您好,当我提示用确认提示或否提示的用户提示用户时。路易斯(Luis)检测到"否"为取消意图,这取消了我的整个对话框。然后,我从取消意图中删除了"否",但现在"否被路易斯被发现为问候。因为用户可以随时取消。我该如何解决?谢谢!
这是代码。
public async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken)
{
var dc = await _dialogs.CreateContextAsync(turnContext, cancellationToken);
var activity = turnContext.Activity;
var userstate = await _basicAccessors.BasicUserStateAccessor.GetAsync(turnContext, () => new BasicUserState(), cancellationToken);
var state = await _basicAccessors.BasicStateAccessor.GetAsync(turnContext, () => new BasicState(), cancellationToken);
if (turnContext.Activity.Type == ActivityTypes.Message)
{
turnContext.TurnState.Add("BasicAccessors", _basicAccessors);
string text = string.IsNullOrEmpty(turnContext.Activity.Text) ? string.Empty : turnContext.Activity.Text.ToLower();
var luisResults = await _services.LuisServices[LuisConfiguration].RecognizeAsync(dc.Context, cancellationToken);
var topScoringIntent = luisResults?.GetTopScoringIntent();
var topIntent = topScoringIntent.Value.intent;
string userName = string.Empty;
if (activity.From.Name != null)
{
userName = activity.From.Name;
}
userstate.Name = userName;
await _basicAccessors.BasicUserStateAccessor.SetAsync(turnContext, userstate);
await _basicAccessors.BasicStateAccessor.SetAsync(turnContext, state);
var interrupted = await IsTurnInterruptedAsync(dc, topIntent);
if (interrupted)
{
// Bypass the dialog.
// Save state before the next turn.
await _basicAccessors.ConversationState.SaveChangesAsync(turnContext, false, cancellationToken);
await _basicAccessors.UserState.SaveChangesAsync(turnContext, false, cancellationToken);
return;
}
// Continue the current dialog
var dialogResult = await dc.ContinueDialogAsync();
// if no one has responded,
if (!dc.Context.Responded)
{
// examine results from active dialog
switch (dialogResult.Status)
{
case DialogTurnStatus.Empty:
switch (topIntent)
{
case GreetingIntent:
await dc.BeginDialogAsync(MainDialogId);
break;
case "loan calculator":
case "loan calc":
await dc.BeginDialogAsync(MainDialogId);
break;
case NoneIntent:
default:
await dc.Context.SendActivityAsync("I didn't understand what you just said to me.");
break;
}
break;
case DialogTurnStatus.Waiting:
// The active dialog is waiting for a response from the user, so do nothing.
break;
case DialogTurnStatus.Complete:
await dc.EndDialogAsync();

await dc.CancelAllDialogsAsync();
break;
}
}
}
else if (activity.Type == ActivityTypes.ConversationUpdate)
{
if (activity.MembersAdded != null)
{

if (member.Id != activity.Recipient.Id)
{
await SendWelcomeMessageAsync(turnContext, cancellationToken);
}
}
}
}
await _basicAccessors.ConversationState.SaveChangesAsync(turnContext, false, cancellationToken);
await _basicAccessors.UserState.SaveChangesAsync(turnContext, false, cancellationToken);
}
private async Task<bool> IsTurnInterruptedAsync(DialogContext dc, string topIntent)
{
// See if there are any conversation interrupts we need to handle.
if (topIntent.Equals(CancelIntent))
{
if (dc.ActiveDialog != null)
{
await dc.CancelAllDialogsAsync();
await dc.Context.SendActivityAsync("Ok. I've canceled our last activity.");
}
else
{
await dc.Context.SendActivityAsync("I don't have anything to cancel.");
}
return true; // Handled the interrupt.
}
if (topIntent.Equals(HelpIntent))
{
await dc.Context.SendActivityAsync("Let me try to provide some help.");
await dc.Context.SendActivityAsync("I understand greetings, being asked for help, or being asked to cancel what I am doing.");

{
await dc.RepromptDialogAsync();
}
return true; // Handled the interrupt.
}
这似乎是一个设计困境。我的建议是重新安排您的机器人的优先级,以便如果您的对话未正确响应,则仅调用Luis 。这可以通过将IsTurnInterruptedAsync
从OnTurnAsync
移至验证器方法来实现。可以将验证器方法作为参数传递给您提示的构造函数:
_dialogs.Add(new ConfirmPrompt(CONFIRMPROMPT, ValidateAsync));
,如果您的提示在其他类别中,则可以确保可以从任何地方访问最高意图。您可以通过在转弯状态中添加顶部意图来做到这一点,这是仅持续到单个转弯范围的状态。将此代码包括在OnTurnAsync
中:
var topScoringIntent = luisResults?.GetTopScoringIntent();
var topIntent = topScoringIntent.Value.intent;
// Include this:
turnContext.TurnState.Add("topIntent", topIntent);
您的ValidateAsync
方法看起来像这样:
private async Task<bool> ValidateAsync(PromptValidatorContext<bool> promptContext, CancellationToken cancellationToken)
{
if (promptContext.Recognized.Succeeded)
{
return true;
}
await IsTurnInterruptedAsync(promptContext.Context);
return false;
}
由于IsTurnInterruptedAsync
现在可能在另一个类中,因此需要通过您的转弯状态访问顶部意图。如果_dialogs
不在范围内,您也可以将其添加到轮回状态,或者将其作为公共/静态属性。
private async Task<bool> IsTurnInterruptedAsync(ITurnContext turnContext)
{
var dc = await _dialogs.CreateContextAsync(turnContext);
var topIntent = turnContext.TurnState.Get<string>("topIntent");
// See if there are any conversation interrupts we need to handle.
if (topIntent.Equals(CancelIntent))
{
// . . .
以这种方式,只有当话语对对话框无效时,才会发生中断。
即使说话对对话框有效,您可能要允许中断。当然,对于文本提示来说,任何有效的东西都是有效的,但是您仍然不想允许用户键入"我该怎么办?"作为他们的名字。如果您想先将话语发送到Luis进行某些类型的对话框,然后将话语发送到对话框中以获取其他类型的对话框,则可以检查堆栈顶部的对话框的类型:
var activeDialog = _dialogs.Find(dc.ActiveDialog.Id);
if (activeDialog is ConfirmPrompt || activeDialog is ChoicePrompt)
