Ejemplos de Amazon S3 usando SDK para Ruby

Los siguientes ejemplos de código muestran cómo realizar acciones e implementar situaciones comunes AWS SDK for Ruby mediante Amazon S3.

Los conceptos básicos son ejemplos de código que muestran cómo realizar las operaciones esenciales dentro de un servicio.

Las acciones son extractos de código de programas más grandes y deben ejecutarse en contexto. Mientras las acciones muestran cómo llamar a las distintas funciones de servicio, es posible ver las acciones en contexto en los escenarios relacionados.

Los escenarios son ejemplos de código que muestran cómo llevar a cabo una tarea específica a través de llamadas a varias funciones dentro del servicio o combinado con otros Servicios de AWS.

En cada ejemplo se incluye un enlace al código de origen completo, con instrucciones de configuración y ejecución del código en el contexto.

Introducción

En los siguientes ejemplos de código se muestra cómo empezar a utilizar Amazon S3.

Ejemplos de tecnología sin servidor

En el siguiente ejemplo de código se muestra cómo implementar una función de Lambda que recibe un evento activado al cargar un objeto en un bucket de S3. La función recupera el nombre del bucket de S3 y la clave del objeto del parámetro de evento y llama a la API de Amazon S3 para recuperar y registrar el tipo de contenido del objeto.
