c# - 如何让机器人根据意图响应正确答案

Question

这个问题已经有答案了:

How to use LUIS None Intent in c# without train utterance at LUIS (1 个回答)

已关闭 6 年前。

我正在使用 luis.ai 和 botframework:

我的问题是，当我尝试发送消息(不属于话语的一部分，因此未知输入时，我没有收到消息:$“抱歉，我不明白'{result.Query}'。请再试一次”; ...但每次都会出现欢迎消息，来自问候意图。

我不知道为什么会发生这种情况。请你帮助我好吗 ？

这是我的代码:MessagController.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 FirstBotApplication
   {
//[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 AllTheBot());
        }
        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;
    }
   }
 }

        await context.PostAsync(message);

        context.Wait(this.MessageReceived);

}

        await context.PostAsync("Do you want to test our bot ? We suggest to type : hi or who are you, help etc..");
        context.Wait(MessageReceived);
    }

    public async Task thankyou(IDialogContext context, IAwaitable<IMessageActivity> activity, LuisResult result)
    {
        await context.PostAsync("I want to thank you for your time.");
        context.Wait(MessageReceived);
    }



    [LuisIntent("exit")]
        [LuisIntent("Utilities.Stop")]
    public async Task exit(IDialogContext context, IAwaitable<IMessageActivity> activity, LuisResult result)
    {
        await context.PostAsync("Thank you for your time ! You are welcome again here :) ");
        context.Wait(MessageReceived);
    }




}

您的 None 方法未使用“None”和 Empty 意图进行修饰。更新您的方法，使其如下所示:

[LuisIntent("None")]
[LuisIntent("")]
public async Task None(IDialogContext context, LuisResult result)
{
    string message = $"Sorry, I did not understand '{result.Query}'. Please try again";

    await context.PostAsync(message);

    context.Wait(this.MessageReceived);
 }
