ماذا يحدث؟

BotBuilder.Community.Adapters.Alexa لا يبدو أنها تعمل مع VA.

ما هي خطوات إعادة إظهار هذه المشكلة؟

اتبع التعليمات هنا: - https://github.com/BotBuilderCommunity/botbuilder-community-dotnet/tree/develop/libraries/Bot.Builder.Community.Adapters.Alexa

1) في Startup.cs أضفت حزم NuGet التالية:

Bot.Builder.Community.Adapters.Alexa ؛
Bot.Builder.Community.Adapters.Alexa.Integration.AspNet.Core؛
Bot.Builder.Community.Adapters.Alexa.Middleware؛

قبل هذا الرمز

            // Configure bot
            services.AddTransient<IBot, DialogBot<MainDialog>>();

أضفت:

            // Registering the AlexaHttpAdapter
            services.AddSingleton<IAlexaHttpAdapter>((sp) =>
            {
                var alexaHttpAdapter = new AlexaHttpAdapter(validateRequests: true)
                {
                    OnTurnError = async (context, exception) =>
                    {
                        await context.SendActivityAsync("Sorry, something went wrong. Please try again later." + context + " Exception:" + exception);
                    },
                    ShouldEndSessionByDefault = true,
                    ConvertBotBuilderCardsToAlexaCards = false,
                };
                alexaHttpAdapter.Use(new AlexaIntentRequestToMessageActivityMiddleware());
                return alexaHttpAdapter;
            });

            services.AddSingleton<AlexaIntentRequestToMessageActivityMiddleware>();

2) إنشاء وحدة تحكم Alexa:

using Bot.Builder.Community.Adapters.Alexa.Integration.AspNet.Core;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Bot.Builder;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace GuideDogs_VA.Controllers
{
    [Route("api/skillrequests")]
    [ApiController]
    public class AlexaBotController : ControllerBase
    {
        private readonly IAlexaHttpAdapter _adapter;
        private readonly IBot _bot;

        public AlexaBotController(IAlexaHttpAdapter adapter, IBot bot)
        {
            _adapter = adapter;
            _bot = bot;
        }

        [HttpPost]
        public async Task PostAsync()
        {
            await _adapter.ProcessAsync(Request, Response, _bot);
        }
    }
}

3) إنشاء Alexa Skill باستخدام JSON التالي:

{
    "interactionModel": {
        "languageModel": {
            "invocationName": "guide dogs",
            "intents": [
                {
                    "name": "GetUserIntent",
                    "slots": [
                        {
                            "name": "phrase",
                            "type": "phrase"
                        }
                    ],
                    "samples": [
                        "{phrase}"
                    ]
                },
                {
                    "name": "AMAZON.FallbackIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.NavigateHomeIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.CancelIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.HelpIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.StopIntent",
                    "samples": []
                }
            ],
            "types": [
                {
                    "name": "phrase",
                    "values": [
                        {
                            "name": {
                                "value": "hi there Alexa"
                            }
                        },
                        {
                            "name": {
                                "value": "you are just going to repeat what I said aren't you"
                            }
                        },
                        {
                            "name": {
                                "value": "what colour is the sky?"
                            }
                        }
                    ]
                }
            ]
        }
    }
}

ماذا كنت تتوقع أن يحدث؟

عند اختبار Alexa Skill من خلال وحدة تحكم مطور Alexa أو عبر جهاز Alexa ، حتى تستجيب ، ولكن للأسف ينتهي الأمر بالاتصال بـ OnEventSync () على الرغم من أن نوع النشاط من نوع الرسالة.

هل يمكنك مشاركة أي سجلات أو ناتج خطأ وما إلى ذلك؟

System.NullReferenceException تم طرحه من ملف MainDialog.cs:

أي لقطات شاشة أو سياق إضافي؟

استجابة من VA إلى Alexa (استجابة تم إنشاؤها من سياق Startup.cs.SendActi vityAsync: - في انتظار السياق.
