如何在 botbuilder-v3 上的特定条件下从 QnAMakerDialog（FAQ 类型聊天机器人）调用 formflow 对话框或普通对话框

Question

我的情况如下。

我是 Bot-framework 的新手，正在制作一个使用 KB 服务与 QnA-Maker 类型通信的聊天机器人，并根据返回的特定答案，尝试通过 FormFlow 调用或开始引导式对话。我正在使用 SDK-V3(C#.net) 和 QnAMakerDialog 。

是否可以在 botbuilder-v3 上的特定条件下从 QnAMakerDialog 调用表单流对话框？

谢谢

第一件事：如果您现在开始，您不应该使用 SDK-V3：使用 v4，它通常可以使用几个月。 v3 将不会在未来发展（除了几个补丁）。

然后，使用QnA Maker 查看 v4 的示例，这里：https://github.com/Microsoft/BotBuilder-Samples/blob/master/samples/csharp_dotnetcore/11.qnamaker/QnAMaker/QnABot.cs

在这个示例中，您可以看到您可以在QnABot.cs 中实现您的逻辑：

public async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default(CancellationToken))
{
    // Handle Message activity type, which is the main activity type for shown within a conversational interface
    // Message activities may contain text, speech, interactive cards, and binary or unknown attachments.
    // see https://aka.ms/about-bot-activity-message to learn more about the message and other activity types
    if (turnContext.Activity.Type == ActivityTypes.Message)
    {
        // Check QnA Maker model
        var response = await _services.QnAServices[QnAMakerKey].GetAnswersAsync(turnContext);
        if (response != null && response.Length > 0)
        {
            // PUT YOUR LOGIC HERE
            //await turnContext.SendActivityAsync(response[0].Answer, cancellationToken: cancellationToken);
        }
        else
        {
            var msg = @"No QnA Maker answers were found. This example uses a QnA Maker Knowledge Base that focuses on smart light bulbs. 
                To see QnA Maker in action, ask the bot questions like 'Why won't it turn on?' or 'I need help'.";

            await turnContext.SendActivityAsync(msg, cancellationToken: cancellationToken);
        }
    }
    else if (turnContext.Activity.Type == ActivityTypes.ConversationUpdate)
    {
        if (turnContext.Activity.MembersAdded != null)
        {
            // Send a welcome message to the user and tell them what actions they may perform to use this bot
            await SendWelcomeMessageAsync(turnContext, cancellationToken);
        }
    }
    else
    {
        await turnContext.SendActivityAsync($"{turnContext.Activity.Type} event detected", cancellationToken: cancellationToken);
    }
}
