El encabezado Content-Type especifica un tipo estándar de Multipurpose Internet Mail Extensions (MIME) que describe la naturaleza de los datos recibidos o enviados. El navegador determina cómo abrir los datos a partir del valor de este encabezado. En las solicitudes y respuestas HTTP, se utiliza para indicar los tipos de objeto, lo que incluye diversos archivos multimedia como páginas web, imágenes, videos y archivos de audio. Este tema explica cómo configurar el parámetro Content-Type.
Si no especifica el encabezado Content-Type en una solicitud para cargar un objeto, los SDK de Object Storage Service (OSS) identifican el tipo de objeto según su extensión y establecen automáticamente el encabezado Content-Type con dicho tipo.
Descripción general
El encabezado Content-Type sirve para indicar el tipo de contenido del objeto. El navegador decide qué formato utilizar para leerlo con base en ese tipo de contenido.
Si no se especifica este encabezado, el valor se genera a partir de la extensión del nombre del objeto.
Cuando el nombre del objeto no incluye una extensión, se usa el valor predeterminado
application/octet-streamcomo tipo de contenido.
Especificar el encabezado Content-Type
Puede especificar el encabezado Content-Type mediante la consola de OSS, ossbrowser, los SDK de OSS, ossutil o la API de OSS. Para obtener más información, consulte Manage object metadata.
El encabezado Content-Type solo se puede especificar para un objeto a la vez. No es posible configurarlo para varios objetos de forma simultánea mediante prefijos de nombre ni extensiones.
