C# 从channel-Youtube API v3 c获取所有视频#

是否可以从某个频道（不是我的）获取所有视频？

---

如果可能的话，我可以使用一个简单的api密钥，还是应该使用OAuth 2.0凭据？

我已经用这种方式完成了，它对我很有效 我使用了Nuget数据包管理器中的Youtube API v3

using Google.Apis.Services;
using Google.Apis.YouTube.v3;

public ActionResult GetVideo(YouTubeData objYouTubeData)
{
    try
    {
        var yt = new YouTubeService(new BaseClientService.Initializer() { ApiKey = "Your API Key" });
        var channelsListRequest = yt.Channels.List("contentDetails");
        channelsListRequest.ForUsername = "kkrofficial";
        var channelsListResponse = channelsListRequest.Execute();
        foreach (var channel in channelsListResponse.Items)
        {
            // of videos uploaded to the authenticated user's channel.
            var uploadsListId = channel.ContentDetails.RelatedPlaylists.Uploads;
            var nextPageToken = "";
            while (nextPageToken != null)
            {
                var playlistItemsListRequest = yt.PlaylistItems.List("snippet");
                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();
                foreach (var playlistItem in playlistItemsListResponse.Items)
                {
                    // Print information about each video.
                    //Console.WriteLine("Video Title= {0}, Video ID ={1}", playlistItem.Snippet.Title, playlistItem.Snippet.ResourceId.VideoId);
                    var qry = (from s in ObjEdbContext.ObjTubeDatas where s.Title == playlistItem.Snippet.Title select s).FirstOrDefault();
                    if (qry == null)
                    {
                        objYouTubeData.VideoId = "https://www.youtube.com/embed/" + playlistItem.Snippet.ResourceId.VideoId;
                        objYouTubeData.Title = playlistItem.Snippet.Title;
                        objYouTubeData.Descriptions = playlistItem.Snippet.Description;
                        objYouTubeData.ImageUrl = playlistItem.Snippet.Thumbnails.High.Url;
                        objYouTubeData.IsValid = true;
                        ObjEdbContext.ObjTubeDatas.Add(objYouTubeData);
                        ObjEdbContext.SaveChanges();
                        ModelState.Clear();

                    }
                }
                nextPageToken = playlistItemsListResponse.NextPageToken;
            }
        }
    }
    catch (Exception e)
    {
        ViewBag.ErrorMessage = "Some exception occured" + e;
        return RedirectToAction("GetYouTube");
    }

    return RedirectToAction("GetYouTube");
}

请在此行中提供您的频道名称

channelsListRequest.ForUsername = "kkrofficial"; //kkrofficial is kkr channel name.

您可以使用API密钥查询所有频道的视频（即使不是您的：）

公共任务GetVideosFromChannelAsync（字符串ytChannelId） { 返回任务。运行（（）=> { List res=新列表（）； 字符串nextpagetoken=“”； while（nextpagetoken！=null） { var searchListRequest=_youtubeService.Search.List（“代码段”）； searchListRequest.MaxResults=50； searchListRequest.ChannelId=ytChannelId； searchListRequest.PageToken=nextpagetoken； searchListRequest.Type=“视频”； //调用search.list方法检索与指定查询词匹配的结果。 var searchListResponse=searchListRequest.Execute（）； //处理视频响应 res.AddRange（searchListResponse.Items）； nextpagetoken=searchListResponse.nextpagetoken； } 返回res； }); }

这个方法应该会让你走上正轨

那么ClientServiceRequest.cs呢？我应该这样做吗？我已经创建了API，但在我的应用程序中，我得到了错误消息：访问未配置。您的项目未启用API（YouTube数据API）。请使用Google开发者控制台更新您的配置。[403]不需要ClientServiceRequest.cs…只需从Nuget Packet manager安装Youtube API v3即可

        public Task<List<SearchResult>> GetVideosFromChannelAsync(string ytChannelId)
    {

        return Task.Run(() =>
        {
            List<SearchResult> res = new List<SearchResult>();

            string nextpagetoken = " ";

            while (nextpagetoken != null)
            {
                var searchListRequest = _youtubeService.Search.List("snippet");
                searchListRequest.MaxResults = 50;
                searchListRequest.ChannelId = ytChannelId;
                searchListRequest.PageToken = nextpagetoken;
                searchListRequest.Type      = "video";

                // Call the search.list method to retrieve results matching the specified query term.
                var searchListResponse = searchListRequest.Execute();

                // Process  the video responses 
                res.AddRange(searchListResponse.Items);

                nextpagetoken = searchListResponse.NextPageToken;

            }

            return res;

        });
    }
