用session维持会话

import requests
'''
下面的data是先在浏览器中登录，然后打开开发者选项，找到一个请求方法为POST的请求，复制里面的Form Data
'''
url = '......'
data = {
        username:'......',
        password:flz_sanqianchi,
        rememberMe:true,
        lt:LT-82465-9HtQnC7ZASZHohtnQlrqMvXo7cI2B7,
        execution:e1s1,
        }
headers = {'user-agent':'Mozolla/5.0'}
'''
这里用requests的session来请求网页，做到维持同一会话的目的
'''
session = requests.Session()
reqsonse = session.post(url=url, headers=headers, data=data)
'''
接下来就可以请求别的登陆后的页面，而不需要处理cookies
'''
url2 = '这里是已经登录后的某一页面'
response = session.get(url=url2, headers=headers)
