MS Bot 将对话数据保存到 Cosmos DB

Question

我已成功将我的 MS Bot 连接到 Azure Cosmos DB。默认情况下，IBotDataStore 不保存对话文本。我已经通过context.ConversationData.SetValue("message", messageText); 为每个PostAsync 找到了一种方法。谁能帮助我更好地做到这一点？

Global.asax.cs

    var uri = new Uri(ConfigurationManager.AppSettings["DocumentDbUrl"]);
    var key = ConfigurationManager.AppSettings["DocumentDbKey"];
    var store = new DocumentDbBotDataStore(uri, key);

    Conversation.UpdateContainer(
                builder =>
                {
                    builder.Register(c => store)
                        .Keyed<IBotDataStore<BotData>>(AzureModule.Key_DataStore)
                        .AsSelf()
                        .SingleInstance();
                    builder.Register(c => new CachingBotDataStore(store, CachingBotDataStoreConsistencyPolicy.ETagBasedConsistency))
                        .As<IBotDataStore<BotData>>()
                        .AsSelf()
                        .InstancePerLifetimeScope();
                });

        public async Task StartAsync(IDialogContext context)
        {
            messageText  = "Hi, can I please have your name.";
            await context.PostAsync(messageText);
            context.ConversationData.SetValue("message", messageText);
            context.Wait(GetName);
        }

        public virtual async Task GetName(IDialogContext context, IAwaitable<IMessageActivity> result)
        {
            var _result = await result;
            userName = _result.Text;
            //string message = activity.AsMessageActivity()?.Text;

            context.UserData.SetValue("username", userName);

            messageText = $"Thanks {userName}, how can I help you?";
            await context.PostAsync(messageText);
            context.ConversationData.SetValue("message", messageText);
            context.Done(context);
        }
    }
}

您检查过 IActivityLogger 界面吗？ https://docs.microsoft.com/en-us/azure/bot-service/dotnet/bot-builder-dotnet-middleware 实现此接口将使您能够将对话历史记录保存在您选择的任何消息存储中。

IBotDataStore 不是用于对话历史记录，而是用于 UserData、ConversationData 和 PrivateConversationData 状态。
