Stop a file download in Python Requests

Question

So far I'm seeing a lot of info on how to download a file with the Requests module, but nothing covering actually cancelling a download.

I'm currently looping through a series of URLs to see if I get a 200 response code or not. If I land on a URL that starts a file download ( r.status_code == 200 ), how do I cancel this file download, or better yet: Preventing downloading in the first place?

代替GET，您可以使用HEAD请求仅获取标头信息。

r = requests.head('http://www.example.com')
