botframework - 如何使用 Bot Framework 版本 3 在 Skype 中显示音频和视频？

Question

我正在研究机器人框架技术，在我的一个项目中，我实现了一个概念，比如显示音频文件和视频文件，为此我必须在我的 MessagesController 中编写下面的代码行。

 ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));
    Activity replyToConversation = activity.CreateReply("Welcome to **Marriott Hotels**." + "(Hi)");
    replyToConversation.Recipient = activity.From;
        replyToConversation.Type = "message";
        //replyToConversation.AttachmentLayout = AttachmentLayouts.Carousel;
        replyToConversation.Attachments = new List<Attachment>();
      if (activity != null && activity.GetActivityType() == "message" && activity.Text.ToLower() == "video")
        {
            replyToConversation.Attachments.Add(new Attachment()
            {

                ContentUrl = "https://1drv.ms/v/s!At-JUB9_wu9Ct3LEMJtNj_ZP26r6",
                ContentType = "video/mp4",
                Name = "xxxxx hotel video"
            });
            var reply = await connector.Conversations.SendToConversationAsync(replyToConversation);
        }   
        else if (activity != null && activity.GetActivityType() == "message" && activity.Text.ToLower() == "file")
        {
            replyToConversation.Attachments.Add(new Attachment()
         {
             ContentUrl = "https://codeload.github.com/jeffhollan/BotFrameworkSample/zip/master",
                ContentType = "application/zip",
                Name = "Download ZIP File"
            });
            var reply = await connector.Conversations.SendToConversationAsync(replyToConversation);
        }

        else if (activity != null && activity.GetActivityType() == "message" && activity.Text.ToLower() == "audio")
                    {
                        replyToConversation.Attachments.Add(new Attachment()
        {
            //ContentUrl = "http://gaana.com/song/ulagam-oruvanukka",
            ContentUrl = "http://www.zzz.com/eatfood.wav",
                            ContentType = "audio/wav",
                            Name = "Play Audio" + "(Music)"
                        });
                        var reply = await connector.Conversations.SendToConversationAsync(replyToConversation);
                    }

添加代码并将我的应用程序发布到 azure 并添加 Skype 频道后，现在我开始与我的机器人聊天，然后显示视频提示，但是当我单击它没有播放它时，显示错误如下图所示。

请告诉我如何解决这个问题。普拉迪普
