Question

我正在尝试为频道列表和第一页编译频道统计信息，但是当我使用令牌调用下一页时，它给我一个错误，即URI字符串太长。

我正在使用.NET Core 2.2和Google.Apis.YouTube.v2 V1.39.0.1572。我使用的代码非常简单：

var youtubeService = new YouTubeService(new BaseClientService.Initializer()
                {
                    ApiKey = Startup.Configuration["YTConfigurations:ApiKey"],
                    ApplicationName = this.GetType().ToString()
                });

                ChannelsResource.ListRequest channelsListRequest = youtubeService.Channels.List("snippet,statistics,brandingSettings,topicDetails");
                channelsListRequest.Id = string.Join(",", channelEntities.Select(v => v.YTChannelId));

                channelsListRequest.MaxResults = 50;

                do
                {
                    pageCounter++;
                    channelListResponse = channelsListRequest.Execute();//here is the error after page 1

                    foreach (var listResult in channelListResponse.Items)
                    {
                        channelEntity = channelEntities.FirstOrDefault(v => v.YTChannelId == listResult.Id);
                        channelEntity = Mapper.Map(listResult, channelEntity);   
                        _repository.UpdateChannel(channelEntity);
                    }

                    if (channelListResponse.NextPageToken != null)
                    {
                        channelsListRequest.PageToken = channelListResponse.NextPageToken;
                    }
                } while (channelListResponse.Items.Count == 50 && channelListResponse.NextPageToken != null);

执行该命令后，我会得到：

我做错什么了吗？如果有什么可以解决的问题，请告诉我。谢谢！

好吧，很抱歉打扰你们了。我发现它是什么，在下面的代码中，我以为我只加入了50个ID，但是显然在某些情况下，我要发送更多的ID。

channelsListRequest.Id = string.Join(",", channelEntities.Select(v => v.YTChannelId));

所以我想我们可以关闭这个
