Bot Framework と Microsoft Graph で DevOps その 13 : グローバルメッセージでダイアログを制御

※2017/6/10 テストについてやっぱり追記

今回はグローバルメッセージについて紹介します。

概要

ユーザーは開発者の意図通りに話してくれるか分からないという話は既にしました。途中でキャンセルしたいかもしれないし、急遽別のことを確認したいかもしれません。そのような場合は、特定のキーワードで現在の処理を中断したりキャンセルできるようにします。Bot Framework ではこのような処理またはキーワードをグローバルメッセージと呼んでいます。

処理のキャンセル

1. まずキャンセルのキーワードを登録。ボットアプリプロジェクトの Dialogs フォルダに、CancelScorable.cs を作成し、以下のコードと差し替えます。キーワードは多言語対応ということでリソースを使っています。

 using System;
using System.Threading;
using System.Threading.Tasks;
using Microsoft.Bot.Builder.Dialogs.Internals;
using Microsoft.Bot.Builder.Internals.Fibers;
using Microsoft.Bot.Connector;
using Microsoft.Bot.Builder.Scorables.Internals;
using O365Bot.Resources;

namespace O365Bot.Dialogs
{

#pragma warning disable 1998

    public class CancelScorable : ScorableBase<IActivity, string, double>
    {
        private readonly IDialogTask task;

        public CancelScorable(IDialogTask task)
        {
            SetField.NotNull(out this.task, nameof(task), task);
        }

        /// <summary>
        /// キーワードと比較して、一致すればキーワードを返す
        /// </summary>
        protected override async Task<string> PrepareAsync(IActivity activity, CancellationToken token)
        {
            var message = activity as IMessageActivity;

            if (message != null && !string.IsNullOrWhiteSpace(message.Text))
            {
                if (message.Text.Equals(O365BotLabel.Cancel, StringComparison.InvariantCultureIgnoreCase))
                {
                    return message.Text;
                }
            }

            return null;
        }

        protected override bool HasScore(IActivity item, string state)
        {
            return state != null;
        }

        protected override double GetScore(IActivity item, string state)
        {
            return 1.0;
        }

        /// <summary>
        /// キーワードがあった場合の処理。ここではタスクをキャンセル
        /// </summary>
        protected override async Task PostAsync(IActivity item, string state, CancellationToken token)
        {
            this.task.Reset();
        }

        protected override Task DoneAsync(IActivity item, string state, CancellationToken token)
        {
            return Task.CompletedTask;
        }
    }
}

2. 次にグローバルメッセージのハンドラーを登録。ボットアプリプロジェクトに GlobalMessageHandles.cs ファイルを追加し、コードを以下と差し替え。基本的にはここに Scorable を継承したクラスを登録していきます。

 using Autofac;
using O365Bot.Dialogs;
using Microsoft.Bot.Builder.Dialogs.Internals;
using Microsoft.Bot.Builder.Scorables;
using Microsoft.Bot.Connector;

namespace O365Bot.Handlers
{
    
    public class GlobalMessageHandlers : Module
    {
        protected override void Load(ContainerBuilder builder)
        {
            base.Load(builder);
            
            builder
                .Register(c => new CancelScorable(c.Resolve<IDialogTask>()))
                .As<IScorable<IActivity, double>>()
                .InstancePerLifetimeScope();
        }
    }
}

3. アプリ起動時に読み込まれるよう、Global.asax.cs を以下のコードに差し替え。以前 IoC 用に登録した際と異なり、BotBuilder がもともと持っている Container に情報をマージする形をとっています。

 using Autofac;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Builder.Internals.Fibers;
using O365Bot.Handlers;
using O365Bot.Services;
using System.Configuration;
using System.Web.Http;

namespace O365Bot
{
    public class WebApiApplication : System.Web.HttpApplication
    {
        public static IContainer Container;

        protected void Application_Start()
        {
            this.RegisterBotModules();
            GlobalConfiguration.Configure(WebApiConfig.Register);

            AuthBot.Models.AuthSettings.Mode = ConfigurationManager.AppSettings["ActiveDirectory.Mode"];
            AuthBot.Models.AuthSettings.EndpointUrl = ConfigurationManager.AppSettings["ActiveDirectory.EndpointUrl"];
            AuthBot.Models.AuthSettings.Tenant = ConfigurationManager.AppSettings["ActiveDirectory.Tenant"];
            AuthBot.Models.AuthSettings.RedirectUrl = ConfigurationManager.AppSettings["ActiveDirectory.RedirectUrl"];
            AuthBot.Models.AuthSettings.ClientId = ConfigurationManager.AppSettings["ActiveDirectory.ClientId"];
            AuthBot.Models.AuthSettings.ClientSecret = ConfigurationManager.AppSettings["ActiveDirectory.ClientSecret"];

            var builder = new ContainerBuilder();
            builder.RegisterType<GraphService>().As<IEventService>();
            Container = builder.Build();
        }
        
        private void RegisterBotModules()
        {
            var builder = new ContainerBuilder();
            builder.RegisterModule(new ReflectionSurrogateModule());
            builder.RegisterModule<GlobalMessageHandlers>();
            builder.Update(Conversation.Container);
        }
    }
}

意図した通りに動きます。興味があればデバッグして、どのように判定されているか見てください。

処理の割り込み

キャンセルではなく、処理を単に差し込見たい場合は、以下のようにします。

 1. Dialogs フォルダに GetEventsScorable.cs を追加して、コードを以下に差し替え。キャンセルとことなり、GetEventDialog を差し込んでいます。

using System;
using System.Threading;
using System.Threading.Tasks;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Builder.Dialogs.Internals;
using Microsoft.Bot.Builder.Internals.Fibers;
using Microsoft.Bot.Connector;
using Microsoft.Bot.Builder.Scorables.Internals;
using O365Bot.Resources;

namespace O365Bot.Dialogs
{
#pragma warning disable 1998

    public class GetEventsScorable : ScorableBase<IActivity, string, double>
    {
        private readonly IDialogTask task;

        public GetEventsScorable(IDialogTask task)
        {
            SetField.NotNull(out this.task, nameof(task), task);
        }

        protected override async Task<string> PrepareAsync(IActivity activity, CancellationToken token)
        {
            var message = activity as IMessageActivity;

            if (message != null && !string.IsNullOrWhiteSpace(message.Text))
            {
                if (message.Text.Equals(O365BotLabel.Get_Events, StringComparison.InvariantCultureIgnoreCase))
                {
                    return message.Text;
                }
            }

            return null;
        }

        protected override bool HasScore(IActivity item, string state)
        {
            return state != null;
        }

        protected override double GetScore(IActivity item, string state)
        {
            return 1.0;
        }

        /// <summary>
        /// キーワードが一致した際、処理を差し込み。
        /// </summary>
        protected override async Task PostAsync(IActivity item, string state, CancellationToken token)
        {
            var message = item as IMessageActivity;

            if (message != null)
            {
                var getEventsDialog = new GetEventsDialog();

                var interruption = getEventsDialog.Void<bool, IMessageActivity>();

                await this.task.Forward(interruption, null, message, CancellationToken.None);

                await this.task.PollAsync(token);
            }
        }

        protected override Task DoneAsync(IActivity item, string state, CancellationToken token)
        {
            return Task.CompletedTask;
        }
    }
}

2. GlobalMessageHandlers.cs の Load メソッドに以下コードを追加。

 builder
    .Register(c => new GetEventsScorable(c.Resolve<IDialogTask>()))
    .As<IScorable<IActivity, double>>()
    .InstancePerLifetimeScope();

エミュレーターで検証

イベント取得が差し込まれ、またイベント作成に戻っています。

テストの更新

ユニットテスト

ユニットテストでは、Global.asax.cs に登録した内容を含める必要があります。影響はすべてのテストにありますが、処理内容は同じです。以下のコードに UniteTest1.cs を入れ替えます。ポイントはグローバルメッセージの差し込み先の IContainer を間違えないことです。

ファンクションテスト

以下 2 つのテストを追加します。

 [TestMethod]
public void Function_ShouldCancelCurrrentDialog()
{
    DirectLineHelper helper = new DirectLineHelper(TestContext);
    var toUser = helper.SentMessage("add appointment");
    // 結果の検証
    Assert.IsTrue(toUser[0].Text.Equals(O365Bot_Models_OutlookEvent.message0_LIST));
    Assert.IsTrue(toUser[1].Text.Equals(O365Bot_Models_OutlookEvent.Subject_promptDefinition_LIST));

    toUser = helper.SentMessage("件名");
    Assert.IsTrue(toUser[0].Text.Equals(O365Bot_Models_OutlookEvent.Description_promptDefinition_LIST));

    toUser = helper.SentMessage(O365BotLabel.Cancel);
    Assert.IsTrue(toUser.Count.Equals(0));

    toUser = helper.SentMessage("add appointment");
    Assert.IsTrue(toUser[0].Text.Equals(O365Bot_Models_OutlookEvent.message0_LIST));
    Assert.IsTrue(toUser[1].Text.Equals(O365Bot_Models_OutlookEvent.Subject_promptDefinition_LIST));
}

まとめ

結構簡単にグローバルメッセージを組み込めました。これでメニューに関連するキーワード来たら処理をやり直しなど、柔軟な対応ができますね。次回はボットからプロアクティブに話しかけるシナリオを紹介します。
