我想使用 ITranscriptLogger 和 TranscriptMiddelWare 将整个聊天历史记录存储在 cosmos DB 中，但我很难做到这一点。我读过了这篇 MS 文章，但我想将其存储在 Cosmos DB 中而不是 Blob 存储中。另外，我正在尝试在 Startup.cs 中而不是在 Bot.cs 中实例化转录日志，并且我尝试根据这个答案没有任何运气。也就是说，不会存储脚本，并且我的 Azure cosmos DB 中没有容器。我感谢任何帮助和反馈。
Code:
我已经创建了 TranscriptStore 类，并按照引用的 SO 答案中的说明创建并添加了中间件：
CosmosTranscriptStore.cs
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());
}
}
}
启动.cs
public class Startup
{
private const string CosmosServiceEndpoint = "MyCosmosServiceEndpoint";
private const string CosmosDBKey = "MyCosmosDBKey";
private const string CosmosDBDatabaseName = "MyCosmosDBDatabaseName";
private const string CosmosDBCollectionName = "Transcript-storage";
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public void ConfigureServices(IServiceCollection services)
{
var config = new CosmosDbStorageOptions
{
AuthKey = CosmosDBKey,
CollectionId = CosmosDBCollectionName,
CosmosDBEndpoint = new Uri(CosmosServiceEndpoint),
DatabaseId = CosmosDBDatabaseName,
};
var transcriptMiddleware = new TranscriptLoggerMiddleware(new CosmosTranscriptStore(config));
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
// Create the Bot Framework Adapter.
services.AddSingleton<IBotFrameworkHttpAdapter, AdapterWithErrorHandler>();
// Create the bot as a transient. In this case the ASP Controller is expecting an IBot.
services.AddSingleton<MainDialog>();
services.AddTransient<IBot, WelcomeBot<MainDialog>>();
services.AddBot<WelcomeBot<MainDialog>>(options =>
{
var middleware = options.Middleware;
middleware.Add(transcriptMiddleware);
});
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseHsts();
}
app.UseDefaultFiles();
app.UseStaticFiles();
app.UseMvc();
}
}
}
我设法通过将转录本存储中间件添加到适配器来解决这个问题，在提出这个问题之前我可能应该从一开始就这样做，但我对机器人框架和这种类型的编程都很陌生。
这就是我解决它的方法：
启动.cs
public void ConfigureServices(IServiceCollection services)
{
...
var config = new CosmosDbStorageOptions
{
AuthKey = CosmosDBKey,
CollectionId = CosmosDBAntoherCollectionName,
CosmosDBEndpoint = new Uri(CosmosServiceEndpoint),
DatabaseId = CosmosDBDatabaseName,
};
var transcriptMiddleware = new TranscriptLoggerMiddleware(new CosmosTranscriptStore(config));
services.AddSingleton(transcriptMiddleware);
...
}
AdapterWithErrorHandler.cs
public class AdapterWithErrorHandler : BotFrameworkHttpAdapter
{
public AdapterWithErrorHandler(TranscriptLoggerMiddleware transcriptMiddlewareStore, IConfiguration configuration, ILogger<BotFrameworkHttpAdapter> logger, ConversationState conversationState = null)
: base(configuration, logger)
{
Use(transcriptMiddlewareStore);
OnTurnError = async (turnContext, exception) =>
{
...
};
}
}
此外，如果想要将整个聊天记录存储在一个文档/项目中，我强烈建议通过对话 ID 而不是活动 ID 将数据存储在 CosmosTranscriptStore 类中。原因是每个活动都有自己的 ID，从而在 Cosmos DB 中为每个活动创建一个新项目。
public class CosmosTranscriptStore : ITranscriptLogger
{
...
public async Task LogActivityAsync(IActivity activity)
{
...
document.Add(activity.Conversation.Id, data);
await chatStorage.WriteAsync(document, new CancellationToken());
}
}
