botframework - 我如何使用 QnAMaker 为同一查询提供随机答案

Question

我在想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相同的答案。

或者还有像给我讲故事这样的问题

Answer 1

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.

要实现此要求，您可以尝试以下方法:

1) 添加 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，并在此方法中随机拆分响应并检索答案

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:
