Youtube comments API引发“权限不足：请求的身份验证范围不足”错误

Question

我试图获取Youtube评论，但它抛出了这个异常 -

｛“Google.api.Requests.RequestError\r\n权限不足：请求的身份验证作用域不足。[403]\r\nErrors[\r\n\tMessage[权限不足：申请的身份验证范围不足。]位置[-]原因：[UnficificientPermissions]域[全局]\r\r\m\n”｝

凭证源代码-

UserCredential credsDataApi = GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                new[] { YouTubeService.Scope.YoutubeForceSsl, YouTubeService.Scope.Youtubepartner, YouTubeAnalyticsService.Scope.YtAnalyticsReadonly, YouTubeAnalyticsService.Scope.YtAnalyticsMonetaryReadonly, YouTubeAnalyticsService.Scope.Youtube, "https://www.googleapis.com/auth/plus.login" },

                "user",
                CancellationToken.None,
                new FileDataStore(Directory.GetCurrentDirectory() + "\\MetadataAccessToken\\" + channelinfo.DataAPIFileDataStore, true)
                ).Result; 

这是它抛出异常的行-

UserCredential credsDataApi = YouTubeHelper.GetUserCredentialForDataAPI(channelinfo);
            var youtubeServiceComments = new YouTubeService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credsDataApi,
                ApplicationName = channelinfo.DataAPIFileDataStore
            });

var searchCommentThreadlistRequest=youtubeServiceComments.CommentThreals。列表（“片段”）；var searchCommentThreadlistResponse=searchCommentThreadlistRequest。ExecuteAsync（）；如果（searchCommentThreadlistResponse.Result.Items.Count）

你能帮忙吗？
