我已经实现了首次启动QnA对话框的结构。如果QnA Dialog无法解决问题,那么它会启动一个Luis Dialog,它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。
我的问题是,当我尝试从QnAMaker启动LuisDialog时,它启动另一个LuisDialog进行对话,该对话框不会停止使用wait方法并在执行后立即自动调用ResumeAfter方法。
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);
}
}
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) {
}
}
第二届路易斯对话:
[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);
}
在执行转发后立即调用First Luis Dialog中的CallBackHandler方法。
答案 0 :(得分:0)
我认为这种行为是由于 QnAMakerDialog 在 DefaultWaitNextMessageAsync 方法中调用context.Done(true);
这一事实。参考:https://github.com/Microsoft/BotBuilder-CognitiveServices/blob/master/CSharp/Library/QnAMaker/QnAMaker/QnAMakerDialog.cs#L203
尝试改为覆盖 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);
}
}
