Carousel Card在Facebook Messenger的BotFramework中效果不佳

Question

我已经实施了一个机器人，它会向用户发送一张英雄卡作为回应。 正如我所料，以下代码将一个轮播发送给信使。

ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));

#region HeroCard
Activity replyToConversation = activity.CreateReply("Should go to conversation, with a hero card");
replyToConversation.Recipient = activity.From;
replyToConversation.Type = "message";
replyToConversation.Attachments = new List<Attachment>();
List<CardImage> cardImages = new List<CardImage>();
cardImages.Add(new CardImage(url: "https://upload.wikimedia.org/wikipedia/en/a/a6/Bender_Rodriguez.png"));
cardImages.Add(new CardImage(url: "https://upload.wikimedia.org/wikipedia/en/archive/a/a9/20151112035044!Banyan_Tree_(_Shiv_Bajrang_Dham_Kishunpur).jpeg"));
List<CardAction> cardButtons = new List<CardAction>();
CardAction plButton = new CardAction()
{
    Value = "https://en.wikipedia.org/wiki/Pig_Latin",
    Type = "openUrl",
    Title = "WikiPedia Page"
};
CardAction plButton2 = new CardAction()
{
    Value = "https://en.wikipedia.org/wiki/Pig_Latin",
    Type = "openUrl",
    Title = "WikiPedia Page"
};
cardButtons.Add(plButton);
cardButtons.Add(plButton2);
HeroCard plCard = new HeroCard()
{
    Title = "I'm a hero card",
    Subtitle = "Pig Latin Wikipedia Page",
    Images = cardImages,
    Buttons = cardButtons
};
Attachment plAttachment = plCard.ToAttachment();
replyToConversation.Attachments.Add(plAttachment);
var reply = await connector.Conversations.SendToConversationAsync(replyToConversation);
#endregion

但是，我收到的信息不是旋转木马。

问题是如何使用botframework的本机变量（不使用手动生成的json）向Facebook Messenger发送轮播？

Answer 1

这些变化解决了这个问题：

• 首先，创建两张卡片和附件
• 其次，将AttachmentLayout设为"carousel"。

您可以在以下内容中找到修改后的代码：

ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));

#region HeroCard

Activity replyToConversation = activity.CreateReply("Should go to conversation, with a hero card");
replyToConversation.Recipient = activity.From;
replyToConversation.Type = "message";
replyToConversation.Attachments = new List<Attachment>();
// First Change
// Card #One
List<CardImage> cardImages1 = new List<CardImage>();
cardImages1.Add(new CardImage(url: "https://upload.wikimedia.org/wikipedia/en/a/a6/Bender_Rodriguez.png"));

List<CardAction> cardButtons1 = new List<CardAction>();
CardAction plButton1 = new CardAction()
{
    Value = "https://en.wikipedia.org/wiki/Pig_Latin",
    Type = "openUrl",
    Title = "WikiPedia Page"
};
cardButtons1.Add(plButton1);
HeroCard plCard1 = new HeroCard()
{
    Title = "I'm a hero card",
    Subtitle = "Pig Latin Wikipedia Page",
    Images = cardImages1,
    Buttons = cardButtons1
};
Attachment plAttachment1 = plCard1.ToAttachment();
replyToConversation.Attachments.Add(plAttachment1);

// Card #Two
List<CardImage> cardImages2 = new List<CardImage>();
cardImages2.Add(new CardImage(url: "https://upload.wikimedia.org/wikipedia/en/archive/a/a9/20151112035044!Banyan_Tree_(_Shiv_Bajrang_Dham_Kishunpur).jpeg"));

List<CardAction> cardButtons2 = new List<CardAction>();
CardAction plButton2 = new CardAction()
{
    Value = "https://en.wikipedia.org/wiki/Pig_Latin",
    Type = "openUrl",
    Title = "WikiPedia Page"
};
cardButtons2.Add(plButton2);
HeroCard plCard2 = new HeroCard()
{
    Title = "I'm a hero card",
    Subtitle = "Pig Latin Wikipedia Page",
    Images = cardImages2,
    Buttons = cardButtons2
};

Attachment plAttachment2 = plCard2.ToAttachment();
replyToConversation.Attachments.Add(plAttachment2);

// Second Change
replyToConversation.AttachmentLayout = "carousel";

var reply = await connector.Conversations.SendToConversationAsync(replyToConversation);
#endregion
