如何使用C#在瀑布对话框上调用QnA Maker?

问题描述

我正在尝试在瀑布对话框步骤中呼叫 QnA Maker .

如何在此 watterfall 步骤中调用它，我是否需要设置QnA?在瀑布步骤中，我是否需要从中调用 QnA ?LUIS意图，我该怎么办?

How do I call it from this watterfall step, do I need to set up QnA On the waterfall step, do I need to call QnA from a LUIS intent, what can I do?

我需要它使用上一个问题的步骤上下文从QnA中获得第一个结果.

I need it to get the first result from the QnA using the step context from the previous question.

任何人都可以帮忙吗?

代码:

private async Task<DialogTurnResult> QnaAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{
    var response = await qnaMaker.GetAnswersAsync(stepContext);

    // use answer found in qnaResults[0].answer
    return await stepContext.PromptAsync(nameof(TextPrompt), new PromptOptions { Prompt = MessageFactory.Text(response[0].Answer)}, cancellationToken);
}

推荐答案

似乎您的上面的代码中没有定义 qnaMaker .只要您在某处定义了QnAMaker服务，您就可以真正从任何地方调用QnAMaker.

It looks like you don't have qnaMaker defined in your code above, there. You can really call QnAMaker from anywhere, so long as you have a QnAMaker service defined somewhere.

我建议遵循此示例.它相当复杂，但却是在瀑布对话框中使用QnAMaker的最佳示例.

I recommend following this sample. It's fairly complex, but is the best example of using QnAMaker within a Waterfall Dialog.

我将指出一些您会发现最有用的部分:

I'll point out some pieces that you will find most useful:

1. 创建QnAMaker服务
2. 使用依赖注入，以便您可以从项目中的任何位置访问BotServices
3. 将服务添加到对话框的构造函数中
4. 致电QnAMaker服务

1. Create the QnAMaker service
2. Use dependency injection so that you can access the BotServices from anywhere in the project
3. Add the services to the dialog's constructor
4. Call the QnAMaker service

同样，该样本相当复杂.如果您需要其他指针，请使用您尝试的代码更新您的问题，我会帮助您.

Again, that sample is fairly complex. If you need additional pointers, please update your question with the code that you've tried and I'll see if I can help.
