使用Bot Framework SDK v4无法在MS Teams中呈现自适应卡

Question

我试图在MS Teams中呈现自适应卡，并收到消息“不支持指定的卡版本。” 我正在使用Bot Framework SDK v4-node.js

下面是代码段：在welcome.json中的自适应卡下面

{
"contentType": "application/vnd.microsoft.card.adaptive",
"content": {
    "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
    "type": "AdaptiveCard",
    "version": "1.0",
    "body": [
        {
           "type": "TextBlock",
           "text": "Default text input"
        }
    ],
    "actions": [
        {
           "type": "Action.Submit",
           "title": "OK"
        }
    ]
   }  
}

Node.js代码：

const { ActivityTypes, CardFactory } = require('botbuilder');
const WelcomeDialogCard = require('./Welcome.json');
let strJson = JSON.stringify(WelcomeDialogCard );
const cardJson = JSON.parse(strJson);
const confirmationCard = CardFactory.adaptiveCard(cardJson);
await turnContext.sendActivity({ attachments: [confirmationCard ] });

Answer 1

看来您的自适应卡格式不正确。类型，版本，主体和操作属性都应位于JSON对象的顶层。看下面的例子。

AdaptiveCard

{
    "contentType": "application/vnd.microsoft.card.adaptive",
    "type": "AdaptiveCard",
    "version": "1.0",
    "body": [
        {
            "type": "TextBlock",
            "text": "Default"
        }
    ],
    "actions": [{
        "type": "Action.Submit",
        "title": "OK"
    }]
}

节点

const WelcomeDialogCard = require('./Welcome.json');

const confirmationCard = CardFactory.adaptiveCard(WelcomeDialogCard)
await turnContext.sendActivity({ attachments: [confirmationCard] });

我强烈建议使用AdaptiveCard Designer来帮助您创建卡，并请注意，您不必对AdaptiveCard进行字符串化和解析。

希望这会有所帮助！
