http — HTTP 模块 ¶

源代码： Lib/http/__init__.py

http 是集合了几个操控 HTTP (超文本传输协议) 模块的包：

• http.client 是低级 HTTP 协议客户端；对于高级 URL 打开使用 urllib.request

• http.server 包含基本 HTTP 服务器类基于 socketserver

• http.cookies 是拥有管理 Cookie 实现状态的实用工具

• http.cookiejar 提供 Cookie 的持久性

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

class http. HTTPStatus ¶

3.5 版新增。

子类化的 enum.IntEnum that defines a set of HTTP status codes, reason phrases and long descriptions written in English.

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>, ...]
			
						

HTTP 状态码 ¶

支持， IANA-registered 状态码可用于 http.HTTPStatus 是：

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 ).

3.7 版改变： 添加 421 MISDIRECTED_REQUEST 状态码。

3.8 版新增： 添加 451 UNAVAILABLE_FOR_LEGAL_REASONS 状态码。
