Haz clic en Aceptar para descartar el diálogo resultante.
Haz clic en el botón file_download
(Descargar JSON) a la derecha del ID de cliente.
Mueve el archivo descargado a tu directorio de trabajo y cámbiale el nombre a client_secret.json.
Paso 2: Instala la biblioteca cliente de Google
Ejecuta el siguiente comando para instalar la biblioteca:
gem install google-api-client
Consulta la página de instalación de la biblioteca para ver las opciones de instalación alternativas.
Paso 3: Configura la muestra
Crea un archivo llamado quickstart.rb en tu directorio de trabajo y copia el siguiente código:

La primera vez que ejecutes la muestra, se te solicitará que autorices el acceso:
La muestra intenta abrir una nueva ventana o pestaña en tu navegador predeterminado.
Si esto falla, copia la URL de la consola y ábrela manualmente en tu navegador.
Si aún no accediste a tu Cuenta de Google, se te solicitará que lo hagas. Si accediste a varias Cuentas de Google, se te pedirá que selecciones una para la autorización.
Haz clic en el botón Aceptar.
Copia el código que se te proporciona, pégalo en el símbolo del sistema y presiona Intro. El código puede aparecer en la URL de la página a la que se te redirecciona después de otorgar la autorización:
La información de autorización se almacena en el sistema de archivos, por lo que las ejecuciones posteriores no solicitarán autorización.
El flujo de autorización de este ejemplo está diseñado para una aplicación de línea de comandos. Si deseas obtener información para realizar la autorización en una aplicación web, consulta Cómo usar OAuth 2.0 para aplicaciones de servidor web.

Use\n [this wizard](https://console.developers.google.com/start/api?id=youtube)\n to create or select a project in the Google Developers Console and\n automatically turn on the API. Click **Continue** , then\n **Go to credentials**.\n\n2. On the **Create credentials** page, click the\n **Cancel** button.\n\n3. At the top of the page, select the **OAuth consent screen** tab.\n Select an **Email address** , enter a **Product name** if not\n already set, and click the **Save** button.\n\n4. Select the **Credentials** tab, click the **Create credentials**\n button and select **OAuth client ID**.\n\n5. Select the application type **Other** , enter the name\n \"YouTube Data API Quickstart\", and click the **Create** button.\n\n6. Click **OK** to dismiss the resulting dialog.\n\n7. Click the file_download\n (Download JSON) button to the right of the client ID.\n\n8. Move the downloaded file to your working directory and rename it\n `client_secret.json`.\n\nStep 2: Install the Google Client Library\n-----------------------------------------\n\nRun the following command to install the library: \n\n gem install google-api-client\n\nSee the library's [installation\npage](/api-client-library/ruby/start/installation) for the alternative\ninstallation options.\n\nStep 3: Set up the sample\n-------------------------\n\nCreate a file named `quickstart.rb` in your working directory and copy in the\nfollowing code:\n\n\n```ruby\n# Sample Ruby code for user authorization\n\nrequire 'rubygems'\ngem 'google-api-client', '\u003e0.7'\nrequire 'google/apis'\nrequire 'google/apis/youtube_v3'\nrequire 'googleauth'\nrequire 'googleauth/stores/file_token_store'\n\nrequire 'fileutils'\nrequire 'json'\n\n# REPLACE WITH VALID REDIRECT_URI FOR YOUR CLIENT\nREDIRECT_URI = 'http://localhost'\nAPPLICATION_NAME = 'YouTube Data API Ruby Tests'\n\n# REPLACE WITH NAME/LOCATION OF YOUR client_secrets.json FILE\nCLIENT_SECRETS_PATH = 'client_secret.json'\n\n# REPLACE FINAL ARGUMENT WITH FILE WHERE CREDENTIALS WILL BE STORED\nCREDENTIALS_PATH = File.join(Dir.home, '.credentials',\n \"youtube-quickstart-ruby-credentials.yaml\")\n\n# SCOPE FOR WHICH THIS SCRIPT REQUESTS AUTHORIZATION\nSCOPE = Google::Apis::YoutubeV3::AUTH_YOUTUBE_READONLY\n\ndef authorize\n FileUtils.mkdir_p(File.dirname(CREDENTIALS_PATH))\n\n client_id = Google::Auth::ClientId.from_file(CLIENT_SECRETS_PATH)\n token_store = Google::Auth::Stores::FileTokenStore.new(file: CREDENTIALS_PATH)\n authorizer = Google::Auth::UserAuthorizer.new(\n client_id, SCOPE, token_store)\n user_id = 'default'\n credentials = authorizer.get_credentials(user_id)\n if credentials.nil?\n url = authorizer.get_authorization_url(base_url: REDIRECT_URI)\n puts \"Open the following URL in the browser and enter the \" +\n \"resulting code after authorization\"\n puts url\n code = gets\n credentials = authorizer.get_and_store_credentials_from_code(\n user_id: user_id, code: code, base_url: REDIRECT_URI)\n end\n credentials\nend\n\n# Initialize the API\nservice = Google::Apis::YoutubeV3::YouTubeService.new\nservice.client_options.application_name = APPLICATION_NAME\nservice.authorization = authorize\n\n# Sample ruby code for channels.list\n\ndef channels_list_by_username(service, part, **params)\n response = service.list_channels(part, params).to_json\n item = JSON.parse(response).fetch(\"items\")[0]\n\n puts (\"This channel's ID is #{item.fetch(\"id\")}. \" +\n \"Its title is '#{item.fetch(\"snippet\").fetch(\"title\")}', and it has \" +\n \"#{item.fetch(\"statistics\").fetch(\"viewCount\")} views.\")\nend\n\nchannels_list_by_username(service, 'snippet,contentDetails,statistics', for_username: 'GoogleDevelopers')\nhttps://github.com/youtube/api-samples/blob/07263305b59a7c3275bc7e925f9ce6cabf774022/ruby/quickstart.rb\n```\n\n\u003cbr /\u003e\n\nStep 4: Run the sample\n----------------------\n\nRun the sample using the following command: \n\n ruby quickstart.rb\n\nThe first time you run the sample, it will prompt you to authorize access:\n\n1. The sample attempts to open a new window or tab in your default browser.\n If this fails, copy the URL from the console and manually open it in\n your browser.\n\n If you are not already logged into your Google account, you are\n prompted to log in. If you are logged into multiple Google accounts,\n you are asked to select one account to use for the authorization.\n2. Click the **Accept** button.\n3. Copy the code you're given, paste it into the command-line prompt, and press\n **Enter**. The code may appear in the URL of the page you are redirected to\n after granting authorization:\n\n ```\n http://localhost/?code=4/nr_1TspmmQPFyifh7nz...OFo#\n ```\n\nIt worked! **Great!** Check out the further reading section below to learn more.\nI got an error **Bummer.** Thanks for letting us know and we'll work to fix this quickstart.\n\nNotes\n-----\n\n- Authorization information is stored on the file system, so subsequent executions will not prompt for authorization.\n- The authorization flow in this example is designed for a command-line application. For information on how to perform authorization in a web application, see [Using OAuth 2.0 for Web Server Applications](/youtube/v3/guides/auth/server-side-web-apps).\n\nFurther reading\n---------------\n\n- [Google Developers Console help documentation](/console/help/new)\n- [Google APIs Client for Ruby documentation](/api-client-library/ruby)\n- [YouTube Data API reference documentation](/youtube/v3/docs)"]]
