如何在c＃中使用Youtube直播API？

Question

我想创建一个WPF应用程序，从我的ip camera获取视频并将其发送到我的youtube频道。我浏览了所有的网站，但没有例子我怎么能用c＃将视频直播到Youtube。谷歌网站上有一些例子，但它们是用PHP，Java和Phyton编写的，但我不了解这种编程语言，所以我无法使用API​​。

我试着写一点，但它没有用。这是我通过Java示例编写的代码。

UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
          new ClientSecrets { ClientId = "MyClientId", ClientSecret = "MyClientSecret" },
          new[] { DriveService.Scope.Drive,
            DriveService.Scope.DriveFile },
          "My Youtube Channel Name",
          CancellationToken.None,
          new FileDataStore("Drive.Auth.Store")).Result;

        string devkey = "AIzaSyCbxm6g9orAw9PF3MkzTb_0PGbpD3Xo1Qg";
        string username = "MyYoutubeChannelEmailAdress";
        string password = "MyPassword";

        YouTubeRequestSettings youtubereqsetting = new YouTubeRequestSettings("API Project", devkey, username, password);

        YouTubeRequest youtubereq = new YouTubeRequest(youtubereqsetting);

        LiveBroadcastSnippet broadcastSnippet = new LiveBroadcastSnippet();

        broadcastSnippet.Title = "Test Live Stream";
        broadcastSnippet.ScheduledStartTime = new DateTime(2015, 3, 12, 19, 00, 00);
        broadcastSnippet.ScheduledEndTime = new DateTime(2015, 3, 12, 20, 00, 00);


        LiveBroadcastStatus status = new LiveBroadcastStatus();
        status.PrivacyStatus = "Private";

        LiveBroadcast broadcast = new LiveBroadcast();

        broadcast.Kind = "youtube#liveBroadcast";
        broadcast.Snippet = broadcastSnippet;
        broadcast.Status = status;

        Google.Apis.YouTube.v3.LiveBroadcastsResource.InsertRequest liveBroadcastInsert = new Google.Apis.YouTube.v3.LiveBroadcastsResource.InsertRequest(service, broadcast, "");            
        LiveBroadcast returnLiveBroadcast = liveBroadcastInsert.Execute();

请帮帮我！？！？！？

Answer 1

看起来您正在尝试使用ClientLogin，因为我看到用户名和通行证。 而是使用OAuth2并使用these samples for guidance。

Answer 2

以下是我设法使其发挥作用的方式：

1. 创建应用 - Google Developer Console
2. 在您的应用上启用API - Youtube Data API v3
3. 创建OAuth客户端ID - Create OAuth Credential
4. 必须将应用程序类型设置为其他
5. 将您的客户端ID和客户端密钥复制到安全的位置。
6. 访问以下网址（您应该使用将广播直播视频的Google帐户进行记录）：

  

https://accounts.google.com/o/oauth2/auth?client_id=的 CLIENT_ID ＆安培;范围= https://gdata.youtube.com&response_type=code&access_type=offline&redirect_uri=urn:ietf:wg:oauth:2.0:oob

     

使用第3步

生成的客户ID更改 CLIENT_ID

1. 从页面上的输入文本框中复制生成的令牌。

2. 使用某种工具（cURL，wget，Google Chrome的Postman插件，无论......）向以下网址发出POST请求：

     

   https://accounts.google.com/o/oauth2/token

        

   使用以下字段对此网址进行HTTP POST x-www-form-urlencoded :(仅更改client_id，client_token和代码，首先保留2）。

   {
       grant_type=authorization_code,
       redirect_uri=urn:ietf:wg:oauth2.0:oob,
       code=token_from_step_6_&_7
       client_id=your_client_id,
       client_secret=your_client_secret,
   }
   

3. 如果在此之前看起来都很好，你应该得到像这样的答案：

   {
   "access_token" : "token valid for next few minutes. WE DON'T WANT THIS ONE",
   "token_type" : "Bearer",
   "expires_in" : 3600,
   "refresh_token" : "token valid for offline app. COPY THIS ONE, AND STORE IT"
   }
   

4. 现在，我们拥有所需的所有身份验证数据（client_id，client_secret，refresh_token），是时候使用API​​了。

       public String CreateLiveBroadcastEvent(String eventTitle, DateTime eventStartDate)
      {
           ClientSecrets secrets = new ClientSecrets()
           {
               ClientId = CLIENT_ID,
               ClientSecret = CLIENT_SECRET
           };
           var token = new TokenResponse { RefreshToken = REFRESH_TOKEN };
           var credentials = new UserCredential(new GoogleAuthorizationCodeFlow(
           new GoogleAuthorizationCodeFlow.Initializer { ClientSecrets = secrets }),
           "user", token);
           var service = new YouTubeService(new BaseClientService.Initializer
           {
               HttpClientInitializer = credentials,
               ApplicationName = "your-app-name"
           });
           var broadcast = new LiveBroadcast
           {
               Kind = "youtube#liveBroadcast",
               Snippet = new LiveBroadcastSnippet
               {
                   Title = eventTitle,
                   ScheduledStartTime = eventStartDate
               },
               Status = new LiveBroadcastStatus { PrivacyStatus = "public" }
           };
           var request = service.LiveBroadcasts.Insert(broadcast, "id,snippet,status");
           var response = request.Execute();
           return response.Id;
       }
