当我用确认提示或是或否提示提示用户时你好。路易斯正在检测“否”作为取消意图，取消了我的整个对话。然后我从取消意图中删除了“否”但现在“没有被luis检测为问候意图。问候意图中甚至没有”没有“字。尽可能我不想禁用luis因为用户可以随时取消。我该如何解决这个问题？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();
break;
default:
await dc.CancelAllDialogsAsync();
break;
}
}
}
else if (activity.Type == ActivityTypes.ConversationUpdate)
{
if (activity.MembersAdded != null)
{
// Iterate over all new members added to the conversation.
foreach (var member in activity.MembersAdded)
{
// Greet anyone that was not the target (recipient) of this message.
// To learn more about Adaptive Cards, see https://aka.ms/msbot-adaptivecards for more details.
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.");
if (dc.ActiveDialog != null)
{
await dc.RepromptDialogAsync();
}
return true; // Handled the interrupt.
}
这似乎是一种设计困境。我的建议是重新安排机器人的优先级，这样只有在对话框没有得到正确响应时才会调用LUIS。这可以通过将IsTurnInterruptedAsync从OnTurnAsync移动到验证器方法来实现。验证器方法可以作为参数传递给提示符的构造函数：
_dialogs.Add(new ConfirmPrompt(CONFIRMPROMPT, ValidateAsync));
您需要确保可以从任何地方访问您的顶级意图，以防您的提示位于不同的类中。您可以通过将最高意图添加到转弯状态来执行此操作，这是仅持续一转的范围的状态。在OnTurnAsync中包含此代码：
var topScoringIntent = luisResults?.GetTopScoringIntent();
var topIntent = topScoringIntent.Value.intent;
// Include this:
turnContext.TurnState.Add("topIntent", topIntent);
你的ValidateAsync方法可能如下所示：
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现在可能属于不同的类，因此需要通过转弯状态访问最高意图。如果_dialogs超出范围，您可以将其添加到转弯状态，或者只是将其设为公共/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))
{
// . . .
这样，只有当话语对对话无效时才会发生中断。
即使话语对对话有效，您也可能希望允许中断。当然，任何内容都适用于文本提示，但您仍然可能不希望允许用户输入“我该怎么办？”作为他们的名字。如果您想首先将话语发送到LUIS以获取某些类型的对话框，并将话语首先发送到对话框以用于其他类型的对话框，您可以检查堆栈顶部的对话框类型，如下所示：
var activeDialog = _dialogs.Find(dc.ActiveDialog.Id);
if (activeDialog is ConfirmPrompt || activeDialog is ChoicePrompt)
