Muestras de código de Ruby

Las siguientes muestras de código, que usan la biblioteca cliente de las APIs de Google para Ruby, están disponibles para YouTube Data API. Puedes descargar estas muestras de código desde la carpeta ruby del repositorio de muestras de código de las APIs de YouTube en GitHub.

Agregar una suscripción al canal

En este ejemplo, se llama al método subscriptions.insert de la API para agregar una suscripción. a un canal específico.

Autorizar una solicitud

En la siguiente muestra de código, se realiza la autorización de OAuth 2.0 mediante la verificación de la presencia de una instancia que contiene las credenciales de autorización. Si el archivo no está presente, la secuencia de comandos abre un navegador y espera. para una respuesta, guarda las credenciales devueltas de forma local.
