已经调用ResumeAfter方法，而无需在下一个对话框中调用context.done

问题描述

我实现了一个首先启动QnA对话框的结构.如果QnA对话框无法解决问题，则它将启动Luis对话框，该对话框已定义了一些主要功能.基于这些主要功能，我启动了可以解决问题的特定对话框.

I have implemented a structure where a QnA dialog is first started. If the QnA Dialog cannot solve the problem then it starts a Luis Dialog which has some main functionalities defined. Based on those main functionalities I start specific dialogs that can solve the problem.

我的问题是，当我尝试从QnAMaker启动LuisDialog时，它会启动另一个LuisDialog进行对话，该对话框不会在使用wait方法时停止，并在执行后立即自动调用ResumeAfter方法.

My problem is that when I try to start LuisDialog from QnAMaker, it starts another LuisDialog to for conversation, That dialog doesn't stop on with wait method and automatically calls ResumeAfter method immediately after executing.

QnADialog:

QnADialog:

protected override async Task RespondFromQnAMakerResultAsync(IDialogContext context, IMessageActivity message, QnAMakerResults results)
{
    if (results == null || results.Answers.Count==0 || !IsConfidentAnswer(results) || results.Answers.FirstOrDefault().Score<0.75) {
        await context.Forward(new MainLuisDialog(), MessageReceived, context.Activity.AsMessageActivity(), CancellationToken.None);

    }
}

第一个Luis对话框:

First Luis Dialog:

[LuisIntent(ErrorFileLink)]
public async Task ErrorFileLinkIntentHandler(IDialogContext context, LuisResult result) {
    await context.Forward(new ErrorFileLinkDialog(), CallBackHandler, context.Activity.AsMessageActivity(), CancellationToken.None);
}

private async Task CallBackHandler(IDialogContext context, IAwaitable<object> result)
{
    try {
        var returnedResult = await result;
        if (returnedResult as string == "done")
            context.Done(false);
    }
    catch (Exception e) {
    }
}

第二个路易斯对话框:

[LuisIntent(MainAppIntent)]
public async Task MainAppIntentHandler(IDialogContext context, LuisResult result)
{
    if(context.GetPrivateConversationData<SyncIssueStates>(CurrentDialogState) == SyncIssueStates.ExpectingSyncCompleteMessage)
    {
        await context.PostAsync(Utility.GetResourceString("SYNC_ISSUE_PLEASE_WAIT_SYNC_COMPELTE"));
        context.Wait(MessageReceived);
        return;
    }
    await context.PostAsync(Utility.GetResourceString("SYNC_ISSUE_GET_ERROR_MESSAGE"));
    context.SetPrivateConversationData(CurrentDialogState, SyncIssueStates.ExpectingErrorMessage);
    context.Wait(MessageReceived);
}

执行前进"后立即调用第一个Luis对话框"中的CallBackHandler方法.

CallBackHandler Method in First Luis Dialog is called right after Forward is executed.

推荐答案

我认为此行为是由于 QnAMakerDialog 在 DefaultWaitNextMessageAsync 内部调用context.Done(true);造成的方法.参考: https://github.com/Microsoft/BotBuilder-CognitiveServices/blob/master/CSharp/Library/QnAMaker/QnAMaker/QnAMakerDialog.cs#L203

I think this behavior is due to the fact that the QnAMakerDialog calls context.Done(true); inside the DefaultWaitNextMessageAsync method. ref: https://github.com/Microsoft/BotBuilder-CognitiveServices/blob/master/CSharp/Library/QnAMaker/QnAMaker/QnAMakerDialog.cs#L203

尝试改写 DefaultWaitNextMessageAsync 方法:

protected override async Task DefaultWaitNextMessageAsync(IDialogContext context, IMessageActivity message, QnAMakerResults results)
{
    if (results == null || results.Answers.Count == 0 || !IsConfidentAnswer(results) || results.Answers.FirstOrDefault().Score < 0.75)
    {
        await context.Forward(new FirstDialog(), AfterForward, context.Activity.AsMessageActivity(), CancellationToken.None);
        context.Wait(base.MessageReceivedAsync);
    }
    else
    {
        await base.DefaultWaitNextMessageAsync(context, message, results);
    }
}
