将视频上传到 youtube 时，我如何知道什么类别 ID 是什么类别名称？

Question

我正在向 yourube 上传视频：在 form1 构造函数中：

UserCredential credential;
            using (FileStream stream = new FileStream(@"D:\C-Sharp\Youtube-Manager\Youtube-Manager\Youtube-Manager\bin\Debug\client_secrets.json", FileMode.Open, FileAccess.Read))
            {
                credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                    GoogleClientSecrets.Load(stream).Secrets,
                    new[] { YouTubeService.Scope.Youtube, YouTubeService.Scope.YoutubeUpload },
                    "user",
                    CancellationToken.None,
                    new FileDataStore("YouTube.Auth.Store")).Result;
            }
            var youtubeService = new YouTubeService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
            });
            var video = new Video();
            video.Snippet = new VideoSnippet();
            video.Snippet.Title = "Default Video Title";
            video.Snippet.Description = "Default Video Description";
            video.Snippet.Tags = new string[] { "tag1", "tag2" };
            video.Snippet.CategoryId = "22"; // See https://developers.google.com/youtube/v3/docs/videoCategories/list
            video.Status = new VideoStatus();
            video.Status.PrivacyStatus = "public";
            var filePath = @"C:\Users\bout0_000\Videos\test.mp4";
            using (var fileStream = new FileStream(filePath, FileMode.Open))
            {

                const int KB = 0x400;
                var minimumChunkSize = 256 * KB;

                var videosInsertRequest = youtubeService.Videos.Insert(video,
                    "snippet,status", fileStream, "video/*");
                videosInsertRequest.ProgressChanged +=
                    videosInsertRequest_ProgressChanged;
                videosInsertRequest.ResponseReceived +=
                    videosInsertRequest_ResponseReceived;
                videosInsertRequest.ChunkSize = minimumChunkSize * 4;
                videosInsertRequest.Upload();
            }

在此示例中，我使用的是类别编号 22

video.Snippet.CategoryId = "22";

只有在上传视频后，我在我的视频的 youtube 网站上看到这个类别是：人物和博客

如果我正在浏览此 link https://developers.google.com/youtube/v3/docs/videoCategories/list，我可以在底部播放使用 OAuth 2.0 的授权请求。

但我还是不明白在哪里可以按名称和 ID 查看所有类别的完整列表？例如：名称：人物和博客 ID：22

找不到显示它的任何网站。

Answer 1

拨打 API 电话至：

https://www.googleapis.com/youtube/v3/videoCategories?part=snippet&regionCode={two-character-region}&key={YOUR_API_KEY}

并且 API 将 return 您选择的区域的所有类别（名称和 ID）。请注意，同一类别在所有地区应具有相同的 ID；但是，某些类别在某些地区不可用（这就是为什么您必须进行 API 调用...地区太多，无法以友好的方式列出所有可能的排列）。

下面是我程序中的 VB .NET 源代码。此代码加载带有自定义 Class (CategoryClass) 的 ComboBox，其中包括所有有效的 CategoryId 和标题。我还包含了我的 Custom Class: CategoryClass。您可以使用其中一种免费转换器将其转换为 C# .NET。

Private Sub GetVideoCategories()
    Dim objYouTubeService As YouTubeService
    AddToLog("GetVideoCategories Begin", True, False)
    Try
        objYouTubeService = New YouTubeService(New BaseClientService.Initializer() With { _
             .HttpClientInitializer = OAUth2Credential, _
             .ApplicationName = Assembly.GetExecutingAssembly().GetName().Name})
    Catch ex As Exception
        MsgBox(ex.Message, MsgBoxStyle.Critical, "GetVideoCategories - Initialize YouTubeService")
        End
    End Try
    Dim objCategories As VideoCategoryListResponse = Nothing
    Try
        Dim objRequest As VideoCategoriesResource.ListRequest = New VideoCategoriesResource.ListRequest(objYouTubeService, "id,snippet")
        objRequest.Hl = "en_US"
        objRequest.RegionCode = "US"
        objCategories = objRequest.Execute
    Catch ex As Exception
        MsgBox(ex.Message, MsgBoxStyle.Critical, "GetVideoCategories - VideoCategories List Request")
        End
    End Try
    cmbCategory.DisplayMember = "Title"
    cmbCategory.ValueMember = "Id"
    For Each obj As VideoCategory In objCategories.Items
        cmbCategory.Items.Add(New CategoryClass(obj.Id, obj.Snippet.Title))
        If obj.Snippet.Title.Contains("News") Then
            intDefaultCategoryIndex = cmbCategory.Items.Count - 1
        End If
    Next
    cmbCategory.SelectedIndex = intDefaultCategoryIndex
    AddToLog("GetVideoCategories End", True, False)
End Sub




Friend Class CategoryClass
Dim m_Id As String
Dim m_Title As String
Sub New(ByVal Id As String, ByVal Title As String)
    m_Id = Id
    m_Title = Title
End Sub
Property ID As String
    Get
        ID = m_Id
    End Get
    Set(value As String)
        m_Id = value
    End Set
End Property
Property Title As String
    Get
        Title = m_Title
    End Get
    Set(value As String)
        m_Title = value
    End Set
End Property
Overrides Function ToString() As String
    ToString = m_Id & "|" & m_Title
End Function
End Class
