Java环境下如何获取Teams Adaptive Card自适应卡片的用户输入值

以下是我在Teams中发送的Adaptive Card自适应卡片的JSON：

{
    "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
    "type": "AdaptiveCard",
    "version": "1.0",
    "body": [
        {
            "type": "Container",
            "items": [

问题描述 #

用户输入内容并点击OK提交后，当前机器人仅返回"Echo:"。已实现获取Activity的相关逻辑，但用户点击OK按钮时该方法不会被触发。 #

解决方案 #

• 调整Activity监听范围：Teams中Adaptive Card的Action.Submit触发的是invoke类型的Activity，而非普通message类型。你需要在机器人的消息处理入口，新增对type = invoke且name = adaptiveCard/action类型请求的处理逻辑，原有仅监听message类型的逻辑自然无法捕获提交事件。
• 提取用户提交数据：成功捕获invoke请求后，用户在卡片中填写的内容会存储在activity.value.data字段中，你可以直接通过你定义的输入控件id（比如dueDate、comment）提取对应内容。
• 构造合法响应：处理完invoke请求后需要先返回200状态码的空响应告知Teams请求处理成功，再主动调用消息发送接口，将提取到的用户输入内容作为回复发送到当前会话，即可替换原有仅返回"Echo:"的效果。
