一. 为请求添加cookies
在上一篇文章中，可以看出，如果不给request请求加上cookie，当我们获取登录后的页面的考勤信息时，会自动跳转到登录页面。由于http是无状态协议，cookie的作用就是跟踪会话
注意cookies也要按照**kwargs传参的方式，即以key=value的形式传入，其中value是字典形式，这和params比较类似
import requests #调用登录接口——生成cookies #从响应的消息头中，获取身份令牌 url = "https://www.ketangpai.com/SummaryApi/attence?courseid=MDAwMDAwMDAwMLOGy9yHz7ev" params = {"courseid": "MDAwMDAwMDAwMLOGy9yHz7ev"} cookies = {"ketangpai_home_remember": "think%3A%7B%22username%16293798223OGpZaIudFqhc6Gl7LQetmZtmfOk2RhbQ%292038012%22expire%22%3A%22MDAwMDAwMDAwMLOGud6Gub9phd523rG2dZ4%22%2C%22token%22%3A%22MDAwMDAwMDAwMMurrpWavLehhs1-3LLfgduEt4OWepuomcWmmqaMiHtnr5ylzYWosKKZq6HQxtOK0ZCme5p-q6iZu2yrn4uNhJ3KedDYk7ivboS4it6xuZGShN1z3n6KYW0%22%7D"} res = requests.request("get", url, params=params, cookies=cookies) print(res.status_code) print(res.text.encode('latin-1').decode('unicode_escape'))

二. 从响应结果中获取cookies
此外，还可以通过响应结果来获取cookies
import requests url = "https://fanyi.baidu.com" res = requests.request("get", url) #res.cookies获得的是RequestCookieJar的实例 print(res.cookies) print(type(res.cookies)) #从响应结果当中获取cookies中键值对的值——参数为键名 print(res.cookies.get("BAIDUID"))
运行结果
<RequestsCookieJar[<Cookie BAIDUID=BEE625F269183991307D1097F72E:FG=1 for .baidu.com/>, <Cookie locale=zh for .baidu.com/>]> <class 'requests.cookies.RequestsCookieJar'>
