1. Requests库简介Requests库以其简洁的API,使得处理各种HTTP请求变得直观。它的Response对象包含了丰富的信息,如:content:响应内容的字节形式 cookies:服务器返回的Cookie集合 encoding:用于解码的编码 headers:响应头的不区分大小写字典 history:请求历史,包含重定向响应 status_code:HTTP状态代码,如...

· raise_for_status (布尔类型) – 每完成一个响应就自动调用 ClientResponse.raise_for_status(), 默认是False. 新增于2.0版本。 · read_timeout (浮点数) – 请求操作的超时时间。read_timeout是累计自所有的请求操作(请求,重定向,响应,数据处理)。默认情况下是 5*60秒(5分钟)。传递None或0来禁用超时...
