如何根据每个不同的 luis 意图启动不同的对话？

Question

I am trying to setup a simple chatbot where the user can say different intent and based on that it will have different dialog. Currently I have 2 possible intent and their corresponding dialogs: "listBots" and "runBot".

I setup my bot to get the intent from Luis, then use switch on intent to determine which dialog it should run, here is my code that try to do this:

public class MainChatbot : ActivityHandler
{
    private readonly IOptions<Models.Configurations> _mySettings;
    protected readonly IRecognizer _recognizer;
    protected readonly BotState _conversationState;

    public MainChatbot(ConversationState conversationState, IOptions<Models.Configurations> mySettings, ChatbotRecognizer recognizer)
    {
        _mySettings = mySettings ?? throw new ArgumentNullException(nameof(mySettings));
        _recognizer = recognizer;
        _conversationState = conversationState;
    }

    protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
    {
        var luisResult = await _recognizer.RecognizeAsync<Models.ChatbotIntent>(turnContext, cancellationToken);
        Models.ChatbotIntent.Intent TopIntent = luisResult.TopIntent().intent;
        await turnContext.SendActivityAsync(MessageFactory.Text($"Your Intention Is: {TopIntent.ToString()}"), cancellationToken);

        switch (TopIntent)
        {
            case Models.ChatbotIntent.Intent.RunBot:
                var RunBotOptions = new Models.RunBotOptions();
                Dialog RunBotDialog = new RunBotDialog();
                await RunBotDialog.RunAsync(turnContext, _conversationState.CreateProperty<DialogState>(nameof(DialogState)), cancellationToken);
                break;
            case Models.ChatbotIntent.Intent.ListBots:
                Dialog ListBotDialog = new ListBotDialog();
                await ListBotDialog.RunAsync(turnContext, _conversationState.CreateProperty<DialogState>(nameof(DialogState)), cancellationToken);
                break;
            default:
                break;
        }
        return;
    }

Basically in my OnMessageActivityAsync, it simply invoke Luis to get the intent from the user input, then switch on the intent, based on the case, it create a different dialog and start it. At least in theory.

Here in my startup.cs, I dependency inject all the bot and the dialog classes.

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

        // Add functionality to inject IOptions<T>
        services.AddOptions();

        // Add our Config object so it can be injected
        services.Configure<Models.Configurations>(Configuration);

        // Create the Bot Framework Adapter with error handling enabled.
        services.AddSingleton<IBotFrameworkHttpAdapter, AdapterWithErrorHandler>();

        // Create the bot as a transient. In this case the ASP Controller is expecting an IBot.
        services.AddTransient<IBot, Dialogs.MainChatbot>();

        // Create the Conversation state. (Used by the Dialog system itself.)
        var storage = new MemoryStorage();
        var conversationState = new ConversationState(storage);
        services.AddSingleton(conversationState);


        // Register LUIS recognizer
        services.AddSingleton<ChatbotRecognizer>();

        // Dialogs
        services.AddSingleton<Dialogs.RunBotDialog>();
        services.AddSingleton<Dialogs.ListBotsDialog>();
    }

This is giving me a 500 error, so I don't know what's wrong. I am using bot-framework v4.

It seems this code works as is! Not sure why it didn't work yesterday. I'll leave it up for anyone who might be looking for answer in the future.
