2.根据阿里云视频配置录制成功回调，将返回的参数保存到数据库

3.观看重播时用数据库保存的视频名称地址去阿里云取newId和playauth

/// <summary>
    /// 获取视频地址
    /// </summary>
    /// <param name="client"></param>
    private string GetVideoPlayAuth(string videoId)
    {
        string accessKeyId = ConfigurationManager.AppSettings["ossKeyId"] ?? "";
        string accessKeySecret = ConfigurationManager.AppSettings["ossKeySecret"] ?? "";
        string endpoint = ConfigurationManager.AppSettings["endpoint"] ?? "";
        IClientProfile clientProfile = DefaultProfile.GetProfile("cn-shanghai", accessKeyId, accessKeySecret);
        DefaultAcsClient client = new DefaultAcsClient(clientProfile);
        GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();
        request.VideoId = videoId;
        GetVideoPlayAuthResponse response = client.GetAcsResponse(request);
        return JsonConvert.SerializeObject(response);
        //Console.WriteLine("RequestId = " + response.RequestId);
        //Console.WriteLine("PlayAuth = " + response.PlayAuth);
        //Console.WriteLine("Title = " + response.VideoMeta.Title);
        //Console.WriteLine("VideoId = " + response.VideoMeta.VideoId);
        //Console.WriteLine("CoverURL = " + response.VideoMeta.CoverURL);
        //Console.WriteLine("Duration = " + response.VideoMeta.Duration);
        //Console.WriteLine("Status = " + response.VideoMeta.Status);      
    }

播放器使用VideoId和PlayAuth就可以播放重播了
