如何根据每个不同的 luis 意图启动不同的对话？

Question

我正在尝试设置一个简单的聊天机器人，用户可以在其中说出不同的意图，并在此基础上进行不同的对话。目前我有 2 个可能的意图及其相应的对话框："listBots" 和 "runBot".

我将我的机器人设置为从 Luis 获取意图，然后使用 switch on intent 来确定它应该使用哪个对话框运行，这是我尝试执行此操作的代码：

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;
    }

基本上在我的 OnMessageActivityAsync 中，它只是调用 Luis 从用户输入中获取意图，然后打开意图，根据情况，它创建一个不同的对话框并启动它。至少理论上是这样。

在我的 startup.cs 中，我依赖注入所有机器人和对话框类。

    // 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>();
    }

这给我一个 500 错误，所以我不知道出了什么问题。我正在使用 bot-framework v4.

这段代码似乎可以正常工作！不知道为什么它昨天不起作用。我会把它留给将来可能正在寻找答案的人。
