Python newb ...小心！

我试图递归ftp一些文件。在下面的脚本中，我收到一个错误：

Traceback (most recent call last):
  File "dump.py", line 7, in <module>
    for root,dirs,files in recursive:
  File "/usr/local/lib/python2.6/site-packages/ftputil/ftputil.py", line 880, in walk

ftputil.ftp_error.PermanentError: 550 /usr/local/web: No such file or directory
Debugging info: ftputil 2.6, Python 2.6.5 (linux2)

Exited: 256

我不知道这意味着什么。但是，当我将目录更改为“/ path / dir2”时，它工作并打印出“file.txt”。

这是我的目录结构：

/path/dir1/another/file.txt # I get the above error with this path
/path/dir2/another/file.txt # this works fine, even though the directories have the same structure

我的剧本： import ftputil

ftp = ftputil.FTPHost('ftp.site.com','user','pass')
recursive = ftp.walk("/path/dir1",topdown=True,onerror=None)
for root,dirs,files in recursive:
 for name in files:
  print name
ftp.close

/ path / dir1 /中是否存在指向/ usr / local / web的符号链接？

如果您想要跳过此错误，可以在其中输入try catch块并记录...

ftp = ftputil.FTPHost('ftp.site.com','user','pass')
try:
    recursive = ftp.walk("/path/dir1",topdown=True,onerror=None)
    for root,dirs,files in recursive:
         for name in files:
               print name
except Error e:
   print "Error: %s occurred" % (e)
ftp.close

以上将捕获所有错误。你也可以导入你得到的特定错误并执行此操作...

import ftputil.ftp_error.PermanentError as PermanentError
ftp = ftputil.FTPHost('ftp.site.com','user','pass')
try:
    recursive = ftp.walk("/path/dir1",topdown=True,onerror=None)
    for root,dirs,files in recursive:
         for name in files:
              print name
except PermanentError e:
   print "Permanent Error: %s occurred" % (e)
ftp.close

为什么递归ftp不会在这个目录中工作？
