Botframework 模拟器和 404 错误

Question

我正在尝试编写一个使用 LUIS 的简单机器人，但似乎在更新后出现问题。

因此，在将 Botbuilder 更新到 1.1 之前，我遇到了无法找到 Luis.Models 的问题。升级后，解决一个coding error ，并删除 Microsoft.Bot.Connector.Utilities，我可以编译并成功运行，但无法通过模拟器连接。

这是我正在使用的代码。

using System;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Threading.Tasks;
using System.Web.Http;
using System.Web.Http.Description;
using System.Collections.Generic;
using Microsoft.Bot.Connector;
using Microsoft.Bot.Builder.Dialogs;
//using Microsoft.Bot.Connector.Utilities;
using Microsoft.Bot.Builder.Luis;
using Microsoft.Bot.Builder.Luis.Models;
using Newtonsoft.Json;

[LuisModel("c413b2ef-382c-45bd-8ff0-f76d60e2a821", "6d0966209c6e4f6b835ce34492f3e6d9")]
[Serializable]
public class Mybot : LuisDialog<object>
{

    [LuisIntent("")]
    public async Task None(IDialogContext context, LuisResult result)
    {
        string message = "I'm sorry I didn't understand. Try asking about your bill.";
        await context.PostAsync(message);
        context.Wait(MessageReceived);
    }

    [LuisIntent("NextInvoiceDate")]
    public async Task NextInvoiceDate(IDialogContext context, LuisResult result)
    {
        string message = "Your next payment will go out on the 17th of the month.";
        await context.PostAsync(message);
        context.Wait(MessageReceived);
    }

    [LuisIntent("NextAmount")]
    public async Task NextAmount(IDialogContext context, LuisResult result)
    {
        string message = $"Your next amount is expected to be around £29.72.";
        await context.PostAsync(message);
        context.Wait(MessageReceived);
    }
}

当我运行该项目时，它启动时没有错误，我得到的网页显示:

我的机器人在此处描述您的机器人以及您的使用条款等。访问 Bot Framework 以注册您的机器人。注册时，请记住将机器人的端点设置为 https://your_bots_hostname/api/messages

当我运行指向 https://localhost/api/messages 的模拟器时，它返回“发送请求时发生错误”。

JSON 在这里:

System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:443

   at System.Runtime.CompilerServices.ConfiguredTaskAwaitable`1.ConfiguredTaskAwaiter.GetResult()
   at Microsoft.Bot.Connector.Emulator.ConversationModel.<SendMessageAsync>d__50.MoveNext() 

我也只尝试过 HTTP(而不是 HTTPS)。

你能检查一下你是否为你的机器人使用了正确的 url 吗？检查项目属性中的项目 url 并确保使用正确的端口号。默认情况下，Bot Framework 项目模板使用 http://localhost :3978/
