List objects by using PHP SDK (PHP SDK V1) - Object Storage Service

En este tema se describe cómo listar todos los objetos, una cantidad específica de objetos y aquellos cuyo nombre contiene un prefijo determinado dentro de un bucket de Object Storage Service (OSS).

Notas de uso

En este tema se utiliza el endpoint público de la región China (Hangzhou). Si necesita acceder a OSS desde otros servicios de Alibaba Cloud en la misma región, utilice un endpoint interno. Para más información sobre las regiones y los endpoints compatibles, consulte Regions and endpoints.
Aquí se muestra cómo crear una instancia de OSSClient con un endpoint de OSS. Para conocer configuraciones alternativas, como usar un dominio personalizado o autenticarse con credenciales de Security Token Service (STS), consulte Create an OssClient.
Para listar objetos, debe contar con el permiso oss:ListObjects. Para más información, consulte Attach a custom policy to a RAM user.

Listar objetos

Llame al método listObjects o listObjectsV2 para listar los objetos del directorio raíz de un bucket específico. Los subdirectorios y los objetos que contienen no se incluyen en el resultado.

Uso del método listObjects

A continuación se muestra cómo llamar al método listObjects para listar los objetos del directorio raíz de un bucket llamado examplebucket. Los subdirectorios y sus objetos no se incluyen. De forma predeterminada, se devuelven 100 objetos.

Especificar la codificación de los nombres de objeto

Si el nombre de un objeto contiene caracteres especiales, debe codificarlo antes de transmitirlo. OSS solo es compatible con la codificación URL.

Comillas simples (')
Comillas dobles (")
Signos et (&)
Signos de mayor que y menor que (< >)
Comas de enumeración (、)
Caracteres chinos

Llame al método listObjects o listObjectsV2 para especificar la codificación de los nombres de objeto.

Simular directorios

OSS utiliza una estructura plana en la que todos los datos se almacenan como objetos. Para simular un directorio, cree un objeto de 0 bytes cuyo nombre termine con una barra diagonal (/). Este objeto se puede cargar y descargar. La consola de OSS muestra los objetos cuyos nombres terminan con una barra diagonal (/) como directorios.

Para listar objetos por directorio, especifique los parámetros delimiter y prefix.

Si establece prefix con el nombre de un directorio en la solicitud, se listan los objetos y subdirectorios cuyos nombres contienen ese prefijo.
Si especifica un prefijo y establece delimiter con una barra diagonal (/) en la solicitud, se listan los objetos y subdirectorios del directorio cuyos nombres comienzan con el prefijo indicado. Cada subdirectorio aparece como un único elemento de resultado en CommonPrefixes. Los objetos y directorios dentro de estos subdirectorios no se listan.

Por ejemplo, suponga que un bucket contiene los siguientes objetos: oss.jpg, fun/test.jpg, fun/movie/001.avi y fun/movie/007.avi. Se especifica la barra diagonal (/) como delimitador de directorios. A continuación se describe cómo listar objetos en directorios simulados.
