我需要帮助，在迁移到新的 QNAMaker 后，我现在收到一个错误：未提供有效的 KnowledgeBaseId 和 SubscriptionKey。使用 QnAMakerServiceAttribute 或在 QnAMakerDialog 上设置字段。我错过了什么？订阅密钥和 KnowledgebaseID 已添加。在 qnamaker 门户中发布时，我只是按照示例 http 请求进行操作。

在此处输入图像描述

public class QnADialog : QnAMakerDialog<object>
{
   public async Task StartAsync(IDialogContext context)
    {
        context.PrivateConversationData.TryGetValue("Name", out name);
        await context.PostAsync($"Hello {name}. The QnA Dialog was started. Ask a question.");
        context.Wait(MessageReceivedAsync);

    }

    public async Task DefaultMatchHandler(IDialogContext context, string originalQueryText, QnAMakerResult result)
    {
        try
        {
            // ProcessResultAndCreateMessageActivity will remove any attachment markup from the results answer
            // and add any attachments to a new message activity with the message activity text set by default
            // to the answer property from the result
           // var messageActivity = ProcessResultAndCreateMessageActivity(context, ref result);
            if (result.Score > 30 && result.Answer != NOMATCH)
            {

                await context.Forward(new RootLuisDialog(), DialogsCompleted, context.Activity, CancellationToken.None);
            }
        }
        catch (Exception ex)

        }
        catch (Exception ex)

            throw;
        }

    }

    private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
    {
        var activity = await result as Activity;

        // calculate something for us to return
        int length = (activity.Text ?? string.Empty).Length;

        //if (!(bool)success)
        //    await context.PostAsync("I'm sorry. I didn't understand you.");

        //context.UserData.Clear();
        context.Wait(MessageReceived);
    }


    [QnAMakerResponseHandler(30)]
    public async Task LowScoreHandler(IDialogContext context, string originalQueryText, QnAMakerResult result)
    {
        //await context.PostAsync($"I found an answer that might help: {result.Answer}");
        await context.Forward(new RootLuisDialog(), DialogsCompleted, context.Activity, CancellationToken.None);
        //context.Wait(MessageReceived);
    }
}
}

调用 QNAMaker 的 RootDialog：

using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Builder.FormFlow;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Threading;
using System.Threading.Tasks;
using System.Web;

namespace Test.Dialog
{
[Serializable]
public class RootDialog : IDialog<object>
{
    public string name = string.Empty;
    public Task StartAsync(IDialogContext context)
    {
        context.Wait(MessageReceivedAsync);
        return Task.CompletedTask;
    }


     private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
    {
        try
       {
            //Some User Code that retreives user via PrivateConversationData




            //Calls QNADialog

            context.Call(new QnADialog(), MessageReceivedAsync);
       }
}

}

我的 CognitiveServices 版本：Microsoft.Bot.Builder.CognitiveServices.1.1.7 Bot Builder，Bot 连接器：3.15.2.2 QNADialog：1.2.0

正如通用公告中所解释的，您仍然可以Microsoft.Bot.Builder.CognitiveServices在代码中使用包：代码已更改为处理 bot v1 到 v3 调用和新的 v4（GA 版本）。

您只需添加必要的信息，即端点主机名，就像以前托管在 Microsoft 端一样。

因此，您的对话代码将如下所示（请参阅此处的 Github 官方示例）：

[Serializable]
[QnAMaker("set yout authorization key here", "set your kbid here", <score threshold>, <number of results>, "endpoint hostname")]
public class SimpleQnADialog : QnAMakerDialog
{
}

您似乎正在将QnAMakerDialog与 QnA Maker 服务 v4.0 一起使用，但在 NuGet 包QnAMakerDialog的描述和 QnAMakerDialog的 GitHub 自述文件（更新为与 QnA Maker v3 API 一起使用）中，我们可以发现这个 QnAMakerDialog 块包可以与 v3 一起使用QnA Maker API，而不是 QnA Maker 服务 v4.0。

如 Nicolas R 所说，要使用 QnA Maker 服务 v4.0，您可以使用此 NuGet 包：Microsoft.Bot.Builder.CognitiveServices来创建您的 QnAMakerDialog。

[Serializable]
public class QnADialog : QnAMakerDialog
{
    public QnADialog() : base(new QnAMakerService(new QnAMakerAttribute("{qnaAuthKey_here}", " {knowledgebaseId_here}", "No good match in FAQ.", 0.5, 1, "https://xxxx.azurewebsites.net/qnamaker")))
    { }

    //other code logic
}
