Cuando se cargan objetos en un bucket de Object Storage Service (OSS), se generan automáticamente direcciones URL que incluyen el endpoint público del bucket. Para acceder a estos objetos mediante un nombre de dominio personalizado, debe agregar un registro CNAME que asigne dicho dominio al bucket donde se almacenan los objetos.
Nota
Para acceder a los recursos de un bucket desde otros servicios de Alibaba Cloud dentro de la misma región, utilice un endpoint interno. Para obtener más información sobre las regiones y los endpoints compatibles, consulte Regions and endpoints.
