Lists containers for an account. Creates, updates, shows, and
|
|
deletes account metadata. For more information and concepts about
|
|
accounts see `Object Storage API overview

<http://docs.openstack.org/developer/swift/api/object_api_v1_overview.html>`_.

Show account details and list containers
|
|
========================================
|
|
|
|
.. rest_method:: GET /v1/{account}
|
|
|
|
Shows details for an account and lists containers, sorted by name, in the account.
|
|
|
|
The sort order for the name is based on a binary comparison, a
|
|
single built-in collating sequence that compares string data by
|
|
using the SQLite memcmp() function, regardless of text encoding.
|
|
See `Collating Sequences
|
|
<http://www.sqlite.org/datatype3.html#collation>`_.
|
|
|
|
Example requests and responses:
|
|
|
|
- Show account details and list containers and ask for a JSON
|
|
response:
|
|
|
|
::
|
|
|
|
curl -i $publicURL?format=json -X GET -H "X-Auth-Token: $token"
|
|
|
|
|
|
- List containers and ask for an XML response:
|
|
|
|
::
|
|
|
|
curl -i $publicURL?format=xml -X GET -H "X-Auth-Token: $token"
|
|
|
|
|
|
The response body returns a list of containers. The default
|
|
response (``text/plain``) returns one container per line.
|
|
|
|
If you use query parameters to page through a long list of
|
|
containers, you have reached the end of the list if the number of
|
|
items in the returned list is less than the request ``limit``
|
|
value. The list contains more items if the number of items in the
|
|
returned list equals the ``limit`` value.
|
|
|
|
When asking for a list of containers and there are none, the
|
|
response behavior changes depending on whether the request format
|
|
is text, JSON, or XML. For a text response, you get a 204 , because
|
|
there is no content. However, for a JSON or XML response, you get a
|
|
200 with content indicating an empty array.
|
|
|
|
If the request succeeds, the operation returns one of these status
|
|
codes:
|
|
|
|
- ``OK (200)``. Success. The response body lists the containers.
|
|
|
|
- ``No Content (204)``. Success. The response body shows no
|
|
containers. Either the account has no containers or you are
|
|
paging through a long list of names by using the ``marker``,
|
|
``limit``, or ``end_marker`` query parameter and you have reached
|
|
the end of the list.

Normal response codes: 200

Error response codes:204,

Create, update, or delete account metadata
|
|
==========================================
|
|
|
|
.. rest_method:: POST /v1/{account}
|
|
|
|
Creates, updates, or deletes account metadata.
|
|
|
|
To create, update, or delete custom metadata, use the
|
|
``X-Account-Meta-{name}`` request header, where ``{name}`` is the name of the
|
|
metadata item.
|
|
|
|
Account metadata operations work differently than how
|
|
object metadata operations work. Depending on the contents of your
|
|
POST account metadata request, the Object Storage API updates the
|
|
metadata as shown in the following table:
|
|
|
|
**Account metadata operations**
|
|
|
|
+----------------------------------------------------------+---------------------------------------------------------------+
|
|
| POST request header contains | Result |
|
|
+----------------------------------------------------------+---------------------------------------------------------------+
|
|
| A metadata key without a value. | The API removes the metadata item from the account. |
|
|
| | |
|
|
| The metadata key already exists for the account. | |
|
|
+----------------------------------------------------------+---------------------------------------------------------------+
|
|
| A metadata key without a value. | The API ignores the metadata key. |
|
|
| | |
|
|
| The metadata key does not already exist for the account. | |
|
|
+----------------------------------------------------------+---------------------------------------------------------------+
|
|
| A metadata key value. | The API updates the metadata key value for the account. |
|
|
| | |
|
|
| The metadata key already exists for the account. | |
|
|
+----------------------------------------------------------+---------------------------------------------------------------+
|
|
| A metadata key value. | The API adds the metadata key and value pair, or item, to the |
|
|
| | account. |
|
|
| The metadata key does not already exist for the account. | |
|
|
+----------------------------------------------------------+---------------------------------------------------------------+
|
|
| One or more account metadata items are omitted. | The API does not change the existing metadata items. |
|
|
| | |
|
|
| The metadata items already exist for the account. | |
|
|
+----------------------------------------------------------+---------------------------------------------------------------+
|
|
|
|
|
|
|
|
To delete a metadata header, send an empty value for that header,
|
|
such as for the ``X-Account-Meta-Book`` header. If the tool you use
|
|
to communicate with Object Storage, such as an older version of
|
|
cURL, does not support empty headers, send the ``X-Remove-Account-
|
|
Meta-{name}`` header with an arbitrary value. For example,
|
|
``X-Remove-Account-Meta-Book: x``. The operation ignores the arbitrary
|
|
value.
|
|
|
|
.. include:: metadata_header_syntax.inc
|
|
.. include:: metadata_header_encoding.inc
|
|
|
|
Subsequent requests for the same key and value pair overwrite the
|
|
existing value.
|
|
|
|
If the container already has other custom metadata items, a request
|
|
to create, update, or delete metadata does not affect those items.
|
|
|
|
This operation does not accept a request body.

Show account metadata
|
|
=====================
|
|
|
|
.. rest_method:: HEAD /v1/{account}
|
|
|
|
Shows metadata for an account.
|
|
|
|
Metadata for the account includes:
|
|
|
|
- Number of containers
|
|
|
|
- Number of objects
|
|
|
|
- Total number of bytes that are stored in Object Storage for the
|
|
account
|
|
|
|
Because the storage system can store large amounts of data, take
|
|
care when you represent the total bytes response as an integer;
|
|
when possible, convert it to a 64-bit unsigned integer if your
|
|
platform supports that primitive type.
|
|
|
|
Do not include metadata headers in this request.
