I will write about methods to correctly download binaries from URLs and set their filenames. Requests is a versatile HTTP library in python with various applications. What is GZIP?

So if you are not enabling GZIP in the request options then the actual response from the server that you will get is compressed gibberish that will result in a corrupt file. Also make sure the headers that you are setting are correct and they are in sync with what a normal request to that file would look like. Now, inspect that request and check what are the actual Request Headers of the request and make sure they are in sync with your headers from your code.

This denotes how big of a chunk should be read at a time, which may increase or decrease the speed of the download.
