I will be using the god-send library requests for it. I will write about methods to correctly download binaries from URLs and set their filenames. What do you think will happen if the above code is used to download it? If you said that a HTML page will be downloaded, you are spot on.
This was one of the problems I faced in the Import module of Open Event where I had to download media from certain links. 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. To solve this, what I did was inspecting the headers of the URL. Headers usually contain a Content-Type parameter which tells us about the type of data the url is linking to.
A naive way to do it will be. It works but is not the optimum way to do so as it involves downloading the file for checking the header. So if the file is large, this will do nothing but waste bandwidth. I looked into the requests documentation and found a better way to do it. That way involved just fetching the headers of a url before actually downloading it. This allows us to skip downloading files which python download file from url meant to be downloaded.
To restrict download by file size, we can get the filesize from the Content-Length header and then do suitable comparisons. We can parse the url to get the filename. This will be give the filename in some cases correctly. However, there are times when python download file from url filename information is not present in the url.
In that case, python download file from url, the Content-Disposition header will contain the filename information. Here is how to fetch it. The url-parsing code in conjuction with the above method to get filename from Content-Disposition header will work for most of the cases. Use them and test the results. These are my 2 cents on downloading files using requests in Python.
