--------------
|
|
|
|
:mod:`http` is a package that collects several modules for working with the
|
|
HyperText Transfer Protocol:
|
|
|
|
* :mod:`http.client` is a low-level HTTP protocol client; for high-level URL
|
|
opening use :mod:`urllib.request`
|
|
* :mod:`http.server` contains basic HTTP server classes based on :mod:`socketserver`
|
|
* :mod:`http.cookies` has utilities for implementing state management with cookies
|
|
* :mod:`http.cookiejar` provides persistence of cookies
|
|
|
|
:mod:`http` is also a module that defines a number of HTTP status codes and
|
|
associated messages through the :class:`http.HTTPStatus` enum:
|
|
|
|
.. class:: HTTPStatus
|
|
|
|
.. versionadded:: 3.5
|
|
|
|
A subclass of :class:`enum.IntEnum` that defines a set of HTTP status codes,
|
|
reason phrases and long descriptions written in English.
|
|
|
|
Usage::
|
|
|
|
>>> from http import HTTPStatus
|
|
>>> HTTPStatus.OK
|
|
<HTTPStatus.OK: 200>
|
|
>>> HTTPStatus.OK == 200
|
|
True
|
|
>>> http.HTTPStatus.OK.value
|
|
200
|
|
>>> HTTPStatus.OK.phrase
|
|
'OK'
|
|
>>> HTTPStatus.OK.description
|
|
'Request fulfilled, document follows'
|
|
>>> list(HTTPStatus)
|
|
[<HTTPStatus.CONTINUE: 100>, <HTTPStatus.SWITCHING_PROTOCOLS: 101>, ...]

In order to preserve backwards compatibility, enum values are also present
|
|
in the :mod:`http.client` module in the form of constants. The enum name is
|
|
equal to the constant name (i.e. ``http.HTTPStatus.OK`` is also available as
|
|
``http.client.OK``).
|
|
|
|
.. versionchanged:: 3.7
|
|
Added ``421 MISDIRECTED_REQUEST`` status code.
