return response.json()

bot = Binance(
API_KEY='',
API_SECRET=''
)
account=bot.futuresAccount()
cl=bot.ChangeLeverage(symbol='BTCUSDT',leverage=2)

当我在数据中发送时间戳时，我会收到以下错误：{"代码"：-1102，"消息"："强制参数'timestamp'未发送、为空/null或格式错误。"}。futuresAccount((运行良好，但ChangeLeverage((不行。我不知道如何解决这个问题。

Answer 1

time.time((将从epoch开始给您秒，Binance预计为毫秒。

所以一般来说，它应该是int(time.time((*1000(的形式
