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.
Request Syntax
GET /Path+
HTTP/1.1
Range: Range
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 pathpremium\canada
in the containermovies
, enter the pathpremium/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 specifypremium/canada
, the service creates acanada
subfolder in thepremium
folder. You then have two subfolders,usa
andcanada
, in thepremium
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.
