在提交后不显示卡的情况下从自适应卡中检索数据的正确方法是什么？

Question

我在我的机器人中使用了自适应智能卡和瀑布对话框。我想检索用户在表单中提供的数据，并在用户单击submit按钮后在另一个自适应卡中显示它。但是当我点击提交按钮时，空卡再次出现提示。

我已经阅读了这篇文章Stackoverflow和尝试使用回发通道数据的解决方案。它只在模拟器中起作用，我可以检索所有数据。但当我将其部署到Azure和MsTeams通道后，每次点击之后，它都会一次又一次地重新提示。

我的OnTurnAsync方法：

public override async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default(CancellationToken))
        {

            await base.OnTurnAsync(turnContext, cancellationToken);


            var activity = turnContext.Activity;

            if (string.IsNullOrWhiteSpace(activity.Text) && activity.Value != null)
            {
                activity.Text = JsonConvert.SerializeObject(activity.Value);

            }

            await ConversationState.SaveChangesAsync(turnContext, false, cancellationToken);
            await UserState.SaveChangesAsync(turnContext, false, cancellationToken);

        }

我的DialogExtensions.cs我取自Gags08的代码，它在模拟器上工作得很好，但不是在团队上：

using System.Threading;
using System.Threading.Tasks;
using Microsoft.Bot.Builder;
using Microsoft.Bot.Builder.Dialogs;
using Newtonsoft.Json.Linq;

namespace Microsoft.BotBuilderSamples
{
    public static class DialogExtensions
    {
        public static async Task Run(this Dialog dialog, ITurnContext turnContext, IStatePropertyAccessor<DialogState> accessor, CancellationToken cancellationToken = default(CancellationToken))
        {

            var dialogSet = new DialogSet(accessor);
            dialogSet.Add(dialog);


            var dialogContext = await dialogSet.CreateContextAsync(turnContext, cancellationToken);
            // Ensure that message is a postBack (like a submission from Adaptive Cards)
            if (dialogContext.Context.Activity.GetType().GetProperty("ChannelData") != null)
            {
                var channelData = JObject.Parse(dialogContext.Context.Activity.ChannelData.ToString());
                if (channelData.ContainsKey("postBack"))
                {
                    var postbackActivity = dialogContext.Context.Activity;
                    // Convert the user's Adaptive Card input into the input of a Text Prompt
                    // Must be sent as a string
                    postbackActivity.Text = postbackActivity.Value.ToString();
             await dialogContext.Context.SendActivityAsync(postbackActivity);
                }
            }
            var results = await dialogContext.ContinueDialogAsync(cancellationToken);
            if (results.Status == DialogTurnStatus.Empty)
            {
                await dialogContext.BeginDialogAsync(dialog.Id, null, cancellationToken);
            }
         }
    }

我是机器人新手，也许我错了，但在我看来，问题出在消息属性"ChannelData“中。回发密钥仅在仿真器中可用，因此它不会通过团队截获它。我已经通过模拟器连接到我的Azure机器人，它工作得很好。告诉我如何通过团队正确使用卡片，这个问题有什么解决方案吗？

Answer 1

最后，我修改了Teams通道的DialogExtensions.cs，并删除了OnTurnAsync方法中的所有代码。当我们从我们的卡片发送post数据时，就像前面的例子一样，我们试图捕获"postback“属性，它只存在于模拟器中。但是在团队中，channelData只包含对话的id和带有活动类型的“源”键。仅当我们尝试从自适应卡提交数据时，此密钥才存在。当我改变它时，我可以像在模拟器中一样在字符串类型中使用card中的值：

   namespace Microsoft.BotBuilderSamples
{
    public static class DialogExtensions
    {
        public static async Task Run(this Dialog dialog, ITurnContext turnContext, IStatePropertyAccessor<DialogState> accessor, CancellationToken cancellationToken = default(CancellationToken))
        {

            var dialogSet = new DialogSet(accessor);
            dialogSet.Add(dialog);


            var dialogContext = await dialogSet.CreateContextAsync(turnContext, cancellationToken);


            if (dialogContext.Context.Activity.GetType().GetProperty("ChannelData") != null)
            {
                var channelData = JObject.Parse(dialogContext.Context.Activity.ChannelData.ToString());
                 //Check property in teams channel
                if (channelData.ContainsKey("source"))
                {
                    var postbackActivity = dialogContext.Context.Activity;
                    // Convert the user's Adaptive Card input into the input of a Text Prompt
                    // Must be sent as a string
                    postbackActivity.Text = postbackActivity.Value.ToString();


                }
            }
            var results = await dialogContext.ContinueDialogAsync(cancellationToken);
            if (results.Status == DialogTurnStatus.Empty)
            {
                await dialogContext.BeginDialogAsync(dialog.Id, null, cancellationToken);
            }

我明白在这种情况下，这不是明确的解决方案。但我只有通过这种方式才能让自适应卡在MS团队中工作。
