爲什麼不會遞歸ftp在這個目錄下工作？

Question

Python newb ...小心！

我想遞歸地ftp一些文件。在下面的腳本中，出現錯誤：

Traceback (most recent call last): 
    File "dump.py", line 7, in <module> 
    for root,dirs,files in recursive:

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 

我不知道這意味着什麼。但是，當我將目錄更改爲「/ path/dir2」時，它將工作並打印出「file.txt」。

這裏是我的目錄結構：

/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 

我的腳本： 進口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

是否有/路徑symblolic鏈接/ DIR1 /回指向在/ usr /本地/網絡？

如果要執行這個錯誤，你可以把一個try catch塊和註銷...

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 

上面會捕獲所有的錯誤。你也可以導入你得到的具體錯誤，並做到這一點...

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
