nDownload Completed... !!!"

程序执行并下载了很多文件，但在下载之间显示

ftplib.error_perm: 550 companymaster.ace: The system cannot find the file specified.

为什么会这样呢？

实际上我的程序列出了目录下的所有项目，如果该项目不是目录，则下载每个项目。

但我得到“系统找不到指定的文件”。我真的很困惑。

任何帮助？

使用python ftplib显示系统下载文件无法找到指定的文件
