Question

我正在使用Microsoft bot框架来创建机器人并使用直接渠道合并到Web应用程序中。在对话期间，我需要书签或喜欢来自机器人的消息或响应。

Answer 1

Bot Framework在SDK中没有实现这个功能。您可以利用中间件功能实现自己。

一般的想法是，您可以与用户一起保存每个活动消息对。并为mark或like创建global message handlers或检测中间件中的每封邮件，以检查用户是否mark或like。如果您可以为之前保存的最后一条消息标记mard标记。

有关中间件使用的示例，请参阅https://github.com/Microsoft/BotBuilder-Samples/tree/master/CSharp/core-Middleware了解C＃和https://github.com/Microsoft/BotBuilder-Samples/tree/master/Node/capability-middlewareLogging了解Node.js。

如有任何疑问，请随时告诉我。

实施 Microsoft.Bot.Builder.History 命名空间中的 IActivityLogger ，以将IMessageActivity消息存储/标记到数据库或缓存中。

IActivityLogger 将intercept来自您的对话框中实现IDialog接口的每条消息。

这是用于拦截从用户和机器人发送和接收的每条消息。

1）对于实现IDialog界面的对话框：

using Microsoft.Bot.Builder.History;
using Microsoft.Bot.Connector;
using MongoDB.Bson;
using MongoDB.Driver;
using System;
using System.Threading.Tasks;

namespace DemoBot.Dialogs
{
    public class Logger : IActivityLogger
    {

        private readonly IMongoClient client;
        private readonly IMongoCollection<BsonDocument> collection;
        public Logger()
        {
            client = new MongoClient();
            collection = client.GetDatabase("test").GetCollection<BsonDocument>("botLog");
        }
        public Task LogAsync(IActivity activity)
        {
            IMessageActivity msgToBeLogged = activity.AsMessageActivity();

            BsonDocument objectToBeLogged = new BsonDocument
            {
                { "messageText", new BsonString(msgToBeLogged.Text) },
                { "timeStamp", new BsonDateTime(Convert.ToDateTime(msgToBeLogged.Timestamp)) },
                { "recipientId", new BsonString(msgToBeLogged.Recipient.Id) },
                { "fromId", new BsonString(msgToBeLogged.From.Id) },
                { "conversationId", new BsonString(msgToBeLogged.Conversation.Id) },
                { "fromName", new BsonString(msgToBeLogged.From.Name) },
                { "toName", new BsonString(msgToBeLogged.Recipient.Name) },
                { "channnel", new BsonString(msgToBeLogged.ChannelId) },
                { "serviceUrl",new BsonString(msgToBeLogged.ServiceUrl) },
                { "locale", new BsonString(msgToBeLogged.Locale)}
            };

            return Task.Run(() =>
            {
                LogIntoDB(objectToBeLogged);
            });
        }

        public void LogIntoDB(BsonDocument activityDetails)
        {
            collection.InsertOne(activityDetails);
        }
    }
}

2）对于继承LuisDialog 类的Dialog，在DispatchToIntentHandler方法中编写日志代码，因为传入的消息将通过该方法解析为适当的处理程序：

using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Builder.Luis;
using Microsoft.Bot.Builder.Luis.Models;
using Microsoft.Bot.Connector;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace DemoBot.Dialogs
{
    [Serializable]
    public class RootDialog : LuisDialog<object>
    {
        public Task StartAsync(IDialogContext context)
        {
            return Task.Run(() => { context.Wait(MessageReceived); });
        }

        protected override Task DispatchToIntentHandler(IDialogContext context, IAwaitable<IMessageActivity> item, IntentRecommendation bestIntent, LuisResult result)
        {
            IMessageActivity msgToBeLogged = context.MakeMessage();

            BsonDocument objectToBeLogged = new BsonDocument
            {
                { "messageText", new BsonString(msgToBeLogged.Text) },
                { "timeStamp", new BsonDateTime(Convert.ToDateTime(msgToBeLogged.Timestamp)) },
                { "recipientId", new BsonString(msgToBeLogged.Recipient.Id) },
                { "fromId", new BsonString(msgToBeLogged.From.Id) },
                { "conversationId", new BsonString(msgToBeLogged.Conversation.Id) },
                { "fromName", new BsonString(msgToBeLogged.From.Name) },
                { "toName", new BsonString(msgToBeLogged.Recipient.Name) },
                { "channnel", new BsonString(msgToBeLogged.ChannelId) },
                { "serviceUrl",new BsonString(msgToBeLogged.ServiceUrl) },
                { "locale", new BsonString(msgToBeLogged.Locale)}
            };

            Task.Run(() =>
            {
                LogIntoDB(objectToBeLogged);
            });

            return base.DispatchToIntentHandler(context, item, bestIntent, result);
        }

        public void LogIntoDB(BsonDocument activityDetails)
        {
            collection.InsertOne(activityDetails);
        }


        public Task MessageReceived(IDialogContext context, IAwaitable<IMessageActivity> item)
        {
            return Task.Run(() =>
            {
                context.Wait(MessageReceived);
            });   
        }

    }
}

对于日志记录我正在使用MongoDB，但如果您愿意，也可以使用SQL Server。

最后使用Autofac IoC在global.asax.cs文件中注入依赖项。

using Autofac;
using DemoBot.Dialogs;
using Microsoft.Bot.Builder.Dialogs;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Routing;

namespace DemoBot
{
    public class WebApiApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            Conversation.UpdateContainer(builder =>
            {
                builder.RegisterType<Logger>().AsImplementedInterfaces().InstancePerDependency();
            });

            GlobalConfiguration.Configure(WebApiConfig.Register);
        }
    }
}
