我如何使用 QnAMaker 为同一查询提供随机答案

How can i use QnAMaker to provide random answers to same query

我在想,因为机器人有一些通用的问题,比如你好吗?可能我有大约 10 个答案,我希望问答制作者随机选择,而不是每次都选择相同的答案。

或者还有诸如给我讲个故事之类的问题

some generic questions like how are you ? may be i have around 10 answers which i would like Q&A maker to choose randomly not every time same answer.

要达到这个要求,可以试试这个方法:

1) 添加一个QnA对并使用特殊字符(例如|)拆分问题how are you?

的答案

2) 覆盖RespondFromQnAMakerResultAsync方法,并在该方法中拆分响应并随机检索答案

protected override async Task RespondFromQnAMakerResultAsync(IDialogContext context, IMessageActivity message, QnAMakerResults result)
{
    // This will only be called if Answers isn't empty

    var response = result.Answers.First().Answer;
    var answersforhowareyou = response.Split('|');

    if (answersforhowareyou.Count() > 1)
    {
        Random rnd = new Random();
        int index = rnd.Next(answersforhowareyou.Count());

        response = answersforhowareyou[index];
    }

    await context.PostAsync(response);
}

测试结果:
