なぜ再帰FTPはこのディレクトリで動作しませんか？

Question

Python newb ...注意！

いくつかのファイルを再帰的にftpしようとしています。以下のスクリプトでは、エラーが発生します。

Traceback (most recent call last):

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 

私はそれが何を意味するのか分かりません。しかし、ディレクトリを "/ path/dir2"に変更すると、 "file.txt"が出力されます。

/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 

マイスクリプト：ここ

は私のディレクトリ構造です

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

ftputil インポートでは、/ usr/local /ウェブに戻って指すsymblolicリンクに/ path/dir1のは/あり？

このエラーをステップオーバーする場合は、中のtry catchブロックを入れてログインでき...

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 

上記のすべてのエラーをキャッチします。あなたはまた、特定のエラーを取得してこれを取得することができます...

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
