Los siguientes ejemplos de código, que utilizan la Biblioteca cliente de API de Google para Ruby, están disponibles para YouTube Data API.
Autorizar una solicitud
El código de ejemplo a continuación realiza la autorización OAuth 2.0 mediante la comprobación de la presencia de un archivo local que contiene las credenciales de autorización. Si el archivo no está presente, la secuencia de comandos abre un navegador y espera una respuesta, luego, guarda las credenciales devueltas a nivel local.
require 'google/api_client' require 'google/api_client/client_secrets' require 'json' require 'launchy' require 'thin' RESPONSE_HTML = <<stop <html> <head> <title>OAuth 2 Flow Complete</title> </head> <body> You have successfully completed the OAuth 2 flow. Please close this browser window and return to your program. </body> </html> stop FILE_POSTFIX = '-oauth2.json' # Small helper for the sample apps for performing OAuth 2.0 flows from the command # line.

Recuperar mis videos subidos
El siguiente ejemplo de código invoca el método playlistItems.list
de la API para recuperar una lista de videos subidos en el canal asociado a la solicitud. El código también invoca el método channels.list
con el parámetro mine
establecido en true
para recuperar el ID de lista de reproducción que identifica a los videos subidos del canal.
