怎么给payload里面的内容，拍卖&开始时间换成minue

import datetime

#//获取当前时间以后的多少分钟的时间
m = 4
date = ((datetime.datetime.now()+datetime.timedelta(minutes=m)).strftime("%Y-%m-%d %H:%M:%S"))
# print date
minue = date
print(minue)
 
payload={"name":"拍卖",
         "logo":"",
         "activeStart":"开始时间",
         "activeEnd":"",
         "countDownTime":60,
         "failCountDownTime":60,
         "marketId":70,
         "type":"NORMAL",
         "vehicleState":"USED",
         "active":"true",
         "customBid":"false"}
