如何在asp.net mvc (C#)中保存使用视频控件播放视频的进度？

<video id="videoPlayer" controls>
    <source src="video.mp4" type="video/mp4">
</video>

<script>
    var videoPlayer = document.getElementById("videoPlayer");
    videoPlayer.addEventListener("timeupdate", function() {
        var currentTime = videoPlayer.currentTime;
        // 发送当前播放时间到服务器
        $.ajax({
            url: "/Video/SaveProgress",
            type: "POST",
            data: { currentTime: currentTime },
            success: function(response) {
                // 处理保存成功的逻辑
            },
            error: function() {
                // 处理保存失败的逻辑
            }
        });
    });
</script>

[HttpPost]
public ActionResult SaveProgress(double currentTime)
{
    // 将播放时间保存到数据库或文件中
    // 例如，保存到数据库中的示例代码：
    using (var db = new ApplicationDbContext())
    {
        var progress = new VideoProgress
        {
            UserId = User.Identity.GetUserId(),
            VideoId = "video.mp4",
            Progress = currentTime
        };
        db.VideoProgresses.Add(progress);
        db.SaveChanges();
    }

    return Json(new { success = true });
}
