9 Requests HTTP Library
10 ~~~~~~~~~~~~~~~~~~~~~
11
12 Requests is an HTTP library, written in Python, for human beings.
13 Basic GET usage:
14
15 >>> import requests
16 >>> r = requests.get('https://www.python.org')
17 >>> r.status_code
18 200
19 >>> b'Python is a programming language' in r.content
20 True
21
22 ... or POST:
23
24 >>> payload = dict(key1='value1', key2='value2')
25 >>> r = requests.post('https://httpbin.org/post', data=payload)
26 >>> print(r.text)
27 {
28 ...
29 "form": {
30 "key1": "value1",
31 "key2": "value2"
32 },
33 ...
34 }
35
36 The other HTTP methods are supported - see `requests.api`. Full documentation
37 is at <https://requests.readthedocs.io>.
