Restaurar archivos (SDK de Browser.js) - Object Storage Service - Centro de documentación de Alibaba Cloud

Los objetos Archive y Cold Archive deben restaurarse antes de poder leerse. En este tema se describe cómo restaurar objetos Archive y Cold Archive.

Notas de uso

Cuando utilice herramientas de empaquetado como Webpack y Browserify, instale el SDK de OSS para Browser.js con el comando npm install ali-oss.
Si desea acceder a un bucket de OSS desde un navegador, pero no hay reglas de CORS configuradas para ese bucket, el navegador rechazará la solicitud. Por lo tanto, configure las reglas de CORS del bucket si quiere acceder a él desde un navegador. Para obtener más información, consulte Installation.
En la mayoría de los casos, el SDK de OSS para Browser.js se utiliza en navegadores. Para evitar que su par de AccessKey quede expuesto, se recomienda usar credenciales de acceso temporales obtenidas de Security Token Service (STS) para acceder a OSS.

Las credenciales de acceso temporales constan de un par de AccessKey y un token de seguridad. El par de AccessKey está formado por un AccessKey ID y un AccessKey secret. Para obtener más información sobre cómo conseguir credenciales de acceso temporales, consulte Use STS for temporary access authorization.
