1、Requests 请求常用
- url：请求的 url 地址，接口文档标注的接口请求地址。
- params：请求数据中的链接，常见的一个 get 请求，请求参数都是在 url 地址中。
- data：请求数据，参数表单的数据格式。
- json：接口常见的数据请求格式。
- headers：请求头信息，http 请求中，比如说编码方式等内容添加。
- cookie：保存的用户登录信息，比如做一些充值功能，但是需要用户已经登录，需要 cookie 信息的请求信息传输。
2、Requests 响应内容
- r.encoding：获取当前编码。
- r.encoding = 'utf-8'：设置编码
- r.text：以 encoding 解析返回内容。字符串方式的响应体会自动根据响应头部的字符编码进行解码。
- r.cookies：返回 cookie。
- r.headers：以字典对象存储服务器响应头，但是这个字典键名不区分大小写，若键不存在则返回 None。
- r.json()：requests 中内置的 json 解码器，以 json 形式返回。如果返回的内容不是 json 格式的，则解析时会出错。
- r.content：以字节形式返回。字节形式的响应体，会自动解码 gzip 和 deflate 压缩。
