在嵌套對話框中處理自適應卡提交操作值

Question

我已經使用C＃使用SDK .net Core 2.2 虛擬助手模板創建了聊天機器人，該模板具有1個主對話框和多個對話框（組件對話框）。 每個組件對話框調用另一個組件對話框。 假設我有MainDialog，第2個組件對話框的名稱為ComponentDialog1，ComponentDialog2。

我正在使用DialogsTriggerState來了解整個機器人在哪個組件對話框中觸發。

主對話框代碼：我在主對話框的RouteAsync方法中調用ComponentDialog1。

protected override async Task RouteAsync(DialogContext dc, CancellationToken cancellationToken = default(CancellationToken))
{
    var triggerState = await _triggerStateAccessor.GetAsync(dc.Context, () => new DialogsTriggerState());
    await dc.BeginDialogAsync(nameof(ComponentDialog1), triggerState);
    var turnResult = EndOfTurn;
    if (turnResult != EndOfTurn)
    {
        await CompleteAsync(dc);
    }
}

ComponentDialog1代碼：我有3個瀑布步驟，其中第2步將根據機器人的狀態調用特定的“ ComponentDialog”。 假設我正在觸發“ ComponentDialog2”。

private async Task<DialogTurnResult> TriggerToSpecificComponentDialogAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{
    var triggerState = await _DialogsTriggerStateAccessor.GetAsync(stepContext.Context, () => null);

    if (triggerState.TriggerDialogId.ToString().ToLower() == "componentdialog2")
    {
        return await stepContext.BeginDialogAsync(nameof(ComponentDialog2), triggerState);
    }
    else if (triggerState.TriggerDialogId.ToString().ToLower() == "componentdialog3")
    {
        return await stepContext.BeginDialogAsync(nameof(ComponentDialog3), triggerState);
    }
    else
    {
        return await stepContext.NextAsync();
    }
}

ComponentDialog2代碼：我有2個瀑布步驟，顯示自適應卡並從卡和結束對話框中獲取值（ComponentDialog2）

private async Task<DialogTurnResult> DisplayCardAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{
    // Display the Adaptive Card
    var cardPath = Path.Combine(".", "AdaptiveCard.json");
    var cardJson = File.ReadAllText(cardPath);
    var cardAttachment = new Attachment()
    {
        ContentType = "application/vnd.microsoft.card.adaptive",
        Content = JsonConvert.DeserializeObject(cardJson),
    };
    var message = MessageFactory.Text("");
    message.Attachments = new List<Attachment>() { cardAttachment };
    await stepContext.Context.SendActivityAsync(message, cancellationToken);

    // Create the text prompt
    var opts = new PromptOptions
    {
        Prompt = new Activity
        {
            Type = ActivityTypes.Message,
            Text = "waiting for user input...", // You can comment this out if you don't want to display any text. Still works.
        }
    };

    // Display a Text Prompt and wait for input
    return await stepContext.PromptAsync(nameof(TextPrompt), opts);
}

private async Task<DialogTurnResult> HandleResponseAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{
    await stepContext.Context.SendActivityAsync($"INPUT: {stepContext.Result}");
   //I am doing some logic and may continue to next steps also from here, but as I am stuck here i am ending dialog.
    return await stepContext.EndDialogAsync();
}

問題：在第一步的“ ComponentDialog2”中單擊自適應卡提交后，代碼（控件）沒有指向第二步“ HandleResponseAsync”，因為我已經提供了提示並等待輸入，所以它應該發生。

實際輸出：我既沒有得到任何輸出，也沒有在bot中出錯。

預期產量：

1）從ComponentDialog顯示給機器人2：輸入：無論我提交了什么

2）當我在ComponentDialog2中結束對話框時，控件（代碼）應返回到ComponentDialog1，並應轉到ComponentDialog1的第3個瀑布步驟。

樣本自適應卡

  {
   "type": "AdaptiveCard",
   "body": [
    {
        "type": "TextBlock",
        "size": "Medium",
        "weight": "Bolder",
        "text": "Let us know your feedback"
    }

        "data": "good"
    },

     {
        "type": "Action.Submit",
        "title": "Average",
        "data": "avaerage"
    }
    ,{
        "type": "Action.Submit",
        "title": "Bad",
        "data": "bad"
    }
]
}

請幫我怎么實現

Answer 1

經過大量測試后，我相當確定您在某個地方缺少此調用 （應該以某種方式在OnMessageAsync() 調用它：

var results = await dialogContext.ContinueDialogAsync(cancellationToken);

核心機器人樣本執行此操作的方法是將其添加到DialogExtensions ，該DialogExtensions在OnMessageAsync()被調用

---

更新：我還注意到，如果await ConversationState.SaveChangesAsync(turnContext, true, cancellationToken);可能會發生這種情況await ConversationState.SaveChangesAsync(turnContext, true, cancellationToken); 在OnTurnAsync()但是在OnDialogAsync() （或者如果不在兩個位置中）； 通常，您還需要確保將其設置為false而不是true 。
