Python is used very frequently to access resources on the internet.

Use the pycurl Module to Download Files in Python.

Use the urllib Module to Download Files in Python.

The above url-parsing code in conjunction with above program will give you filename from Content-Disposition header most of the time.Created: July-02, 2021 | Updated: October-12, 2021 import requestsįilename = getFilename_fromCd(r.headers.get('content-disposition')) In such a case, we need to get the Content-Disposition header, which contains the filename information. However, there are many cases where filename information is not present in the url for example –. url= ""Ībove will give the filename of the url. Below is a sample routine which fetches the last string after backslash(/).

To get the filename, we can parse the url. If contentLength and contentLength > 2e8: # 200 mb approx contentLength = header.get('content-length', None) To restrict the download by file size, we can get the filezie from the content-length header and then do as per our requirement. This allows us to skip downloading files which weren’t meant to be downloaded. However, there is a smarter way, which involved just fetching the headers of a url before actually downloading it. So let’s first get the type of data the url is linking to− > r = requests.get(url, allow_redirects=True) We can see the file is downloaded(icon) in our current working directory.īut we may need to download different kind of files like image, text, video etc from the web.

Open('facebook.ico', 'wb').write(r.content) Result R = requests.get(url, allow_redirects=True) open('facebook.ico', 'wb').write(r.content) R = requests.get(url, allow_redirects=True) 3. Let’s start a look at step by step procedure to download files using URLs using request library− 1. I am going to use the request library of python to efficiently download files from the URLs. Python provides different modules like urllib, requests etc to download files from the web.
