get-object¶

Description¶

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.

Synopsis¶

  get-object
--path <value>
[--range <value>]
<outfile>

Options¶

--path (string)

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.

--range (string)

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.

outfile (string) Filename where the content will be saved

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To download an entire object

The following get-object example downloads the specified object.

aws mediastore-data get-object \
    --endpoint https://aaabbbcccdddee.data.mediastore.us-west-2.amazonaws.com \
    --path events/baseball/setup.jpg setup.jpg

Output:

{
    "ContentType": "image/jpeg",
    "StatusCode": 200,
    "ETag": "2aa333bbcc8d8d22d777e999c88d4aa9eeeeee4dd89ff7f555555555555da6d3",
    "ContentLength": "3860266",
    "LastModified": "Fri, 19 Jul 2019 21:50:31 GMT"
}

Example 2: To download part of an object

The following get-object example downloads the specified part of an object.

aws mediastore-data get-object \
    --endpoint https://aaabbbcccdddee.data.mediastore.us-west-2.amazonaws.com \
    --path events/baseball/setup.jpg setup.jpg \
    --range "bytes=0-100"

Output:

{
    "StatusCode": 206,
    "LastModified": "Fri, 19 Jul 2019 21:50:31 GMT",
    "ContentType": "image/jpeg",
    "ContentRange": "bytes 0-100/3860266",
    "ETag": "2aa333bbcc8d8d22d777e999c88d4aa9eeeeee4dd89ff7f555555555555da6d3",
    "ContentLength": "101"
}

Output¶

Body -> (streaming blob)

The bytes of the object.

CacheControl -> (string)

An optional CacheControl header that allows the caller to control the object’s cache behavior. Headers can be passed in as specified in the HTTP spec at https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9 .

Headers with a custom user-defined value are also accepted.

ContentRange -> (string)

The range of bytes to retrieve.

ContentLength -> (long)

The length of the object in bytes.

ContentType -> (string)

The content type of the object.

ETag -> (string)

The ETag that represents a unique instance of the object.

LastModified -> (timestamp)

The date and time that the object was last modified.

StatusCode -> (integer)

The HTML status code of the request. Status codes ranging from 200 to 299 indicate success. All other status codes indicate the type of error that occurred.
