Use GetObject with an AWS SDK or CLI

The following code examples show how to use GetObject.

CLI

AWS CLI

To download an object

The following get-object example download an object to the specified endpoint.

aws mediastore-data get-object \
    --endpoint https://aaabbbcccdddee.data.mediastore.us-west-2.amazonaws.com \
    --path=/folder_name/README.md README.md

Output:

{
    "ContentLength": "2307346",
    "ContentType": "image/jpeg",
    "LastModified": "Fri, 19 Jul 2019 21:32:20 GMT",
    "ETag": "2aa333bbcc8d8d22d777e999c88d4aa9eeeeee4dd89ff7f555555555555da6d3",
    "StatusCode": 200
}

To download part of an object

The following get-object example downloads a portion an object to the specified endpoint.

aws mediastore-data get-object \
    --endpoint https://aaabbbcccdddee.data.mediastore.us-west-2.amazonaws.com \
    --path /folder_name/README.md \
    --range="bytes=0-100" README2.md

Output:

{
    "StatusCode": 206,
    "ContentRange": "bytes 0-100/2307346",
    "ContentLength": "101",
    "LastModified": "Fri, 19 Jul 2019 21:32:20 GMT",
    "ContentType": "image/jpeg",
    "ETag": "2aa333bbcc8d8d22d777e999c88d4aa9eeeeee4dd89ff7f555555555555da6d3"
}
