Мне нужна помощь. Я новичок в разработке в Azure's Bot Framework и создании своего первого чат-бота несколько недель назад с использованием QnA KB. В любом случае мне удалось создать бота на портале Azure, и он работает отлично. Но мне нужно сделать некоторые изменения и тесты в Bot Framework Emulator (используя V4) и, для этого, загрузить и запустить мой бот локально.
Я загрузил .zip-файл моего бота, следуя инструкциям Azure, и инициализировал его, используя Visual Studio 2017 в качестве моей IDE. Когда я нажимаю кнопку «отладка», программа пытается подключиться к localhost: 3984 .
using Autofac;
using System.Web.Http;
using System.Configuration;
using System.Reflection;
using Microsoft.Bot.Builder.Azure;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Builder.Dialogs.Internals;
using Microsoft.Bot.Connector;
namespace SimpleEchoBot
{
public class WebApiApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
// Bot Storage: This is a great spot to register the private state storage for your bot.
// We provide adapters for Azure Table, CosmosDb, SQL Azure, or you can implement your own!
// For samples and documentation, see: https://github.com/Microsoft/BotBuilder-Azure
Conversation.UpdateContainer(
builder =>
{
builder.RegisterModule(new AzureModule(Assembly.GetExecutingAssembly()));
// Using Azure Table Storage
var store = new TableBotDataStore(ConfigurationManager.AppSettings["AzureWebJobsStorage"]); // requires Microsoft.BotBuilder.Azure Nuget package
// To use CosmosDb or InMemory storage instead of the default table storage, uncomment the corresponding line below
// var store = new DocumentDbBotDataStore("cosmos db uri", "cosmos db key"); // requires Microsoft.BotBuilder.Azure Nuget package
// var store = new InMemoryDataStore(); // volatile in-memory store
builder.Register(c => store)
.Keyed<IBotDataStore<BotData>>(AzureModule.Key_DataStore)
.AsSelf()
.SingleInstance();
});
GlobalConfiguration.Configure(WebApiConfig.Register);
}
}
}
Однако в считанные секунды следующая строка кода возвращает ошибку System.ArgumentNullException: «Значение не может быть нулевым.
Arg_ParamName_Name '
var store = new TableBotDataStore(ConfigurationManager.AppSettings["AzureWebJobsStorage"]); // requires Microsoft.BotBuilder.Azure Nuget package
Как следствие, я не могу проверить своего бота в эмуляторе Bot Framework. Поскольку я действительно новичок в C #, может кто-нибудь помочь мне решить эту проблему?
РЕДАКТИРОВАТЬ : Вот моя часть кода web.config, просто удаляющая конфиденциальные данные:
