Establishing the name associated with a HTML link

I wish to download the files associated with a set of links in a html document.

A link might appear like this:

<a href="d?kjdfer87">

But when I click on it in my browser, I get the following file downloaded:

file2.txt

The following will download the file via python:

opener = urllib.request.build_opener()
r = opener.open("unknown.txt")
r.read()

but how do I establish that the file was actually called file2.txt?

It's actually this simple:

r.info().get_filename()

The Content-Disposition header in the HTTP response is what specified that the response should be downloaded with a specific filename.

See: How to encode the filename parameter of Content-Disposition header in HTTP?

Check the Content-Disposition header on the response. It can suggest a filename. I believe this would be in r.info().dict['Content-Disposition'].

I'm not sure why you think you need the name. You should call it in exactly the same way as the browser does, ie with the value in the href.
