如何在 IDialog 上下文中使用 ThumbnailCard
How to use the ThumbnailCard in IDialog Context
您好,我正在使用 Microsoft botframework
项目开发一个机器人,因为我正在使用 IDialog
界面。因为我使用 ThumbnailCard
来显示卡片。在这里,当我将一些数据附加到我的卡片上并且数据附加正确时,但在 PostAsync
方法中它没有提供回复。
public virtual async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> argument)
{
ThumbnailCard plCard = null;
IMessageActivity replyToConversation =await argument;
replyToConversation.Type = "message";
replyToConversation.Attachments = new List<Attachment>();
replyToConversation.Text = "welcome to book my show";
Dictionary<string, string> cardContentList = new Dictionary<string, string>();
cardContentList.Add("Jason Bourne", "URL");
cardContentList.Add("The Land", "URL");
cardContentList.Add("Yoga Hosers", "URL");
foreach (KeyValuePair<string, string> cardContent in cardContentList)
{
List<CardImage> cardImages = new List<CardImage>();
cardImages.Add(new CardImage(url: cardContent.Value));
List<CardAction> cardButtons = new List<CardAction>();
if (cardContent.Key == "Jason Bourne")
{
CardAction plButton1 = new CardAction()
{
Value = $"",
Type = "openUrl",
Title = "Book Now"
};
CardAction plButton2 = new CardAction()
{
Value = "tel:1-800-800-5705",
Type = "call",
Title = "Show timings"
};
cardButtons.Add(plButton1);
cardButtons.Add(plButton2);
plCard = new ThumbnailCard()
{
Title = $"Jason Bourne",
Subtitle = " ",
Images = cardImages,
Buttons = cardButtons,
};
Attachment plAttachment = plCard.ToAttachment();
replyToConversation.Attachments.Add(plAttachment);
}
else if (cardContent.Key == "The Land")
{
CardAction plButton1 = new CardAction()
{
Value = $"",
Type = "openUrl",
Title = "Book Now"
};
CardAction plButton2 = new CardAction()
{
Value = "tel:1-800-800-5705",
Type = "call",
Title = "Show Timings"
};
cardButtons.Add(plButton1);
cardButtons.Add(plButton2);
plCard = new ThumbnailCard()
{
Title = $"The Land",
Subtitle = "",
Images = cardImages,
Buttons = cardButtons,
};
Attachment plAttachment = plCard.ToAttachment();
replyToConversation.Attachments.Add(plAttachment);
}
else if (cardContent.Key == "Yoga Hosers")
{
CardAction plButton1 = new CardAction()
{
Value = $"",
Type = "openUrl",
Title = "Book Now"
};
CardAction plButton2 = new CardAction()
{
Value = "tel:1-800-800-5705",
Type = "call",
Title = "Show timings"
};
cardButtons.Add(plButton1);
cardButtons.Add(plButton2);
plCard = new ThumbnailCard()
{
Title = $"Yoga Hosers",
Subtitle = "",
Images = cardImages,
Buttons = cardButtons,
};
Attachment plAttachment = plCard.ToAttachment();
replyToConversation.Attachments.Add(plAttachment);
}
}
replyToConversation.AttachmentLayout = AttachmentLayoutTypes.List;
await context.PostAsync(replyToConversation);
}
当我 运行 机器人显示以下错误
我们可以在 IDialog 上下文 中使用卡片作为附件吗?
问题出在 IMessageActivity 上,您正试图在 context.PostAsync 中发送 IMessageActivity。这就是它失败的原因。
进行以下更改以使其工作
像下面这样更改方法签名
private async Task messageReceived(IDialogContext context, IAwaitable<object> argument)
并将IMessageActivity replyToConversation =await argument;
修改为喜欢下面
var message = await argument as Activity;
Activity replyToConversation = message.CreateReply("Welcome." + "(Hi)");
replyToConversation.Recipient = message.From;
现在应该可以了,如果还有问题请在这里评论。
