用户在对话框列表中选择 "None of the Above" 选项后，如何创建流程？

Question

我试图在用户选择 "None of the above" 后创建一个进程。

如您所知，当用户输入模糊消息时，QnA Maker 会回复相关的多个问题列表。在列表的底部，我们可以看到 "None of the above".

我想在用户选择 "None of the above" 框后创建一个进程。我已经尝试覆盖 BasicQnAMakerDialog()，但做不到。

如果有人知道怎么做，请告诉我。

Answer 1

I would like to create a process after the user selects "None of the above" box.

您可以尝试覆盖DefaultWaitNextMessageAsync方法并检测用户select "None of the above"选项，以下代码片段供您参考。

protected override async Task DefaultWaitNextMessageAsync(IDialogContext context, IMessageActivity message, QnAMakerResults result)
{
    if (message.Text.Equals("None of the above."))
    {
        // your code logic

        await context.PostAsync("You selected 'None of the above.'");
    }

    await base.DefaultWaitNextMessageAsync(context, message, result);
}

测试结果：

更新：

"What kind of thing do you want to ask?" -> user inputs "blah blah blah"

您可以在 DefaultWaitNextMessageAsync 方法中向用户发送“您想问什么样的事情？”，并等待用户输入。

完整示例代码：

namespace Microsoft.Bot.Sample.QnABot
{
    [Serializable]
    public class RootDialog : IDialog<object>
    {
        public async Task StartAsync(IDialogContext context)
        {
            /* Wait until the first message is received from the conversation and call MessageReceviedAsync 
            *  to process that message. */
            context.Wait(this.MessageReceivedAsync);
        }

        private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
        {
            /* When MessageReceivedAsync is called, it's passed an IAwaitable<IMessageActivity>. To get the message,
             *  await the result. */
            var message = await result;

            context.ConversationData.SetValue<bool>("isnotdefaultmes", false);

            var qnaAuthKey = GetSetting("QnAAuthKey");
            //var qnaKBId = Utils.GetAppSetting("QnAKnowledgebaseId");
            var qnaKBId = ConfigurationManager.AppSettings["QnAKnowledgebaseId"];
            var endpointHostName = ConfigurationManager.AppSettings["QnAEndpointHostName"];

            // QnA Subscription Key and KnowledgeBase Id null verification
            if (!string.IsNullOrEmpty(qnaAuthKey) && !string.IsNullOrEmpty(qnaKBId))
            {
                // Forward to the appropriate Dialog based on whether the endpoint hostname is present
                if (string.IsNullOrEmpty(endpointHostName))
                    await context.Forward(new BasicQnAMakerPreviewDialog(), AfterAnswerAsync, message, CancellationToken.None);
                else
                    await context.Forward(new BasicQnAMakerDialog(), AfterAnswerAsync, message, CancellationToken.None);
            }
            else
            {
                await context.PostAsync("Please set QnAKnowledgebaseId, QnAAuthKey and QnAEndpointHostName (if applicable) in App Settings. Learn how to get them at https://aka.ms/qnaabssetup.");
            }

        }

        private async Task AfterAnswerAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
        {
            // wait for the next user message
            context.Wait(MessageReceivedAsync);
        }

        public static string GetSetting(string key)
        {
            //var value = Utils.GetAppSetting(key);
            var value = ConfigurationManager.AppSettings[key];

            if (String.IsNullOrEmpty(value) && key == "QnAAuthKey")
            {
                //value = Utils.GetAppSetting("QnASubscriptionKey"); // QnASubscriptionKey for backward compatibility with QnAMaker (Preview)
                value = ConfigurationManager.AppSettings["QnASubscriptionKey"];
            }
            return value;
