我有3个对话框,有 InitialDialog , StepOneDialog ,最后是 EndDialog 。每个Dialog通过执行以下操作来调用它的子:
await context.Forward(dialog, ResumeAfter, new Activity { }, CancellationToken.None);
这在本地完美运行,但是当我发布它时会出现问题。它只是陷入循环中,我认为这是因为Dialog没有正确退出。 InitialDialog 继承 LuisDialog 。 我有一个方法的代码:
[LuisIntent("")]
public async Task None(IDialogContext context, LuisResult result)
{
// Create our response
var response = $"Sorry I did not understand your question.";
// Post our response back to the user
await context.PostAsync(response);
// Exit the application
context.Done(this);
}
如您所见,我调用context.Done(this)
退出对话框,但我不确定这是否正确。在其他示例中,他们似乎使用context.Wait(MessageReceived);
我的其他对话框实现IDialog<object>
,因此我无法调用 MessageReceived 。所以在这种情况下,我设置了一个这样的方法:
private async Task ResumeAfter(IDialogContext context, IAwaitable<object> result) => context.Done(this);
我这样调用:
private async Task GetAnswer(IDialogContext context, IAwaitable<string> result)
{
// Get our quest
var questions = _group.Questions;
var length = questions.Count;
var question = _group.Questions[_currentQuestion];
var selectedAnswer = await result;
// Assign our answer to our question
foreach (var answer in question.Answers)
if (answer.Text == selectedAnswer)
question.Answer = answer;
// If we have an answer, filter the products
if (question.Answer != null)
_productProvider.Score(await GetCurrentProducts(), _groups);
// Increase our index
_currentQuestion++;
// If our current index is greater or equal than the length of the questions
if (_currentQuestion == length)
{
// Create our dialog
var dialog = _dialogFactory.CreateSecondStepDialog(_dialogFactory, _groupProvider, _questionProvider, _productProvider, await GetCurrentProducts());
// Otherwise, got to the next step
await context.Forward(dialog, ResumeAfter, new Activity { }, CancellationToken.None);
return;
}
// Ask our next question
await AskQuestion(context, null);
}
如您所见,context.Forward
将方法作为Delegate传递,并在创建子对话框后执行。
有人可以告诉我,如果我这样做吗?或者,如果我需要改变一些东西。

如果从当前对话框转发到Luis对话框消息,您可以使用:
var _message = context.MakeMessage();
_message.Text = "Custom user query";
await context.Forward(new MyRootLuisDialog(), MyRootLuisDialogComplete, _message);
如果打开Luis(子)对话框,您可以使用:
context.Call(new MyRootLuisDialog(), MyRootLuisDialogComplete);
回调示例:
public virtual async Task MyRootLuisDialogComplete(IDialogContext context, IAwaitable<object> response)
{
var _response = (MyDialogData)await response;
...
}
子对话框退出:
...
context.Done(_dialogData); // type of _dialogData is MyDialogData
...
