Google Developer API V3 for video upload in YouTube C#.net

2.4k views Asked by At

I have been using google's reputed API V2 for uploading the videos on YouTube from my web application as there has been up gradation in API to V3 , I am unable to upload the same through the same code.

I have tried with the new application for uploading the video on YouTube with V3, but there are many things which were there before but not available in V3

OLD: From: Google.Gdata.YouTube.Youtubeservice

YouTubeService service = new YouTubeService(applicationName,developerKey);
service.setUserCredentials(googleEmail, googleEmailPassword);

NEW: From : Google.Apis.Youtube.V3.YoutubeService

YouTubeService service = new YouTubeService();` -- its doesn't have the set credentials

I have gone through YouTube Data API .NET Code Samples, but it was not much useful as it’s an console application.

You cant use Login and password anymore. You need to use Oauth2 to authenticate a user. The code is the same if it is a web or a console application.

/// <summary>
/// Authenticate to Google Using Oauth2
/// Documentation https://developers.google.com/accounts/docs/OAuth2
/// </summary>
/// <param name="clientId">From Google Developer console https://console.developers.google.com</param>
/// <param name="clientSecret">From Google Developer console https://console.developers.google.com</param>
/// <param name="userName">A string used to identify a user.</param>
/// <returns></returns>
public static YouTubeService AuthenticateOauth(string clientId, string clientSecret, string userName)
        {

            string[] scopes = new string[] { YouTubeService.Scope.Youtube,  // view and manage your YouTube account
                                             YouTubeService.Scope.YoutubeForceSsl,
                                             YouTubeService.Scope.Youtubepartner,
                                             YouTubeService.Scope.YoutubepartnerChannelAudit,
                                             YouTubeService.Scope.YoutubeReadonly,
                                             YouTubeService.Scope.YoutubeUpload}; 

            try
            {
                // here is where we Request the user to give us access, or use the Refresh Token that was previously stored in %AppData%
                UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets { ClientId = clientId, ClientSecret = clientSecret }
                                                                                             , scopes
                                                                                             , userName
                                                                                             , CancellationToken.None
                                                                                             , new FileDataStore("Daimto.YouTube.Auth.Store")).Result;

                YouTubeService service = new YouTubeService(new YouTubeService.Initializer()
                {
                    HttpClientInitializer = credential,
                    ApplicationName = "YouTube Data API Sample",
                });
                return service;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.InnerException);
                return null;

            }

        }    }

Usage:

 // Authenticate Oauth2
    String CLIENT_ID = "xxxxx-d0vpdthl4ms0soutcrpe036ckqn7rfpn.apps.googleusercontent.com";
    String CLIENT_SECRET = "NDmluNfTgUk6wgmy7cFo64RV";
    var service = Authentication.AuthenticateOauth(CLIENT_ID, CLIENT_SECRET, "test");
