以下不說明如何匯入YouTube API Lib與其使用申請，網路上很多，可自行參考。
基本的建立UserCredential，並宣告YouTubeService，每個動作都是需要此步驟
UserCredential credential;
using( var stream = new FileStream(System.IO.Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase, "client_secrets.json"), FileMode.Open, FileAccess.Read) )
{
credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
new[] { YouTubeService.Scope.Youtube, YouTubeService.Scope.YoutubeUpload },
"user",
CancellationToken.None,
new FileDataStore(System.IO.Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase, "YoutubeCredential"))
);
}
youtubeService = new YouTubeService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
});
Upload
上傳單一影片檔案
var video = new Video();
video.Snippet = new VideoSnippet();
video.Snippet.Title = videoName;
video.Snippet.Description = videoName;
video.Snippet.Tags = new string[] { "LowRes", processingTag };
video.Snippet.CategoryId = conf.configMapper.ey_sec.ey_youtube_category;//"22"; See https://developers.google.com/youtube/v3/docs/videoCategories/list
video.Status = new VideoStatus();
video.Status.PrivacyStatus = conf.configMapper.ey_sec.ey_youtube_privacy; //"unlisted" or "private" or "public"
var filePath = target; // Replace with path to actual movie file.
try
{
using( var fileStream = new FileStream(filePath, FileMode.Open) )
{
var videosInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "video/*");
const int KB = 0x400;
var minimumChunkSize = 256 * KB;
videosInsertRequest.ProgressChanged += videosInsertRequest_ProgressChanged;
videosInsertRequest.ResponseReceived += videosInsertRequest_ResponseReceived;
videosInsertRequest.ChunkSize = minimumChunkSize * 32;
await videosInsertRequest.UploadAsync();
}
}
catch(Exception ex)
{
logtext.Out("[YouTube Exception] " + ex.Message + ex.StackTrace);
}
Check&Update
檢查VideoID是否有效並檢查是否為Duplicate video，並更新Tag資訊
var my_video_request = youtubeService.Videos.List("snippet, status");
my_video_request.Id = oldVideoID; // the Youtube video id of the video you want to update
my_video_request.MaxResults = 1;
var my_video_response = await my_video_request.ExecuteAsync();
if( my_video_response.Items.Count == 0 )
{
return;
}
var video = my_video_response.Items[0];
video.Snippet.Tags.Add(oldVersionTag);
if( video.Status.UploadStatus == "rejected" )
{
logtext.Out("[YouTube Info] Video upload status : " + video.Status.UploadStatus);
logtext.Out("[YouTube Info] Video upload reject reason : " + video.Status.RejectionReason);
}
// and tell the changes we want to youtube
var my_update_request = youtubeService.Videos.Update(video, "snippet, status");
my_update_request.Execute();
Delete
刪除特定VideoID之影片
try
{
var my_video_request = youtubeService.Videos.List("snippet, status");
my_video_request.Id = oldVideoID; // the Youtube video id of the video you want to update
my_video_request.MaxResults = 1;
var my_video_response = await my_video_request.ExecuteAsync();
if( my_video_response.Items.Count != 0 )
{
logtext.Out("[Info ] Old VideoID [" + oldVideoID + "] is valid, then delete it.");
var my_update_request = youtubeService.Videos.Delete(oldVideoID);
my_update_request.Execute();
}
}
catch(Exception ex)
{
logtext.Out("[YouTube Exception] " + ex.Message + ex.StackTrace);
}
List
列出所有YouTube上的所有Video ID
try
{
var channelsListRequest = youtubeService.Channels.List("contentDetails");
channelsListRequest.Mine = true;
var channelsListResponse = channelsListRequest.Execute();
foreach( var channel in channelsListResponse.Items )
{
var uploadsListId = channel.ContentDetails.RelatedPlaylists.Uploads;
var nextPageToken = "";
while( nextPageToken != null )
{
var playlistItemsListRequest = youtubeService.PlaylistItems.List("snippet");
playlistItemsListRequest.PlaylistId = uploadsListId;
playlistItemsListRequest.MaxResults = 50;
playlistItemsListRequest.PageToken = nextPageToken;
var playlistItemsListResponse = playlistItemsListRequest.Execute();
foreach( var playlistItem in playlistItemsListResponse.Items )
{
string id = playlistItem.Snippet.ResourceId.VideoId;
videoIDList.Add(id);
}
nextPageToken = playlistItemsListResponse.NextPageToken;
}
}
}
catch( Exception ex )
{
logtext.Out("[Exception] " + ex.Message + ex.StackTrace);
}
