Requests HTTP Library
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Requests is an HTTP library, written in Python, for human beings. Basic GET
|
|
usage:
|
|
|
|
>>> import requests
|
|
>>> r = requests.get('https://www.python.org')
|
|
>>> r.status_code
|
|
200
|
|
>>> 'Python is a programming language' in r.content
|
|
True
|
|
|
|
... or POST:
|
|
|
|
>>> payload = dict(key1='value1', key2='value2')
|
|
>>> r = requests.post('https://httpbin.org/post', data=payload)
|
|
>>> print(r.text)
|
|
{
|
|
...
|
|
"form": {
|
|
"key2": "value2",
|
|
"key1": "value1"
|
|
},
|
|
...
|
|
}
|
|
|
|
The other HTTP methods are supported - see `requests.api`. Full documentation
|
|
is at <http://python-requests.org>.
