无法将参数传递给 ContinueConversationAsync 方法内的 BotCallback

The*_*bot 2 c# asp.net-core botframework

我正在尝试在 bot 框架 v4 上实现主动消息，它可以工作，但只能使用 BotCallback 函数上的字符串，我需要传递自定义文本，但 ContinueConversationAsync 似乎不允许它

        public async Task<bool> SendProactiveMessage(MensajeExterno mensajeExterno)
    {

            var referenciaDeConversacion = ObtenerReferenciaConversacion(mensajeExterno.ConversationId);
            var continuationActivity = referenciaDeConversacion.GetContinuationActivity();
            if (referenciaDeConversacion == null) return false;


            await ((BotAdapter)_adapter).ContinueConversationAsync(_appId, referenciaDeConversacion, BotCallback, default(CancellationToken));

            return true;

    }

    private ConversationReference ObtenerReferenciaConversacion(string conversationId)
    {
        return new ConversationReferenceModulo().ObtenerConversationReference(conversationId);
    }

    public MensajeroDefaultModulo(IBotFrameworkHttpAdapter adapter, IConfiguration configuration)
    {
        _adapter = adapter;
        _appId = configuration["MicrosoftAppId"];

        if (string.IsNullOrEmpty(_appId))
        {
            _appId = Guid.NewGuid().ToString(); //if no AppId, use a random Guid
        }
    }

    private async Task BotCallback(ITurnContext turnContext, CancellationToken cancellationToken)
    {
        var activity = turnContext.Activity;
        await turnContext.SendActivityAsync("proactive hello", cancellationToken: cancellationToken);
    }

您可以使用 LINQ 方法对 BotCallback 进行包装。但我个人不理解没有任何 EventArgs 的代表的想法。

    [HttpPost]
    public async Task<IActionResult> Post([FromBody] string messageText)
    {
        foreach (var conversationReference in _conversationReferences.Values)
        {
            await ((BotAdapter)_adapter).ContinueConversationAsync(_appId, conversationReference, async (context, token) => await BotCallback(messageText, context, token), default(CancellationToken));
        }

        return new ContentResult()
        {
            Content = "<html><body><h1>Proactive messages have been sent.</h1></body></html>",
            ContentType = "text/html",
            StatusCode = (int)HttpStatusCode.OK,
        };
    }

    private async Task BotCallback(string message, ITurnContext turnContext, CancellationToken cancellationToken)
    {
        await turnContext.SendActivityAsync(message, cancellationToken: cancellationToken);
    }
