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
|
||||
>>> b'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": {
|
||||
"key1": "value1",
|
||||
"key2": "value2"
|
||||
},
|
||||
...
|
||||
}
|
||||
|
||||
The other HTTP methods are supported - see `requests.api`. Full documentation
|
||||
is at <https://requests.readthedocs.io>.

``MutableMapping`` as well as dict's ``copy``. Also
|
||||
provides ``lower_items``.
|
||||
|
||||
All keys are expected to be strings. The structure remembers the
|
||||
case of the last key to be set, and ``iter(instance)``,
|
||||
``keys()``, ``items()``, ``iterkeys()``, and ``iteritems()``
|
||||
will contain case-sensitive keys. However, querying and contains
|
||||
testing is case insensitive::
|
||||
|
||||
cid = CaseInsensitiveDict()
|
||||
cid['Accept'] = 'application/json'
|
||||
cid['aCCEPT'] == 'application/json' # True
|
||||
list(cid) == ['Accept'] # True
|
||||
|
||||
For example, ``headers['content-encoding']`` will return the
|
||||
value of a ``'Content-Encoding'`` response header, regardless
|
||||
of how the header name was originally stored.
|
||||
|
||||
If the constructor, ``.update``, or equality comparison
|
||||
operations are given keys that have equal ``.lower()``s, the
|
||||
behavior is undefined.
