By default, the Object Storage API uses a
text/plain
response format. In
addition, both JSON and XML data serialization response
formats are supported.

To define the response format, use one of these methods:

Example 1.1. JSON example with format query parameter
For example, this request uses the
format
query parameter to ask
for a JSON response:
# curl -i $publicURL?format=json -X GET -H "X-Auth-Token: $token"
HTTP/1.1 200 OK Content-Length: 96 X-Account-Object-Count: 1 X-Timestamp: 1389453423.35964 X-Account-Meta-Subject: Literature X-Account-Bytes-Used: 14 X-Account-Container-Count: 2 Content-Type: application/json; charset=utf-8 Accept-Ranges: bytes X-Trans-Id: tx274a77a8975c4a66aeb24-0052d95365 Date: Fri, 17 Jan 2014 15:59:33 GMT
Object Storage lists container names with additional information in JSON format:
[ { "count":0, "bytes":0, "name":"janeausten" }, { "count":1, "bytes":14, "name":"marktwain" } ]
Example 1.2. XML example with Accept header
This request uses the Accept
request
header to ask for an XML response:
# curl -i $publicURL -X GET -H "X-Auth-Token: $token" -H "Accept: application/xml; charset=utf-8"
HTTP/1.1 200 OK Content-Length: 263 X-Account-Object-Count: 3 X-Account-Meta-Book: MobyDick X-Timestamp: 1389453423.35964 X-Account-Bytes-Used: 47 X-Account-Container-Count: 2 Content-Type: application/xml; charset=utf-8 Accept-Ranges: bytes X-Trans-Id: txf0b4c9727c3e491694019-0052e03420 Date: Wed, 22 Jan 2014 21:12:00 GMT
Object Storage lists container names with additional information in XML format:
<?xml version="1.0" encoding="UTF-8"?> <account name="AUTH_73f0aa26640f4971864919d0eb0f0880"> <container> <name>janeausten</name> <count>2</count> <bytes>33</bytes> </container> <container> <name>marktwain</name> <count>1</count> <bytes>14</bytes> </container> </account>
The remainder of the examples in this guide use
standard, non-serialized responses. However, all GET
requests that perform list operations accept the
format
query parameter or
Accept
request header.
