我们如何在Microsoft bot框架中将用户消息和bot消息都记录到comos db

分类: 技术问答 • 2022-05-20 21:09:46
问题描述：

我已经使用Microsoft bot框架v4 sdk创建了一个聊天机器人.我想将机器人用户和机器人消息记录到cosmos db.

I have created a chat bot using microsoft bot framework v4 sdk. I wanted to log bot user and bot messages to cosmos db.

我只能使用下面的博客

i am able to log only user messages using below blog https://docs.microsoft.com/en-us/azure/bot-service/bot-builder-howto-v4-storage?view=azure-bot-service-4.0&tabs=csharp#using-cosmos-db .

我希望同时记录用户和漫游器的响应.

I expect to log both user and bot responses.

非常感谢，因为 TranscriptLoggerMiddleware 已经存在.

Thankfully, this is pretty easy since ItranscriptLogger and TranscriptLoggerMiddleware already exist.

using Microsoft.Bot.Builder;
using Microsoft.Bot.Builder.Azure;
using Microsoft.Bot.Schema;
using System.Collections.Generic;
using System.Threading;
using System.Threading.Tasks;

namespace QuickTestBot_CSharp
{
    public class CosmosTranscriptStore : ITranscriptLogger
    {
        private CosmosDbStorage _storage;

        public CosmosTranscriptStore(CosmosDbStorageOptions config)
        {
            _storage = new CosmosDbStorage(config);
        }
        public async Task LogActivityAsync(IActivity activity)
        {
            // activity only contains Text if this is a message
            var isMessage = activity.AsMessageActivity() != null ? true : false;
            if (isMessage)
            {
                // Customize this to save whatever data you want
                var data = new
                {
                    From = activity.From,
                    To = activity.Recipient,
                    Text = activity.AsMessageActivity().Text,
                };
                var document = new Dictionary<string, object>();
                // activity.Id is being used as the Cosmos Document Id
                document.Add(activity.Id, data);
                await _storage.WriteAsync(document, new CancellationToken());
            }
        }
    }
}

创建和添加中间件(在Startup.cs中)

[...]
var config = new CosmosDbStorageOptions
{
    AuthKey = "<YourAuthKey>",
    CollectionId = "<whateverYouWant>",
    CosmosDBEndpoint = new Uri("https://<YourEndpoint>.documents.azure.com:443"),
    DatabaseId = "<whateverYouWant>",
};

var transcriptMiddleware = new TranscriptLoggerMiddleware(new CosmosTranscriptStore(config));

var middleware = options.Middleware;
middleware.Add(transcriptMiddleware);
[...]

结果:

这可能是最简单/最佳的方法.但是，您也可以使用turnContext.OnSendActivities()捕获OnTurnAsync()下的传出活动，然后将传出活动也写入存储.

This is probably the easiest/best way to do it. However, you can also capture outgoing activities under OnTurnAsync() using turnContext.OnSendActivities() and then write the outgoing activity to storage, as well.
