GetObject

Downloads the object at the specified path. If the object’s upload availability is set to streaming, AWS Elemental MediaStore downloads the object even if it’s still uploading the object.

When an end user or a content delivery network (CDN) like Amazon CloudFront retrieves an object from MediaStore, the service returns HTTP headers that affect the caching behavior of the object. To learn more about these headers, see MediaStore's interaction with HTTP caches in the AWS Elemental MediaStore User Guide.

URI Request Parameters

The request uses the following URI parameters.

Path

The path (including the file name) where the object is stored in the container. Format: <folder name>/<folder name>/<file name>

For example, to upload the file mlaw.avi to the folder path premium\canada in the container movies, enter the path premium/canada/mlaw.avi.

Do not include the container name in this path.

If the path includes any folders that don't exist yet, the service creates them. For example, suppose you have an existing premium/usa subfolder. If you specify premium/canada, the service creates a canada subfolder in the premium folder. You then have two subfolders, usa and canada, in the premium folder.

There is no correlation between the path to the source and the path (folders) in the container in AWS Elemental MediaStore.

For more information about folders and how they exist in a container, see the AWS Elemental MediaStore User Guide.

The file name is the name that is assigned to the file that you upload. The file can have the same name inside and outside of AWS Elemental MediaStore, or it can have the same name. The file name can include or omit an extension.

Length Constraints: Minimum length of 1. Maximum length of 900.

Pattern: (?:[A-Za-z0-9_=:\.\-\~]+/){0,10}[A-Za-z0-9_=:\.\-\~]+

Required: Yes

Range

The range bytes of an object to retrieve. For more information about the Range header, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35. AWS Elemental MediaStore ignores this header for partially uploaded objects that have streaming upload availability.

Pattern: ^bytes=(?:\d+\-\d*|\d*\-\d+)$

Request Body

The request does not have a request body.
