将自适应卡片组合框的结果传递给另一种方法

Question

我正在使用自适应卡片组合框来显示某些类别的产品。一旦用户点击该类别，该类别应传递给另一个方法，并在另一个自适应卡片组合框中显示该类别的所有产品，并让用户 select 一个产品。

这是将所有类别获取到组合框的代码。

    public async Task GetCategoryAdaptiveCard(IDialogContext context)
    {
        var replyToConversation = context.MakeMessage();
        replyToConversation.Attachments = new List<Attachment>();

        HttpResponseMessage response = new HttpResponseMessage();
        string query = string.Format(APIChatBot + "/AllCategory");

        using (var client = ClientHelper.GetClient())
        {
            response = await client.GetAsync(query);
        }
        var categoryList = await response.Content.ReadAsAsync<IEnumerable<CategoryDTO>>();
        AdaptiveCard adaptiveCard = new AdaptiveCard();
        adaptiveCard.Speak = "Please Select A Category from the list";

        adaptiveCard.Body.Add(new TextBlock()
        {
            Text = "Please Select A Category from the list",
            Size = TextSize.Normal,
            Weight = TextWeight.Normal
        });

        adaptiveCard.Body.Add(new TextBlock()
        {
            Text = "Category List",
            Size = TextSize.Normal,
            Weight = TextWeight.Normal
        });

        List<AdaptiveCards.Choice> list = new List<AdaptiveCards.Choice>();

        foreach (var item in categoryList)
        {
            AdaptiveCards.Choice choice = new AdaptiveCards.Choice()
            {
                Title = item.CategoryName,
                Value = item.Id.ToString()
            };

            list.Add(choice);
        }
        adaptiveCard.Body.Add(new ChoiceSet()
        {
            Id = "Category",
            Style = ChoiceInputStyle.Compact,
            Choices = list
        });

        Attachment attachment = new Attachment()
        {
            ContentType = AdaptiveCard.ContentType,
            Content = adaptiveCard
        };

        replyToConversation.Attachments.Add(attachment);
        await context.PostAsync(replyToConversation);
    }

这是我用来获取 selected 类别产品的方法。

   public async Task GetProductForCategory(IDialogContext context, string category)
    {
        var replyToConversation = context.MakeMessage();
        replyToConversation.Attachments = new List<Attachment>();

        HttpResponseMessage response = new HttpResponseMessage();
        string query = string.Format(APIChatBot + "/ProductByCategory/" + category);

        using (var client = ClientHelper.GetClient())
        {
            response = await client.GetAsync(query);
        }

        var productList = await response.Content.ReadAsAsync<IEnumerable<ProductDTO>>();

        if(productList .Count() == 0)
        {
            string message = "Sorry There Are No products For this Category" + category;
           await context.PostAsync(message);
        }
        else
        {
            List<AdaptiveCards.Choice> list = new List<AdaptiveCards.Choice>();

            foreach (var item in productList )
            {
                AdaptiveCards.Choice choice = new AdaptiveCards.Choice()
                {
                    Title = item.ProductName,
                    Value = item.Id.ToString()
                };

                list.Add(choice);
            }

            AdaptiveCard adaptiveCard = new AdaptiveCard();
            adaptiveCard.Body.Add(new TextBlock()
            {
                Text = "List of Products for the Category " + category,
                Size = TextSize.Normal,
                Weight = TextWeight.Normal
            });

            adaptiveCard.Body.Add(new TextBlock()
            {
                Text = "Please Select A Product From The List",
                Size = TextSize.Normal,
                Weight = TextWeight.Normal
            });

            adaptiveCard.Body.Add(new ChoiceSet()
            {
                Id = "ProductForCategory",
                Style = ChoiceInputStyle.Compact,
                Choices = list
            });

            Attachment attachment = new Attachment()
            {
                ContentType = AdaptiveCard.ContentType,
                Content = adaptiveCard
            };

            replyToConversation.Attachments.Add(attachment);
            await context.PostAsync(replyToConversation);
        }
    }

如何将用户 select 的类别传递给 select 基于类别的产品的方法？

Answer 1

如果您创建这样的自适应卡：

var reply = context.MakeMessage();
var card = new AdaptiveCard();

var choices = new List<Choice>();
choices.Add(new Choice()
{
    Title = "Category 1",
    Value = "c1"
});
choices.Add(new Choice()
{
    Title = "Category 2",
    Value = "c2"                       
});
var choiceSet = new ChoiceSet()
{
    IsMultiSelect = false,
    Choices = choices,
    Style = ChoiceInputStyle.Compact,
    Id = "Category"
};
card.Body.Add(choiceSet);
card.Actions.Add(new SubmitAction() { Title = "Select Category", Data = Newtonsoft.Json.Linq.JObject.FromObject(new { button = "select" }) });

reply.Attachments.Add(new Attachment()
{
    Content = card,
    ContentType = AdaptiveCard.ContentType, 
    Name = $"Card"
});

await context.PostAsync(reply);

当用户选择其中一个选项并单击按钮时，生成的 activity 的值将是一个作业对象，您可以反序列化并用于创建产品特定的自适应卡：

class CategorySelection
{
    public string Category { get; set; }
}

var activityValue = activity.Value as Newtonsoft.Json.Linq.JObject;
if (activityValue != null)
{
    var categorySelection = activityValue.ToObject<CategorySelection>();
    var category = categorySelection.Category;
    //query the database for products of this category type, 
    //create another adaptive card displaying the products and send to user

    await context.PostAsync(reply);
}
