HP StoreAll Storage - Manual (Page 148)

IMPORTANT: For metadata, you should not exceed 90 individual key/value pairs for any one
object and the total byte length of all key/value pairs can be approximately 3KB (3072 bytes).
To post metadata to an object:
curl -X POST -i -H "X-Auth-Token:>"
<ENDPOINT>/<CONTAINER>/<file_name_in_container>
-H ':'
NOTE: The metadata must be tagged with a key and value combination. The METADATA_KEY
must follow “X-Object-Meta”. So for example, if you want to set the key to the object as “SportType”,
then the format should be X-Object-Meta-SportType. See the following sample command.
Sample command:
curl -X POST -i -H "X-Auth-Token: a424c7f293bf4c919069fa3d710f576c"

Posting metadata to a container
Examples of metadata you could post to a container are:
•
The sync key assigned to a container
•
User information
•
Information categorizing the type of content that the container should hold
To post metadata to a container:
curl -i -X POST -H "X-Auth-Token:
TOKEN>"/ -H ':'
Sample command:
For example the following command posts metadata about the Sync To and Sync Key.
curl -i -X POST -H 'X-Auth-Token:24d3fa30167f43af89a457dd2cc104c6' -H
'X-Container-Sync-To:http://10.9.34.67:8888/v1/AUTH_7b9a902423a582c9eda266dcf3ad69744037ce77e61f526b0739578e87695f32/tarcont'
-H 'X-Container-Sync-Key: sec123'
'http://10.21.20.8:8888/v1/AUTH_7b9a902423a582c9eda266dcf3ad697473909b181af608c0497bda5fa37ce321/srcont’

Downloading an object from a container
Use this command to download objects from a container.
To download an object from a container:
curl -o <LOCAL FILENAME> //
DOWNLOAD> -H "X-Auth-Token:"
Sample command:
curl -o file1
http://10.10.104.114:8888/v1/AUTH_7b9a902423a582c9eda266dcf3ad6974a2b98e4b21ea7c9e1e8d38f76afdf1b4/container1/file1
-H "X-Auth-Token:e1c7e33615bd4fa3b345ea996b05c786"
In this example, file1 is downloaded to the user’s local directory.
