我一直在尝试向 MS TEAMS 中的频道发送带有按钮的主动自适应消息卡，但我找不到任何解决方案.

REST API (

根据希尔顿的推荐，我可以解决这个问题

您可以在这里设计自己的自适应卡片:自适应卡片设计并编辑 attachments.body 根据您的要求.

发送主动消息

方法:发布网址:https://smba.trafficmanager.net/{api}/v3/conversations/{channelId}/activities

作为机器人发送回复

方法:发布网址:https://smba.trafficmanager.net/{api}/v3/conversations/{channelId};messageid={messageid}/activities

{类型":消息"，附件":[{"contentType": "application/vnd.microsoft.card.adaptive",内容": {"type": "AdaptiveCard",版本":1.0"，身体": [{类型":文本块"，大小":中"，重量":更大胆"，文字":文字"},{类型":文本块"，尺寸":小"，文本":文本"，包装":真},],行动":[{"type": "Action.Submit","title": "接受",数据": {接受":真}},{"type": "Action.Submit",身份证":身份证"，标题":标题"，数据": {msteams":{类型":任务/获取"，}}}]}}]}

I have been trying to send proactive adaptive message card with buttons to a channel in MS TEAMS, but I am not able to find any solution to this.

Any solution in REST API (https://smba.trafficmanager.net) or BotBuilder SDK for nodejs is appreciated.

Based on recommendation from Hilton , I could figure out this

You could design your own adaptive card here: Adaptive Card Design and edit attachments.body as per your requirement.

sending a proactive message

METHOD: POST URL: https://smba.trafficmanager.net/{api}/v3/conversations/{channelId}/activities

sending reply as bot

METHOD: POST URL: https://smba.trafficmanager.net/{api}/v3/conversations/{channelId};messageid={messageid}/activities
