The authentication request returns X-Storage-Url and X-Auth-Token
headers. For the JS client to see them they need to be referenced in
Access-Control-Expose-Headers. As of the last time checked, both these
headers were being stripped from the response before being presented
to JS.

Hi Adrian,
Good to know this is a known issue.
Why does the client need to see custom headers from the server anyway?
I know the client needs to pass the authorisation header to the server, but
I haven't seen any of the APIs yet that return custom headers. (It's likely
I'm missing them though)

Hi Nick,
I did some work with CORS a few months back [1].
At the time I couldn't get any browser to work properly with CORS so I
just parked the code. The problem was lack of support for the
Access-Control-Expose-Headers header.
According to the Chrome bug report [2] this issue may well be fixed
now so I need to retest.

Hi,
I've been playing with the Nova APIs from Javascript, and I've run into
a
problem.
The very first thing one needs to do to use the APIs is to get a token.
That requires a POST to the API endpoint. Using curl& trystack that
looks
like this:
$ curl -k -X 'POST' -v https://nova-api.trystack.org:5443/v2.0/tokens -d
'{"auth":{"passwordCredentials":{"username": "<username>",
"password":"<password>"}}}' -H 'Content-type: application/json'
The Javascript equivalent (using JQuery) is:
$.ajax({
url: "https://nova-api.trystack.org:5443/v2.0/tokens";,
type: 'POST',
headers: {"Content-Type": "application/json"},
data: {"auth":{"passwordCredentials":{"username":"<username>",
"password":"<password>"}}},
success: function(data) { alert(data); }
});
That fails because the call is cross-domain, and Nova doesn't support
CORS
(http://en.wikipedia.org/wiki/Cross-origin_resource_sharing).<script>
based
cross-domain requests only supports GET requests, so that doesn't work
either.
I have raised a bug: https://bugs.launchpad.net/nova/+bug/987044, but
I'm
really hoping someone can point out something obvious I'm missing here.
Regards
Nick Lothian
