from botbuilder.core import BotFrameworkAdapter, TurnContext
from botbuilder.schema import Activity, Attachment, HeroCard, CardImage, CardAction, ActionTypes

# 创建适配器
adapter = BotFrameworkAdapter()

# 创建carousel卡片
carousel_card = Attachment(
    content_type="application/vnd.microsoft.card.carousel",
    content={
        "type": "AdaptiveCard",
        "body": [
            {
                "type": "TextBlock",
                "text": "Item 1"
            },
            {
                "type": "TextBlock",
                "text": "Item 2"
            },
            {
                "type": "TextBlock",
                "text": "Item 3"
            }
