How to get the file name from a link before downloading the file?

Question

For example I have a link and I want to know the file name before I start the download.

There are many questions like this, but they all boil down to extracting the file name from the link. What should I do when file name is not in the link?

I found this solution, but it is not working in my situation. I keep get the same link I passed to urlopen() instead of the direct link to the file.

Answer 1

For your example, you can use the following:

>>> from urllib.request import urlopen
>>> url = 'http://booksdl.org/get.php?md5=5c9afff27ee041c34c698d62bd510616&key=D3JE34WPUY7LQ11U'
>>> response = urlopen(url)
>>> response.headers.get_filename()
