Second, the property of the Response object
Third, abnormal Requests Library
supplement:
直接携带cookie请求url地址
1.cookie放在headers中
2.cookie字典传给cookies参数
cookie=”….”#通过字典推导式得到
cookie_dict={i.split(“=”)[0]: i.split(“=”)[1] for i in cookie.split(“;”)}
requests.get(url,headers=headers,cookies=cookie_dict)
先发送post请求，获取cookie,带上cookie请求登陆后的页面 —requests.session() 会话保持
1.实例化session
session=requests.session()#此时session实例同requests一样
2.session.post（url,data,headers）#服务器设置在本地的cookie会被保存在被session中
