一.概述 1.1 关于JSON数据格式 JSON (JavaScript Object Notation), specified by RFC 7159 (which obsoletes RFC 4627) and by ECMA-404, is a lightweight data interchange format inspired by JavaScript object literal syntax (although it is not a strict subset of Java…

官方文档:https://docs.python.org/3.5/library/http.html 偷个懒,截图如下: 即,http客户端编程一般用urllib.request库(主要用于“在这复杂的世界里打开各种url”,包括:authentication.redirections.cookies and more.). 1. urllib.request—— Extensible library for opening URLs 使用手册,结合代码写的很详细:HOW TO Fetch In…

http.server是用来构建HTTP服务器(web服务器)的模块,定义了许多相关的类. 创建及运行服务器的代码一般为: def run(server_class=HTTPServer, handler_class=BaseHTTPRequestHandler): server_address = ('', 8000) httpd = server_class(server_address, handler_class) httpd.serve_forever() 类HTTPServer,是T…

http.cookies — HTTP state management http.cookies模块定义了一系列类来抽象cookies这个概念,一个HTTP状态管理机制.该模块支持string-only的简单cookies,也支持任意序列化数据类型(serializable data-type)作为cookie的value. 该模块允许下列字符集都可以作为有效字符来表示Cookie name(as key):字符集,string.ascii_letters, string.digits and…
