当我在瀑布对话框中使用自适应卡片的输入形式时，ContinueDialogAsync 不起作用

Question

我一直在使用 EchoBot 模板，最近使用了 VirtualAssistant 模板。在之前的模板中，提交输入表单数据是没有问题的，但是这个模板仅仅通过提交输入表单数据就无法使用ContinueDialogAsync。我们如何解决这个问题？请帮助我。

WaterfallStep的输入形式

       card.Body.Add(new AdaptiveTextBlock()
            {
                HorizontalAlignment = AdaptiveHorizontalAlignment.Left,
                Spacing = AdaptiveSpacing.None,
                Size = AdaptiveTextSize.Small,
                Weight = AdaptiveTextWeight.Bolder,
                Color = AdaptiveTextColor.Accent,
                Text = Common.PurchaseDialog_DepartureDate
            });

        card.Body.Add(new AdaptiveDateInput()
        {
            Id = "GoDateVal",
            Value = DateTime.Now.AddDays(4).ToString("yyyy-MM-dd"),
            Spacing = AdaptiveSpacing.None
        });

        if (lowestPriceQuery.tripType == "RT")
        {
            card.Body.Add(new AdaptiveTextBlock()
            {
                HorizontalAlignment = AdaptiveHorizontalAlignment.Left,
                Spacing = AdaptiveSpacing.None,
                Size = AdaptiveTextSize.Small,
                Weight = AdaptiveTextWeight.Bolder,
                Color = AdaptiveTextColor.Accent,
                Text = Common.PurchaseDialog_CommingDate
            });

            card.Body.Add(new AdaptiveDateInput()
            {
                Id = "ComeDateVal",
                Value = DateTime.Now.AddDays(8).ToString("yyyy-MM-dd"),
                Spacing = AdaptiveSpacing.None,
            });
        }

if (lowestPriceQuery.tripType == "DS")
        {
            card.Body.Add(new AdaptiveTextBlock()
            {
                HorizontalAlignment = AdaptiveHorizontalAlignment.Left,
                Spacing = AdaptiveSpacing.None,
                Size = AdaptiveTextSize.Small,
                Weight = AdaptiveTextWeight.Bolder,
                Color = AdaptiveTextColor.Accent,
                Text = "ReturnDate"
            });

            card.Body.Add(new AdaptiveDateInput()
            {
                Id = "ComeDateVal",
                Value = DateTime.Now.AddDays(8).ToString("yyyy-MM-dd"),
                Spacing = AdaptiveSpacing.None,
            });
        }

        card.Actions.Add(new AdaptiveSubmitAction()
        {
            Type = AdaptiveSubmitAction.TypeName,
            Title = "submit",
            Id = "submit",
        });

        reply.Attachments = new List<Attachment>
        {
            new Attachment()
            {
                ContentType = "application/vnd.microsoft.card.adaptive",
                Content = JsonConvert.DeserializeObject(JsonConvert.SerializeObject(card))
            }
        };
        await turnContext.SendActivityAsync(reply, cancellationToken: cancellationToken);

DilaogBot,

调试时，从输入表单提交时 var result = await dc.ContinueDialogAsync (); 没有任何反应。

var dc = await _dialogs.CreateContextAsync(turnContext);

                if (turnContext.Activity.Type == ActivityTypes.Message)
                {
                    // Ensure that message is a postBack (like a submission from Adaptive Cards)
                    var channelData = JObject.Parse(dc.Context.Activity.ChannelData.ToString());
                    if (channelData.ContainsKey("postback"))
                    {
                        var postbackActivity = dc.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 dc.Context.SendActivityAsync(postbackActivity);
                    }
                }

                if (dc.ActiveDialog != null)
                {
                    var result = await dc.ContinueDialogAsync();
                }
                else
                {
                    await dc.BeginDialogAsync(typeof(T).Name);
                }

您需要删除：

await dc.Context.SendActivityAsync(postbackActivity);

当机器人发送消息时，它会将对话标记为已响应并且不会继续适当地继续。

此外，您的“//Ensure message is a PostBack”代码应该更像这样：

var activity = turnContext.Activity;

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

我相信你是从我的一个旧答案中得到的代码，我已经改进了它。
