Операция вернула недопустимый код состояния «MethodNotAllowed» - эмулятор Bot Framework

Question

У меня есть дизайн бота с моделью потока формы. Когда я выполняю это локально в эмуляторе бота. Выдает ошибку.

Исключение: Операция вернула недопустимый код состояния 'MethodNotAllowed'

Я не могу запустить мой в настоящее время разработанный бот, ни предыдущий протестированный и бегущие боты. У меня проблема с Bot Emulator? или какая-либо версия не совпадает между BotFrameworks?

Я использую VS 2015 и BotFramework V3. На моем компьютере также установлена ​​VS 2019.

Answer 1

MethodNotAllowed код ошибки означает, что вы используете неправильный метод HTTP, например, вызываете конечную точку с POST, когда она разрешает только GET или DELETE

Answer 2

После долгого исследования комментария, данного @Alexander, я обнаружил, что этот блог Государственная служба ботов скоро выйдет на пенсию 31 марта 2018 года . после просмотра содержимого, которое я обнаружил, нам нужно сохранить состояние в базе данных или в локальной памяти. Поэтому я добавил код в Global.asax файл, который решает мою проблему.

protected void Application_Start()
    {
        Conversation.UpdateContainer(
        builder =>
        {
            builder.RegisterModule(new AzureModule(Assembly.GetExecutingAssembly()));
            // Bot Storage: register state storage for your bot
            // Default store: volatile in-memory store - Only for prototyping!
            // var store = new InMemoryDataStore();
            // This sample will use Azure Table Storage 
            //var store = new TableBotDataStore(ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString);
            var store = new InMemoryDataStore();
            builder.Register(c => store)
                .Keyed<IBotDataStore<BotData>>(AzureModule.Key_DataStore)
                .AsSelf()
                .SingleInstance();
        });

        GlobalConfiguration.Configure(WebApiConfig.Register);
    }
