http --- HTTP 模塊?

源代碼: Lib/http/__init__.py

http 是一個包，它收集了多個用于處理超文本傳輸協(xié)議的模塊:

http 也是一個通過 http.HTTPStatus 枚舉定義了一些 HTTP 狀態(tài)碼以及相關(guān)聯(lián)消息的模塊

class http.HTTPStatus?

3.5 新版功能.

enum.IntEnum 的子類，它定義了組 HTTP 狀態(tài)碼，原理短語以及用英語書寫的長描述文本。

用法:

>>> from http import HTTPStatus
>>> HTTPStatus.OK
<HTTPStatus.OK: 200>
>>> HTTPStatus.OK == 200
True
>>> HTTPStatus.OK.value
200
>>> HTTPStatus.OK.phrase
'OK'
>>> HTTPStatus.OK.description
'Request fulfilled, document follows'
>>> list(HTTPStatus)
[<HTTPStatus.CONTINUE: 100>, <HTTPStatus.SWITCHING_PROTOCOLS: 101>, ...]
