将 LUIS 与 c# 机器人框架集成 - 错误

Question

我正在尝试将 Luis.ai 集成到 C# 机器人框架中。代码运行但是当我向机器人发送消息时它显示此错误：

"sorry my bot code is having an issue"

当它应该根据使用意图的条目回复时，我只有 2 个意图 "None" 和 "perfil"。

这是我的日志：

这是我的 class Perfil.cs:

using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Builder.Luis;
using Microsoft.Bot.Builder.Luis.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Web;

namespace SistemaExperto.Dialogs
{
    [LuisModel(modelID: "e6168727-2f3e-438b-b46a-88449f4ab52f", subscriptionKey: "ed5f1bda20ac42649123b8969d30e1aa")]
    [Serializable]
    public class Perfil : LuisDialog<string>
    {

        [LuisIntent("None")]
        public async Task None(IDialogContext context, LuisServiceResult result)
        {
            await context.PostAsync("I'm sorry I don't have that information");
            await context.PostAsync("Try again");
        }

        [LuisIntent("perfil")]
        public async Task perfil(IDialogContext context, LuisServiceResult result)
        {
            await context.PostAsync("My name is Alex");
        }


    }
}

这是我的控制器MessageController.cs：

using System.Net;
using System.Net.Http;
using System.Threading.Tasks;
using System.Web.Http;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Connector;

namespace SistemaExperto
{
    [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 Dialogs.Perfil());
            }
            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;
        }
    }
}

我测试了您提供的代码并替换为我的 LUIS 应用 modelID 和 subscriptionKey，如果它达到 perfil 意图，代码将按预期工作。

如果 LuisDialog 无法根据收到的消息解析要执行的方法（意图），我会得到异常：

The given key was not present in the dictionary.

为了解决这个问题，我在 None 方法之上添加了 [LuisIntent("")]。

[LuisModel(modelID: "{your_modelID}", subscriptionKey: "{your_ subscriptionKey}")]
[Serializable]
public class Perfil : LuisDialog<object>
{
    [LuisIntent("")]
    [LuisIntent("None")]
    public async Task None(IDialogContext context, LuisResult result)
    {
        await context.PostAsync("I'm sorry I don't have that information");
        await context.PostAsync("Try again");
    }

    [LuisIntent("perfil")]
    public async Task perfil(IDialogContext context, LuisResult result)
    {
        await context.PostAsync("My name is Alex");
    }

}

测试结果：

达到 perfil 意图：
