Question

我正在尝试在聊天机器人中放入一个简单的自适应卡，以收集用户的姓名和电子邮件。我不知道如何实际从卡中获取输入。

在显示对话框的瀑布步骤中。我无法弄清楚哪个属性应该具有从Action.Submit按钮返回的JSON字符串。

我包含了json对话框和TypeScript文件。我的MainDialog在第146行启动ClientCheckDialog，ClientCheckDialog在第86行启动GetContactInfoDialog

这是json文件对话框：

{
  "$schema": "https://adaptivecards.io/schemas/adaptive-card.json",
  "type": "AdaptiveCard",
  "version": "1.0",
  "body": [
    {
      "type": "TextBlock",
      "text": "Name",
      "wrap": true
    },
    {
      "type": "Input.Text",
      "id": "id_name"
    },
    {
      "type": "TextBlock",
      "text": "Email Address",
      "wrap": true
    },
    {
      "type": "Input.Text",
      "id": "id_email",
      "style": "email",
      "placeholder": "youremail@example.com"
    }
  ],
  "actions": [
    {
      "type": "Action.Submit",
      "title": "Submit",
      "data": {
        "clickedSubmit" : true
      }
    }
  ]
}

Answer 1

更新

现在，我已经审查了您的代码，找到了答案。首先，几点：

Virtual Assistant仍处于预览状态，其TypeScript版本的优先级低于C＃。期待错误。而且，将来有很大的好于零的机会会发生很大的变化。就个人而言，我会用它来表达想法，但首先要从CoreBot之类的东西开始进行开发，然后再集成到您实际需要的东西中。
我不知道为什么添加this.onDialog(this.activityToText.bind(this));会产生双重欢迎消息。我认为这与第1点有关。
这没有用的原因是我自己的错。我之所以加入trim()是因为它反映了此答案的C＃版本，但实际上由于它不会导致虚假的值而将其破坏。抱歉造成混乱，我将编辑其他答案。
您最后不需要turnContext.activity.text = JSON.stringify(turnContext.activity.value);。

有关Point 4的更多信息

我将对此进行扩展，因为这是理解Javascript的重要方面。

如果有：

const activity = turnContext.activity;
if (!activity.text && activity.value) {
    activity.text = JSON.stringify(activity.value);
}
turnContext.activity.text = JSON.stringify(turnContext.activity.value);

... turnContext.activity.text = JSON.stringify(turnContext.activity.value);是多余的，因为设置

const activity = turnContext.activity

不是在说：

const activity = copyOf(turnContext.activity)

相反，它是在说：

const activity = memoryLocationOf(turnContext.activity)

因此，当您调用activity.text = JSON.stringify(activity.value);时，它会将activity.text（即turnContext.activity.text）的内存位置更改为JSON.stringify(activity.value)。因此，实际上您同时在更改activity.text和turnContext.activity.text，因为它们指向内存中的相同位置。

之所以提出这一点，并不是因为它具有超级相关性，而是因为如果您现在不学习这一点，将来您可能会遇到一些真正的难题。

答案

话虽如此：

删除this.onDialog(this.activityToText.bind(this));
删除activityToText()
使turn()的结尾看起来像这样：

if (dc.activeDialog !== undefined) {
    const activity = turnContext.activity;
    if (!activity.text && activity.value) {
        activity.text = JSON.stringify(activity.value);
    }
await dc.continueDialog();
} else {
    await dc.beginDialog(this.rootDialogId);
}

await next();

然后您将得到：

我不会将其标记为重复项，因为它在TypeScript中，并且距离我为TypeScript回答了已经有一段时间了。话虽如此，我之前已经回答了这个问题，并编辑了原始答案以使其保持最新（此答案中的最后一个链接）。

话虽如此，原理是相同的。参见this answer。

我强烈建议您阅读答案底部链接的博客文章。

特定于您的代码：

您不能简单地先使用await stepContext.context.sendActivity(<card>)然后使用return await stepContext.next(undefined);。没有任何内容告诉机器人等待回复。您要么需要在卡片后发送空白文本提示（如上一个链接中的示例中所示），要么将卡片附加到文本提示中，然后同时发送它们。像这样：

async displayCard(step) {
    const cardPrompt = MessageFactory.text('');
    cardPrompt.attachments = [yourAdaptiveCard];
    return await step.prompt('textPrompt', cardPrompt);
}
