Question

我正在开发Teams Message Extension，并且正在使用ThumbnailCard显示我的结果，但是我想使用自定义的自适应卡。那可能吗？

var resultCardList = GetAttachments(title);

var response = new ComposeExtensionResponse(new ComposeExtensionResult("list", "result"));
      response.ComposeExtension.Attachments = resultCardList.ToList();
      return response;

foreach (var contract in contractItems)
        {
          var lastModified = (DateTime)contract["Modified"];
          var justificativa = contract["JustificativaContrato"];
          var card = new ThumbnailCard
          {
            Title = $"{contract.Client_Title} - {lastModified.ToShortDateString()} {lastModified.ToLongTimeString()}",
            Text = $"Justificativa: {justificativa}",
            Tap = new CardAction { Type = "openUrl", Value = $"{Tenant}{ContractList.DefaultEditFormUrl}?ID={contract.Id}" },
            Images = new List<CardImage> { new CardImage("http://lorempixel.com/640/480?rand=" + DateTime.Now.Ticks.ToString()) }
          };

          cardList.Add(card
              .ToAttachment()
              .ToComposeExtensionAttachment());
        }

        return cardList;

我尝试使用以下方法来生成自适应卡并将其添加到列表中：

private static Microsoft.Bot.Connector.Attachment CreateAdaptiveCardAttachment()
    {
      // combine path for cross platform support
      string[] paths = { ".", "Cards", "welcomeCard.json" };
      string fullPath = Path.Combine(paths);
      var adaptiveCard = System.IO.File.ReadAllText(@"Cards\welcomeCard.json");
      return new Microsoft.Bot.Connector.Attachment()
      {
        ContentType = "application/vnd.microsoft.card.adaptive",
        Content = JsonConvert.DeserializeObject(adaptiveCard),
      };
    }

消息传递扩展名不允许发送类似的自适应卡。它要求使用框架的“ MessagingExtensionResult”，而仅使用响应中发送的卡。这里缺少文档。

当您从消息传递分机接到电话时，其操作的类型为“ composeExtension /查询”

像这样创建常规的“结果”列表：

var invokeResponse = new MessagingExtensionResponse();
var results = new MessagingExtensionResult
{
    AttachmentLayout = "list",
    Type = "result",
    Attachments = new List<MessagingExtensionAttachment>(),
};

对于列表中的每个结果，您需要创建一个MessagingExtensionAttachment，如下所示：（注意：卡片需要预览！）

results.Attachments.Add(new MessagingExtensionAttachment
{
    ContentType = "application/vnd.microsoft.teams.card.adaptive",
    Content = JsonConvert.DeserializeObject(cardData),
    Preview = new Attachment
    {
        ContentType = "application/vnd.microsoft.card.thumbnail",
        Content = new AttachmentContent
        {
            text = "Project: " + task.ProjectName,
            title = task.Name,
        },
    }
});

最后将结果发送为“ InvokeResponse”

            return new InvokeResponse
            {
                Body = invokeResponse,
                Status = 200,
            };

附件的“内容”是完整的自适应卡。您可以在json中找到响应示例： https://docs.microsoft.com/de-de/microsoftteams/platform/concepts/messaging-extensions/search-extensions#response-example

您可以基于此自由混合卡类型，但是据我所知，到目前为止我还没有得到有效的解决。据我所知，您现在需要限制为一种特定的卡类型。

以上全部是如果您使用的是 Microsoft.Bot.Builder.Teams

Microsoft.Bot.Connector.Teams

Microsoft.Bot.Schema.Teams

在最新版本中。

如何在Team Messaging Extension上使用自适应卡？
