我正在尝试使用 GoogleAPI YouTube 获取有关 YouTube 视频的详细信息

Question

使用 GoogleAPI v3 url 使用这个 url： https://www.googleapis.com/youtube/v3/videos?part=snippet&id=D-wxnID2q4A&key={MyKey}

我明白了 json:

我正在为 YouTube 使用 C# (Nuget) GoogleAPI，我已授予 API 权限并收到 v3 的密钥。

我的 C# 代码是：

 var      VideoID = "D-wxnID2q4A";
 var youtubeService = new YouTubeService(new BaseClientService.Initializer()
            {
                ApiKey = APT.core.Properties.Settings.Default.GoogleKey,
                ApplicationName = this.GetType().ToString()
            });


            var t=  youtubeService.Videos.List("part=snippet,id="+VideoID);

这会引发异常：

Exception:Thrown: "Google.Apis.Requests.RequestError
No filter selected. [400]
Errors [
    Message[No filter selected.] Location[ - parameter] Reason[missingRequiredParameter] Domain[youtube.parameter]
]

我做错了什么？

Answer 1

像这样的东西应该可以工作：

    var VideoID = "D-wxnID2q4A";
    var youtubeService = new YouTubeService(new BaseClientService.Initializer()
    {
        ApiKey = "{YOUR-API-KEY}",
        ApplicationName = "YouTube-test"
    });

    var t = youtubeService.Videos.List("snippet");
    t.Id = VideoID;
    var listResponse = t.Execute();

listResponse 应该包含您需要的信息。

Answer 2

  public List<VideoItem> GetCurrentChannelVideos()
    {
        var channelsListRequest = youtube.Channels.List("contentDetails");
        channelsListRequest.Mine = true;
        // Retrieve the contentDetails part of the channel resource for the authenticated user's channel.
        var channelsListResponse = channelsListRequest.Execute();
        //List<VideoLink> allVideos = new List<VideoLink>();
        List<VideoItem> allVideos = new List<VideoItem>();
        foreach (var channel in channelsListResponse.Items)
        {
            // From the API response, extract the playlist ID that identifies the list
            // of videos uploaded to the authenticated user's channel.
            var uploadsListId = channel.ContentDetails.RelatedPlaylists.Uploads;
            var nextPageToken = "";
            while (nextPageToken != null)
            {
                var playlistItemsListRequest = youtube.PlaylistItems.List("snippet,status");
                playlistItemsListRequest.PlaylistId = uploadsListId;
                playlistItemsListRequest.MaxResults = 50;
                playlistItemsListRequest.PageToken = nextPageToken;

                // Retrieve the list of videos uploaded to the authenticated user's channel.
                var playlistItemsListResponse = playlistItemsListRequest.Execute();
                allVideos.AddRange(playlistItemsListResponse.Items.Select(s => new VideoItem() { VideoID = s.Snippet.ResourceId.VideoId, ThumbnailURL = s.Snippet.Thumbnails.Default__.Url, Title = s.Snippet.Title }).ToList());
                nextPageToken = playlistItemsListResponse.NextPageToken;

            }
        }
        return allVideos;
    }
