7 Requests HTTP Library
8 ~~~~~~~~~~~~~~~~~~~~~
9
10 Requests is an HTTP library, written in Python, for human beings.
11 Basic GET usage:
12
13 >>> import requests
14 >>> r = requests.get('https://www.python.org')
15 >>> r.status_code
16 200
17 >>> b'Python is a programming language' in r.content
18 True
19
20 ... or POST:
21
22 >>> payload = dict(key1='value1', key2='value2')
23 >>> r = requests.post('https://httpbin.org/post', data=payload)
24 >>> print(r.text)
25 {
26 ...
27 "form": {
28 "key1": "value1",
29 "key2": "value2"
30 },
31 ...
32 }
33
34 The other HTTP methods are supported - see `requests.api`. Full documentation
35 is at <https://requests.readthedocs.io>.
