Это образец документации Botframework v4. Но это не работает.
На эмуляторе бота Microsoft написано "Can't Render Card".
То, что я пытаюсь сделать, это карусельная карта, но эта простая карта из образца Microsoft уже не работает.
{
"type": "message",
"text": "Plain text is ok, but sometimes I long for more...",
"attachments": [
{
"contentType": "application/vnd.microsoft.card.adaptive",
"content": {
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"type": "AdaptiveCard",
"version": "1.0",
"body": [
{
"type": "TextBlock",
"text": "Hello World!",
"size": "large"
},
{
"type": "TextBlock",
"text": "*Sincerely yours,*"
},
{
"type": "TextBlock",
"text": "Adaptive Cards",
"separation": "none"
}
],
"actions": [
{
"type": "Action.OpenUrl",
"url": "http://adaptivecards.io",
"title": "Learn More"
}
]
}
}
]
}
Однако, если я удаляю верхнюю часть кода, этот код работает:
{
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"type": "AdaptiveCard",
"version": "1.0",
"body": [
{
"type": "TextBlock",
"text": "Hello World!",
"size": "large"
},
{
"type": "TextBlock",
"text": "*Sincerely yours,*"
},
{
"type": "TextBlock",
"text": "Adaptive Cards",
"separation": "none"
}
],
"actions": [
{
"type": "Action.OpenUrl",
"url": "http://adaptivecards.io",
"title": "Learn More"
}
]
}
Вот как я называю карточку. Есть ли лучший способ сделать это?
public class GetNameAndAgeDialog : WaterfallDialog
{
private readonly string _cards = @".\Resources\TryCarouselCard.json";
private static Attachment CreateAdaptiveCardAttachment(string filePath)
{
var adaptiveCardJson = File.ReadAllText(filePath);
var adaptiveCardAttachment = new Attachment()
{
ContentType = "application/vnd.microsoft.card.adaptive",
Content = JsonConvert.DeserializeObject(adaptiveCardJson),
};
return adaptiveCardAttachment;
}
public GetNameAndAgeDialog(string dialogId, IEnumerable<WaterfallStep> steps = null) : base(dialogId, steps)
{
AddStep(async (stepContext, cancellationToken) =>
{
var cardAttachment = CreateAdaptiveCardAttachment(_cards);
var reply = stepContext.Context.Activity.CreateReply();
reply.Attachments = new List<Attachment>() { cardAttachment };
await stepContext.Context.SendActivityAsync(reply, cancellationToken);
return await stepContext.ContinueDialogAsync();
});
}
}
