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.
