date.future？有时是不正确的

import datetime

from tencentcloud.common.profile.client_profile import ClientProfile
from tencentcloud.common.profile.http_profile import HttpProfile

    # 创建云函数触发器
    cred = credential.Credential("your-secret-id", "your-secret-key")
    httpProfile = HttpProfile()
    httpProfile.endpoint = "scf.tencentcloudapi.com"
    clientProfile = ClientProfile()
    clientProfile.httpProfile = httpProfile
    client = scf_client.ScfClient(cred, "ap-guangzhou", clientProfile)
    
    # 触发云函数
    request = models.InvokeRequest()
    request.FunctionName = "your-function-name"

    request.Payload = '{"date": "' + future_date.strftime("%Y-%m-%d") + '"}'
    response = client.Invoke(request)
    
    return response
