LUIS/Bot Framework多个对话框，将意图处理移至另一个对话框 [英] LUIS / Bot Framework multiple dialog, move intent handling to another dialog

问题描述

我的目标是使用C#SDK将对话框和LUIS都实现到Microsoft Bot Framework应用程序中. 我尝试遵循此线程 https://github.com/Microsoft /BotBuilder/issues/127 及其相关文章(最后引用)，但无法使我的代码在实践中起作用.这是我的RootDialog类.请注意，我创建了一个处理"GetProduct"意图的方法，当它获得此意图时，应使用context.Forward()方法将LuisResult转发到ProductsDialog，但是我看到的只是直接进入了ResumeAfter方法. ，ProductsDialogCompleted.现在，这可能是我失败的地方，但是我找不到显示多个LUIS对话框的示例.

my goal is to implement both dialogs and LUIS into a Microsoft Bot Framework application using their C# SDK. I tried to follow this thread https://github.com/Microsoft/BotBuilder/issues/127 and their related posts (referenced at the end) but couldn't get my code working in practice. This is my RootDialog class. Note that I created a method which handles the "GetProduct" intent, when it gets this intent, it should forward the LuisResult to ProductsDialog using context.Forward() method, but instead what I see is just that it goes straight to the ResumeAfter method, ProductsDialogCompleted. Now, here is probably where I fail but I couldn't find an example showing multiple LUIS dialogs.

public class RootDialog : LuisDialog<object>
{
    [LuisIntent("GetProduct")]
    private async Task GetProduct(IDialogContext context, LuisResult result)
    {
        await context.PostAsync("Calling ProductsDialog...");
        await context.Forward(Chain.From(() => new ProductsDialog()), ProductsDialogCompleted, context.Activity, CancellationToken.None);
    }

    private async Task ProductsDialogCompleted(IDialogContext context, IAwaitable<object> result)
    {
        var res = await result;
        context.PostAsync("ProductsDialogCompleted" + result);
        context.Wait(this.MessageReceived);
    }
}
public class ProductsDialog : LuisDialog<object>
{
    public async Task StartAsync(IDialogContext context)
    {
        await context.PostAsync("Entered ProductsDialog");

        context.Wait(this.MessageReceived);
    }
    [LuisIntent("None")]
    private async Task None(IDialogContext context, LuisResult result)
    {
        context.Done(true);
    }
}

预期的行为如下

1. 用户触发GetProduct意图
2. 机器人创建了一个新对话框，并转到StartAsync方法，在此方法中它等待其他用户输入
3. 用户触发无"意图
4. 对话框关闭，返回true，并触发ProductsDialogCompleted.

似乎我没有正确绑定对话框.我该如何解决?

It seems like I'm not correctly binding the dialogs. How can I solve this?

添加了MessageController，版本为3.8.1

Added MessageController, version is 3.8.1

[BotAuthentication]
public class MessagesController : ApiController
{
    /// <summary>
    /// POST: api/Messages
    /// Receive a message from a user and reply to it
    /// </summary>
    public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
    {
        if (activity.Type == ActivityTypes.Message)
        {
            await Conversation.SendAsync(activity, () => new RootDialog());
        }
        else
        {
            HandleSystemMessage(activity);
        }
        var response = Request.CreateResponse(HttpStatusCode.OK);
        return response;
    }

    private Activity HandleSystemMessage(Activity message)
    {
        if (message.Type == ActivityTypes.DeleteUserData)
        {
            // Implement user deletion here
            // If we handle user deletion, return a real message
        }
        else if (message.Type == ActivityTypes.ConversationUpdate)
        {
            // Handle conversation state changes, like members being added and removed
            // Use Activity.MembersAdded and Activity.MembersRemoved and Activity.Action for info
            // Not available in all channels
        }
        else if (message.Type == ActivityTypes.ContactRelationUpdate)
        {
            // Handle add/remove from contact lists
            // Activity.From + Activity.Action represent what happened
        }
        else if (message.Type == ActivityTypes.Typing)
        {
            // Handle knowing tha the user is typing
        }
        else if (message.Type == ActivityTypes.Ping)
        {
        }

        return null;
    }
}

推荐答案

尝试从context.Forward调用中删除Chain.From(().不知道为什么要添加它，但根本不应该添加它.

Try removing the Chain.From(() from the context.Forward call. Not sure why you are adding it, but it shouldn't be there at all.

尝试:

await context.Forward(new ProductsDialog(), ProductsDialogCompleted, context.Activity, CancellationToken.None);

并且顺便说一句，如果您转发的消息符合None意图，则由于您正在执行context.Done，这将终止ProductsDialogCompleted方法，这基本上结束了ProductsDialog.

And btw, if the message you forward hits the None intent the ProductsDialogCompleted method will be hit because you are doing context.Done, which basically ends the ProductsDialog.

此外，请记住StartAsync方法存在于LuisDialog<T>基类中，因此您需要添加override关键字.

Also, have in mind the StartAsync method is present in the LuisDialog<T> base class, so you need to add the override keyword.
