错误403禁止使用Youtube API V3

Question

我有Youtube Api v3的问题。问题是想要从上传的视频中获取信息，在执行视频的检索信息时，我收到错误403 Forbidden。

如果我运行网址，我使用浏览器返回Json me所有视频数据。

Visual Studio错误

浏览器中的相同网址。

 if (videoId != "")
            {

                // If the video has the same description as a video and uploaded to YouTube, then I have removed that was uploaded earlier and upload the newrequest.Service.QueryClientLoginToken();
                //Uri urlVideo = new Uri(String.Format("http://gdata.youtube.com/feeds/api/users/{0}/uploads/{1}", hipoConfig.canal_youtube, videoId)); This is This is the URL of the version 2.0
                Uri urlVideo = new Uri(String.Format("https://www.googleapis.com/youtube/v3/videos?id={0}&key={1}&part=snippet", videoId, hipoConfig.clave_api));

                Video ExistingVideo = request.Retrieve<Video>(urlVideo);
                log.escribirInfoLog("Informacion: El video " + ExistingVideo.VideoId + "se elimina de YouTube para ser sustituido");

                request.Delete(ExistingVideo);
