http
--- HTTP 模块¶
源代码: Lib/http/__init__.py
http
是一个包,它收集了多个用于处理超文本传输协议的模块:
http.client
是一个低层级的 HTTP 协议客户端;对于高层级的 URL 访问请使用urllib.request
http.server
包含基于socketserver
的基本 HTTP 服务类http.cookies
包含一些有用来实现通过 cookies 进行状态管理的工具http.cookiejar
提供了 cookies 的持久化
The http
module also defines the following enums that help you work with http related code:
- class http.HTTPStatus¶
在 3.5 版本加入.
enum.IntEnum
的子类,它定义了组 HTTP 状态码,原理短语以及用英语书写的长描述文本。用法:
>>> from http import HTTPStatus >>> HTTPStatus.OK HTTPStatus.OK >>> HTTPStatus.OK == 200 True >>> HTTPStatus.OK.value 200 >>> HTTPStatus.OK.phrase 'OK' >>> HTTPStatus.OK.description 'Request fulfilled, document follows' >>> list(HTTPStatus) [HTTPStatus.CONTINUE, HTTPStatus.SWITCHING_PROTOCOLS, ...]

模块中,。 枚举名等于常量名 (例如 http.HTTPStatus.OK
也可以是 http.client.OK
)。
在 3.7 版本发生变更: 添加了 421 MISDIRECTED_REQUEST
