Python URL请求

Question

Let me start by saying I am extremely new to Python, but I am familiar with other programming languages. Before I dive into this project, I need to ask a few questions.

I need to be able to make URL GET, PUT, POST, and DELETE requests straight out of Python.

I'll be writing a library for specific use cases of those functions and I don't want users to have to go installing external libraries (like "Requests").

What is the best way to do this, urllib.request?

Thank you for educating me.

Since urllib.request.urlopen() is hard-wired to GET or POST, you will need http.client.HTTPConnection instead:

import http.client
import pprint

conn = http.client.HTTPConnection('www.jython.org')
c = conn.request('HEAD', '/index.html')
r = conn.getresponse()

pprint.pprint(r.getheaders())
print('Size of body:', len(r.read()))

The technique gets you "closer to the metal" and gives more control, but it loses all the comforts of urllib.request and its various highlevel services (like following redirects).
