Botframework V4：如何發送視頻附件？

Question

很抱歉，這看起來像是一個輕松的問題，但我真的在任何地方都找不到。 文檔中也沒有示例。 互聯網上關於botframework v4的指南也很少。 有人可以給我提供視頻卡或視頻英雄卡或輪播形式的視頻英雄卡的示例嗎？ 謝謝！

日冰！

Bot Framework示例存儲庫的C＃部分中有一個示例，稱為“ 06. Using Cards” 。 如果您運行此示例，它將顯示在通道允許的情況下bot框架可以執行的所有卡的示例。 在示例中，您可以選擇“全部顯示”以查看輪播中的卡片，其中一張卡片是視頻卡。

private static VideoCard GetVideoCard()
    {
        var videoCard = new VideoCard
        {
            Title = "Big Buck Bunny",
            Subtitle = "by the Blender Institute",
            Text = "Big Buck Bunny (code-named Peach) is a short computer-animated comedy film by the Blender Institute," +
                   " part of the Blender Foundation. Like the foundation's previous film Elephants Dream," +
                   " the film was made using Blender, a free software application for animation made by the same foundation." +
                   " It was released as an open-source film under Creative Commons License Attribution 3.0.",
            Image = new ThumbnailUrl
            {
                Url = "https://upload.wikimedia.org/wikipedia/commons/thumb/c/c5/Big_buck_bunny_poster_big.jpg/220px-Big_buck_bunny_poster_big.jpg",
            },
            Media = new List<MediaUrl>
            {
                new MediaUrl()
                {
                    Url = "http://download.blender.org/peach/bigbuckbunny_movies/BigBuckBunny_320x180.mp4",
                },
            },
            Buttons = new List<CardAction>
            {
                new CardAction()
                {
                    Title = "Learn More",
                    Type = ActionTypes.OpenUrl,
                    Value = "https://peach.blender.org/",
                },
            },
        };

        return videoCard;
    }
