处理 AdaptiveCard 操作得到“抱歉，我的机器人代码有问题。”

Question

我在一个项目处理来自 AdaptiveCards 的操作时遇到了麻烦。我的方法在我所有其他项目中都非常有效，只是不是最近的。我尝试回滚 bot.builder 和 bot.connector 的版本以匹配其他项目，但这并没有帮助。

卡片显示正常，但当您点击按钮时，您会看到老旧的“抱歉，我的机器人代码有问题”。我在 RootDialog 中显示卡片，并调用 context.wait(MessageReceivedAsync)

调试，如果我在显示卡后向机器人键入内容 MessageReceivedAsync 被触发。单击按钮，永远不会到达那里。直接在 MessageController 中设置一个断点，它会到达那里，但进入它会立即死亡并显示“抱歉，我的机器人代码有问题。”

这是我的 MessageController：

    public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
    {

        if (activity.Type == ActivityTypes.Message)
        {
            ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));
            await Conversation.SendAsync(activity, () => new RootDialog());
        }

这是自适应卡片操作：

  "actions": [
{
  "type": "Action.Submit",
  "title": "Create On-Line Request",
  "data": {
    "action": "requestContact"
  }
}

] }

在我的 RootDialog 中：

            await context.PostAsync(CardHelper.MakeCard(context, "~\\AdaptiveCards\\ContactInfo311.json", replacements));
            context.Wait(MessageReceivedAsync);

卡片显示正常，但当您点击按钮时，您会看到老旧的“抱歉，我的机器人代码有问题”。

我用下面的示例代码做了一个测试，它适用于我，你可以参考它。如果可能的话，你可以在你身边测试它，看看它是否适合你。

在 RootDialog 中：

[Serializable]
public class RootDialog : IDialog<object>
{
    public Task StartAsync(IDialogContext context)
    {
        context.Wait(MessageReceivedAsync);

        return Task.CompletedTask;
    }

    private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
    {
        var activity = await result as Activity;

        var replymes = context.MakeMessage();

        if (activity.Text != null)
        {
            if (activity.Text.ToLower().Contains("cards"))
            {
                replymes = context.MakeMessage();

                var cardjson = await GetCardText("ContactInfo311");

                var results = AdaptiveCard.FromJson(cardjson);
                var card = results.Card;

                replymes.Attachments.Add(new Attachment()
                {
                    Content = card,
                    ContentType = AdaptiveCard.ContentType,
                    Name = "Card"
                });
            }
            else
            {
                replymes.Text = $"You sent {activity.Text}";
            }
        }
        else if (activity.Value != null)
        {
            replymes.Text = $"submit data: {activity.Value}";
        }

        // return our reply to the user
        await context.PostAsync(replymes);

        context.Wait(MessageReceivedAsync);
    }

    public async Task<string> GetCardText(string cardName)
    {
        var path = System.Web.HttpContext.Current.Server.MapPath($"~/AdaptiveCards/{cardName}.json");

        if (!File.Exists(path))
            return string.Empty;

        using (var f = File.OpenText(path))
        {
            return await f.ReadToEndAsync();
        }
    }
}

ContactInfo311.json

{
  "type": "AdaptiveCard",
  "version": "1.0",
  "body": [
    {
      "type": "TextBlock",
      "size": "large",

      "text": "This is Adaptive Card"
    }
  ],
  "actions": [
    {
      "type": "Action.Submit",
      "data": {
        "action": "requestContact"
      },
      "title": "Clike me"
    }

此外，为了解决您的项目问题，您可以设置断点并逐步调试代码以跟踪activity并检查错误是否由activity.Text=null引起。
