LUISサービスをボットに統合するには？

私はLUISを使ってCORTANAアプリケーションを開発していますが、ルートダイアログはLUISを消費しています。ユーザ意図に基づいて別のダイアログにリダイレクトしますが、Rootダイアログコンストラクタの実行後に、 LUIS（つまり、InsightsDialogは以下のようにコメントしています）が正常に動作しています。LUISサービスをボットに統合するには？

次のコードは、MessagesControllerからルートダイアログにリダイレクトされます。

public async Task<HttpResponseMessage> Post([FromBody]Activity activity) 
     { 
      if (activity.Type == ActivityTypes.Message) 
      { 
        await Conversation.SendAsync(activity,() => new Dialogs.RootDialog()); 
        //await Conversation.SendAsync(activity,() => new Dialogs.InsightsDialog()); 
      } 
      else 
      { 
       await HandleSystemMessage(activity); 
      } 

      var response = Request.CreateResponse(HttpStatusCode.OK); 
      return response; 
     }

ルートダイアログコード：

[Serializable] 
    public class RootDialog : LuisDialog<object> 
    { 
     InsightsDialog customerInsightsDialog = null; 
     public RootDialog() : base(new LuisService(Utility.GetLUISAttributesFromConfig())) 
     { 
      customerInsightsDialog = new InsightsDialog(); 
     } 
     public static LuisModelAttribute GetLUISAttributesFromConfig() 
     { 
       return new LuisModelAttribute(Constants.RootDialogLuisModelId, Constants.RootDialogLuisSubscriptionKey); 
     } 

     #region Intents 
     [LuisIntent("")] 
     [LuisIntent("None")] 
     public async Task None(IDialogContext context, LuisResult result) 
     { 
       string userInput = result.Query; 
       context.Call(customerInsightsDialog, ResumeAfterInsightsDialog); 
     } 

     [LuisIntent("Greetings")] 
     public async Task Greetings(IDialogContext context, LuisResult result) 
     { 
       string userInput = result.Query; 
       context.Call(customerInsightsDialog, ResumeAfterInsightsDialog); 
     } 

     private Task ResumeAfterInsightsDialog(IDialogContext context, IAwaitable<object> result) 
     { 
      return Task.CompletedTask; 
     } 
     #endregion 
    }

は私がログに次の例外を発見し、それが発生し、右RootDialogクラスのコンストラクタを呼び出した後：

このコードは正常に動作していますエミュレータとWebチャットのチャンネルがありましたが、CORTANAチャンネルでのみ例外が発生しました。私を助けてくれてありがとう。次のように

"stringToEscape"変数を使用した場所について、より多くのコードを投稿することができます。 –

userInput文字列が子ダイアログに渡されていないと思われます。子ダイアログ "customerInsightsDialog"にメッセージを渡す場合は、2つの方法があります。1番目の方法は、メッセージをコンストラクタ内に渡すことです。子のダイアログ：context.Call（customerInsightsDialog（stringInput）、SomeResumeAfter）、2番目の方法はcontext.Forwardを使用することです：context.Forward（customerInsightsDialog、this.ResumeAftercustomerInsightsDialogEnded、context.MakeMessage（）、CancellationToken.None）; –

stringToEscapeがBot Frameworkによって内部的に呼び出されています。実際には、ダイアログから "context.call"メソッドを削除しても、Intentメソッドを呼び出さない場合、同じ問題が発生します。 –

問題は、クラス「MessagesController」の既存のコードを修正することで解決されました：

public async Task<HttpResponseMessage> Post([FromBody]Activity activity) 
     { 
      if (activity.Type == ActivityTypes.Message) 
      { 
        if (string.IsNullOrEmpty(activity.Text)) 
        { 
          var connector = new ConnectorClient(new Uri(activity.ServiceUrl)); 

          Activity reply = activity.CreateReply(); 
          reply.Text = string.Format(Resources.WELCOME_MESSAGE, Constants.UserInfo.FullName); 
          reply.Speak = SSMLHelper.Speak(string.Format(Resources.WELCOME_MESSAGE, Constants.UserInfo.FullName)); 
          reply.InputHint = InputHints.ExpectingInput; 

          await connector.Conversations.ReplyToActivityAsync(reply); 
        } 
       else 
        { 
          await Conversation.SendAsync(activity,() => new Dialogs.RootDialog()); 
        } 
      } 
      else 
      { 
       await HandleSystemMessage(activity); 
      } 

      var response = Request.CreateResponse(HttpStatusCode.OK); 
      return response; 
     }

実は「テキスト」プロパティ「活動」のオブジェクトが空でした。だから、今私は（Speakを介して）何かのテキストを入力してさらに進んでいくことをユーザーに求めています。
