我正在使用Google的.net nuget(Google.Apis.YouTube.v3
)进行API调用。到目前为止,一切正常(获取播放列表,视频信息等)。
但是,当我尝试上传视频时,它会在几秒钟内完成,没有任何 react 。
从不调用upload_ResponseReceived
,并且仅两次调用upload_ProgressChanged
,并显示以下输出:
1)Bytes sent: 0, Status: Starting, Exception:
过了一会儿
2)Bytes sent: 0, Status: Failed, Exception: System.Threading.Tasks.TaskCanceledException: A task was canceled.

}
var youtubeService = new YouTubeService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = Assembly.GetExecutingAssembly().GetName().Name

var video = new Video();
video.Snippet = new VideoSnippet();

video.Status = new VideoStatus();
video.Status.PrivacyStatus = "unlisted"; // or "private" or "public"
var filePath = @"E:\video.mp4"; // Replace with path to actual movie file.
using (var fileStream = new FileStream(filePath, FileMode.Open))
{
var videosInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "video/*");
videosInsertRequest.ProgressChanged += videosInsertRequest_ProgressChanged;
videosInsertRequest.ResponseReceived += videosInsertRequest_ResponseReceived;
videosInsertRequest.Upload();
}
Console.ReadLine();
}

}
private static void videosInsertRequest_ProgressChanged(IUploadProgress obj)
{

知道我做错了什么吗?
最佳答案
好的,我认为您有连接问题,您所要做的就是将块大小更改为较小的大小,因此您的代码应如下所示:
