如何在 Bot Framework C# 中在运行时生成瀑布步骤？

Question

我有一个由 Bot Framework v4 制作的聊天机器人，我正在阅读机器人响应和他想问用户的问题。

这是一个单独的文件：

BotQuestions.cs

 public class BotQuestions{

    public string Intro = "Welcome to Chat Session! I am Mr. A, your assistant.";

    public string AskFood = "How was your experience with our food?";

    public string Acknowledge = "I am glad that you liked our food!";

    public string Sad = "We apologize that you didn't enjoy our food. We will take care of it next time";
 }

然后我在定义 WaterFall 步骤的 Bot class 中调用此 class。

ChatBotDialog.cs

public class ChatBotDialog : CancelAndHelpDialog
{

   public static BotQuestions question = new BotQuestions();

   public ChatBotDialog(UserState userState, ConversationState conversationState) : 

   base(nameof(ChatBotDialog))
   {
       memoryStorage = new MemoryStorage();

       _conversationState = conversationState;

       // the waterfall method to maintain the order of the chat
       var waterfallSteps = new WaterfallStep[]
       {
           IntroStepAsync,
           AskFoodStepAsync,
           AckStepAsync,
           SadAsync
       }; 

    // adding named dialogs to the Dialog Set. These names are saved in dialog set
    AddDialog(new WaterfallDialog(nameof(WaterfallDialog), waterfallSteps));
    AddDialog(new TextPrompt(nameof(TextPrompt)));


    // run the initial child dialog
    InitialDialogId = nameof(WaterfallDialog);
   }

  private static async Task<DialogTurnResult> IntroStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
  {
      Activity reply = stepContext.Context.Activity.CreateReply();
        reply.Type = ActivityTypes.Typing;
        ConnectorClient connector = new ConnectorClient(new Uri(stepContext.Context.Activity.ServiceUrl));
        await connector.Conversations.ReplyToActivityAsync(reply);


        //BotReplyTime();
        var promptOptions = new PromptOptions
        {
            Prompt = MessageFactory.Text(questions.Intro) // here I am accessing the Bot Question class string property and its value.
        };
        return await stepContext.PromptAsync(nameof(TextPrompt), promptOptions, cancellationToken);

     }


private static async Task<DialogTurnResult> AskFoodStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken){
  // similar logic
 }


private static async Task<DialogTurnResult> AcknowledgeStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken){
  // similar logic
}


private static async Task<DialogTurnResult> SadStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken){
  // similar logic
  }
 }

如您所见，ChatBotDialog 有瀑布式步骤，每个步骤都调用 BotQuestions class 来访问字符串值。

现在的情况是如果我想在BotQuestions.cs中添加一个新问题，我必须生成字符串值，生成相应的瀑布步骤，然后运行看起来非常笨拙的对话框...那么有没有办法在运行时间内动态生成瀑布步骤？（仅在 C# 中）如果我在 BotQuestions.cs 之间的任何位置添加一个新问题，机器人是否可以检测到相应地改变和调整它？这可能吗？

Answer 1

无法动态添加瀑布步骤。

我花了一秒钟才明白你在做什么。我不建议您根据向用户提出的一系列问题来构建您的瀑布，而是根据预期的用户输入（即 "I need my user's shoes size, address and date of birth"）来构建它。

我建议您查看新的 Bot Framework Composer。它是一个基于 UI 的机器人创建工具，可围绕对话构建机器人（与您正在做的没什么不同）。
