APP提交POST请求，DATE中可变的数据怎么处理？

url1='https://njy.jsnjy.net.cn/web/user/checkPhone.action'

date1={
'phone':'15252221011',
'code':'386791',
'type':'1',
'deviceNum':'0806dad8-c96c-4619-aab4-1091c147a8fc',
'pAddress':'',
'pLat':'34.576264',
'label':'null',
'version':'3.2.2',
'userId':'',

'timestamp':'1634148969679',
'sign':'7e7f88bb0d06870367f685d19bfe4e65'
}
response=requests.post(url=url1,headers=headers,date=date1)

农技耘APP
提交的'timestamp':'1634148969679',
'sign':'7e7f88bb0d06870367f685d19bfe4e65' 这个数据怎末处理，每次提交抓包这两个值都会变

报错如下
Traceback (most recent call last):
File "F:\志愿者\农技耕耘\nongji.py", line 59, in
