记录一次群答问：requests获取cookie

问题： 

为了测试，写的sever，下面仅为set cookie的部分代码 

response = make_response('{"code":9420, "msg":"恭喜%s，登录成功","token":"%s"}'%(username, token))
            response.set_cookie(username,token)  # 设置cookie
            return response

测试 

import requests

data = {"username":"qzcsbj","password":"123456"}
url="http://127.0.0.1:9999/login"
r = requests.post(url,data)
print(r)
print(r.status_code)
print(r.text)
print(r.cookies)  # response.cookies返回的是RequestsCookieJar对象
print(requests.utils.dict_from_cookiejar(r.cookies))
print(requests.utils.dict_from_cookiejar(r.cookies)['qzcsbj'])

输出结果：　

<Response [200]>

200

{"code":9420, "msg":"恭喜qzcsbj，登录成功","token":"970aa0ddb521bcde8ce7f1592a889e1c"}

<RequestsCookieJar[<Cookie qzcsbj=970aa0ddb521bcde8ce7f1592a889e1c for 127.0.0.1/>]>

{'qzcsbj': '970aa0ddb521bcde8ce7f1592a889e1c'}

970aa0ddb521bcde8ce7f1592a889e1c

如果没有上面set cookie的代码，

print(r.cookies)的输出结果就是<RequestsCookieJar[]>
