21.11. http — HTTP modules - Python 3.5.9 documentation 编辑

Source code: Lib/http/__init__.py

http is a package that collects several modules for working with the HyperText Transfer Protocol:

• http.client is a low-level HTTP protocol client; for high-level URL opening use urllib.request
• http.server contains basic HTTP server classes based on socketserver
• http.cookies has utilities for implementing state management with cookies
• http.cookiejar provides persistence of cookies

http is also a module that defines a number of HTTP status codes and associated messages through the http.HTTPStatus enum:

class http.HTTPStatus

New in version 3.5.

A subclass of 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>, ...]

21.11.1. HTTP status codes

Supported, IANA-registered status codes available in http.HTTPStatus are:

In order to preserve backwards compatibility, enum values are also present in the 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).
