Size of raw response in bytes

Question

I need to make a HTTP request and determine the response size in bytes. I have always used request for simple HTTP requests, but I am wondering if I can achieve th

Answer 1

Just take the len() of the content of the response:

>>> response = requests.get('https://github.com/')
>>> len(response.content)
51671

If you want to keep the streaming, for instance if the content is (too) large you can iterate over chunks of the data and sum their sizes:

>>> with requests.get('https://github.com/', stream=True) as response:
...     size = sum(len(chunk) for chunk in response.iter_content(8196))
>>> size
51671

Answer 2

r.raw is an instance of urllib3.response.HTTPResponse. We can count the length of response by looking up the response's header Content-length or use built-in function len().
