python httplib/urllib get filename

is there a possibillity to get the filename 

e.g. xyz.com/blafoo/showall.html

if you work with urllib or httplib?

so that i can save the file under the filename on the server?

if you go to sites like 

xyz.com/blafoo/

you cant see the filename.

Thank you

Use urllib.request.Request:

import urllib

req = urllib.request.Request(url, method='HEAD')
r = urllib.request.urlopen(req)
print(r.info().get_filename())

Example :

In[1]: urllib.request.urlopen(urllib.request.Request('https://httpbin.org/response-headers?content-disposition=%20attachment%3Bfilename%3D%22example.csv%22', method='HEAD')).info().get_filename()
Out[1]: 'example.csv'

To get filename from response http headers:

import cgi

response = urllib2.urlopen(URL)
_, params = cgi.parse_header(response.headers.get('Content-Disposition', ''))
filename = params['filename']

To get filename from the URL: 

import posixpath
import urlparse 

path = urlparse.urlsplit(URL).path
filename = posixpath.basename(path)

I searched for you question on google and I saw that it was answered in stackoverflow before I believe.

Try looking at this post:

Using urllib2 in Python. How do I get the name of the file I am downloading?

The filename is usually included by the server through the content-disposition header:

content-disposition: attachment; filename=foo.pdf

You have access to the headers through 

result = urllib2.urlopen(...)
result.info() <- contains the headers


i>>> import urllib2
ur>>> result = urllib2.urlopen('http://zopyx.com')
>>> print result
<addinfourl at 4302289808 whose fp = <socket._fileobject object at 0x1006dd5d0>>
>>> result.info()
<httplib.HTTPMessage instance at 0x1006fbab8>
>>> result.info().headers
['Date: Mon, 04 Apr 2011 02:08:28 GMT\r\n', 'Server: Zope/(unreleased version, python 2.4.6, linux2) ZServer/1.1

Plone/3.3.4\r\n', 'Content-Length: 15321\r\n', 'Content-Type: text/html; charset=utf-8\r\n', 'Via: 1.1 www.zopyx.com\r\n', 'Cache-Control: max-age=3600\r\n', 'Expires: Mon, 04 Apr 2011 03:08:28 GMT\r\n', 'Connection: close\r\n']

Does not make much sense what you are asking. The only thing that you have is the URL. Either extract the last part from the URL or you may check the HTTP response for something like

content-disposition: attachment;filename="foo.bar"

This header can be set by the server to indicate that the filename is foo.bar. This is usually used for file downloads or something similar.
