Bot框架的模擬器中未顯示Hero Card

Question

我是Bot Framework的新手，我使用C＃編寫了一個簡單的漫游器，該漫游器應返回示例英雄卡作為回復。 問題在於，Hot卡未在Bot Framework通道仿真器中顯示。 這是代碼：

    public async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> arg)
    {
        var referenceMessage = await arg as IMessageActivity;
        var msg = (Activity)context.MakeMessage();
        Activity replyToConversation = msg.CreateReply($"Buscando resultados para {referenceMessage.Text}");
        replyToConversation.Recipient = msg.From;
        replyToConversation.Type = "message";
        replyToConversation.ReplyToId = referenceMessage.Id;
        replyToConversation.AttachmentLayout = "carousel";
        replyToConversation.Attachments = new List<Attachment>();
        List<CardImage> CardImages = new List<CardImage>();
        CardImages.Add(new CardImage()
        {
            Url = "https://upload.wikimedia.org/wikipedia/commons/thumb/b/be/BMW-Z4_diagonal_front_at_IAA_2005.jpg/243px-BMW-Z4_diagonal_front_at_IAA_2005.jpg"
        });

        CardAction btnWebsite = new CardAction()
        {
            Type = "openUrl",
            Title = "Open",
            Value = "http://bmw.com"
        };

        HeroCard plCard = new HeroCard()
        {
            Title = $"{referenceMessage.Text}",
            Subtitle = $"Resultados de busqueda para {referenceMessage.Text}",
            Images = CardImages,
            Tap = btnWebsite
        };

        var attachment = plCard.ToAttachment();
        replyToConversation.Attachments.Add(attachment);
        await context.PostAsync(replyToConversation);

        //var connector = new ConnectorClient(new Uri(msg.ServiceUrl));
        //var reply = connector.Conversations.SendToConversationAsync(replyToConversation);
    }

如您所見，我一直在嘗試使用上下文和連接器，但卡未顯示。我已經調試了應用程序，並且可以看到輸入信息已被正確捕獲

有什么想法嗎？

Answer 1

我將發布您可能的解決方案。

*如果您的函數在某些IDialog類中，並且如果您期望某些結果應如下所示：

private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> argument)

*第二個解決方案（如果我是您，我會用它）是從當前上下文創建一條消息。 所以你的代碼應該是：

 public async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> arg)
    {

        var replyToConversation= context.MakeMessage();

        replyToConversation.AttachmentLayout = "carousel";
        replyToConversation.Attachments = new List<Attachment>();
        List<CardImage> CardImages = new List<CardImage>();
        CardImages.Add(new CardImage()
        {
            Url = "https://upload.wikimedia.org/wikipedia/commons/thumb/b/be/BMW-Z4_diagonal_front_at_IAA_2005.jpg/243px-BMW-Z4_diagonal_front_at_IAA_2005.jpg"
        });

        CardAction btnWebsite = new CardAction()
        {
            Type = "openUrl",
            Title = "Open",
            Value = "http://bmw.com"
        };

        HeroCard plCard = new HeroCard()
        {
            Title = $"{referenceMessage.Text}",
            Subtitle = $"Resultados de busqueda para {referenceMessage.Text}",
            Images = CardImages,
            Tap = btnWebsite
        };

        var attachment = plCard.ToAttachment();
        replyToConversation.Attachments.Add(attachment);
        await context.PostAsync(replyToConversation);
    }

注意 ：

代替

replyToConversation.AttachmentLayout = "carousel",

采用

replyToConversation.AttachmentLayout =  AttachmentLayoutTypes.Carousel;

希望能幫助到你 ：）
