我正在尝试在 NodeJS 上使用 AdaptiveCards npm 包以编程方式生成卡片，但我看不到如何生成 JSON 以传递给消息。到目前为止，我的代码相当简单：

session.send(new builder.Message(session).addAttachment({
    contentType: "application/vnd.microsoft.card.adaptive",
    content: createCard()
})); 

function createCard() {
    let card = new adaptiveCards.AdaptiveCard({ type: "AdaptiveCard" });

    // add a text block
    card.addItem(new adaptiveCards.TextBlock({
        text: 'Issue #1',
        weight: "bolder",
        size: "medium"
    }));

    return card;
}

我试图调用render方法，但它不起作用。我也尝试打电话JSON.stringify(card)，但我收到TypeError: Converting circular structure to JSON消息错误。任何想法？如果我将 JSON 传递给内容附件，一切正常。

要使用适用于 Node.js 的 Bot Framework SDK 发送自适应卡片，请使用Adaptivecards.io中描述的 JSON 格式，然后将自适应卡片对象作为附件添加到botbuilder.Message对象，然后照常发送消息。

例子：

// adaptive cards example from:
// https://docs.microsoft.com/en-us/bot-framework/nodejs/bot-builder-nodejs-send-rich-cards
bot.dialog('adaptive_card_demo', function(session) {
    var adaptiveCardMessage = new builder.Message(session)
    .addAttachment({
        contentType: "application/vnd.microsoft.card.adaptive",
        content: {
            type: "AdaptiveCard",
            speak: "<s>Your  meeting about \"Adaptive Card design session\"<break strength='weak'/> is starting at 12:30pm</s><s>Do you want to snooze <break strength='weak'/> or do you want to send a late notification to the attendees?</s>",
               body: [
                    {
                        "type": "TextBlock",
                        "text": "Adaptive Card design session",
                        "size": "large",
                        "weight": "bolder"
                    },
                    {
                        "type": "TextBlock",
                        "text": "Conf Room 112/3377 (10)"
                    },
                    {
                        "type": "TextBlock",
                        "text": "12:30 PM - 1:30 PM"
                    },
                    {
                        "type": "TextBlock",
                        "text": "Snooze for"
                    },

                                "isSelected": true

                                "value": "15"
                            },
                            {
                                "title": "30 minutes",
                                "value": "30"
                            }
                        ]
                    }
                ],
                "actions": [
                    {
                        "type": "Action.Http",

                        "title": "Snooze"
                    },
                    {
                        "type": "Action.Http",
                        "method": "POST",
                        "url": "http://foo.com",
                        "title": "I'll be late"
                    },
                    {
                        "type": "Action.Http",
                        "method": "POST",
                        "url": "http://foo.com",
                        "title": "Dismiss"
                    }
                ]
        }
    });

    session.send(adaptiveCardMessage);
    session.endDialog();
});
