How to get pdf filename with Python requests?

Question

I'm using the Python requests lib to get a PDF file from the web. This works fine, but I now also want the original filename. If I go to a PDF file in Firefox and click download it already has a filename defined to save the pdf. How do I get this filename?

For example:

import requests r = requests.get('http://www.researchgate.net/profile/M_Gotic/publication/260197848_Mater_Sci_Eng_B47_%281997%29_33/links/0c9605301e48beda0f000000.pdf') print r.headers['content-type']  # prints 'application/pdf' 

I checked the r.headers for anything interesting, but there's no filename in there. I was actually hoping for something like r.filename..

Does anybody know how I can get the filename of a downloaded PDF file with requests library?

Answer 1

It is specified in an http header content-disposition. So to extract the name you would do:

import re d = r.headers['content-disposition'] fname = re.findall("filename=(.+)", d)[0] 

Name extracted from the string via regular expression (re module).

Answer 2

Building on some of the other answers, here's how I do it. If there isn't a Content-Disposition header, I parse it from the download URL:

import re import requests from requests.exceptions import RequestException   url = 'http://www.example.com/downloads/sample.pdf'  try:     with requests.get(url) as r:          fname = ''         if "Content-Disposition" in r.headers.keys():             fname = re.findall("filename=(.+)", r.headers["Content-Disposition"])[0]         else:             fname = url.split("/")[-1]          print(fname) except RequestException as e:     print(e) 

There are arguably better ways of parsing the URL string, but for simplicity I didn't want to involve any more libraries.
