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>. | |
