Return False return True print is_downloadable( '') Return False if 'html' in content_type.lower(): H = requests.head(url, allow_redirects= True)Ĭontent_type = header.get( 'content-type') import requestsĭoes the url contain a downloadable resource

This allows us to skip downloading files which weren't meant to be downloaded. That way involved just fetching the headers of a url before actually downloading it. I looked into the requests documentation and found a better way to do it. So if the file is large, this will do nothing but waste bandwidth. It works but is not the optimum way to do so as it involves downloading the file for checking the header. Headers usually contain a Content-Type parameter which tells us about the type of data the url is linking to.Ī naive way to do it will be - r = requests.get(url, allow_redirects= True) To solve this, what I did was inspecting the headers of the URL. When the URL linked to a webpage rather than a binary, I had to not download that file and just keep the link as is. This was one of the problems I faced in the Import module of Open Event where I had to download media from certain links. If you said that a HTML page will be downloaded, you are spot on.
