当赠品结束时，如何对赠品的主持人进行DM

# 示例代码：检测赠品是否结束并准备通知
import datetime

def check_gift_ending(gift_info):
    current_time = datetime.datetime.now()
    if current_time >= gift_info['end_date']:
        return True
    return False

# 示例代码：从数据库获取主持人信息
def get_host_info(gift_id):
    # 假设使用SQL查询获取主持人信息
    host_info = db.execute("SELECT * FROM hosts WHERE gift_id = ?", (gift_id,))
    return host_info

# 示例代码：发送DM通知给主持人
def send_dm_notification(host_info, message):
    for host in host_info:
        # 假设使用某个即时通讯API发送DM
        dm_api.send_message(host['user_id'], message)

def notify_host_on_gift_end(gift_id):
    if check_gift_ending(get_gift_info(gift_id)):
        host_info = get_host_info(gift_id)
        message = "您的赠品活动已结束，请及时处理后续事宜。"
        send_dm_notification(host_info, message)
