I have a question regarding the Tuleap REST API when used with CORS.
Basically, I'm trying to make a REST call to see the backlog of my project.
Referring to the API Explorer, to do so I need to do a GET call like this: /api/projects/{id}/backlog I also need to add the custom headers X-Auth-Token and X-Auth-UserId to ensure the authentication.
When I do this request with a HTTP Request tool (Poster for Firefox) everything works fine and I get status 200.
The problem now is that I'm trying to develop an application (in angularJS) that would do the same request.
I noticed that when the page is doing the request, it starts by doing a preflight OPTIONS request which is due to the Cross-Origin-Ressource-Sharing.
It seems like the X-Auth-Token and X-Auth-UserId header are being put in the Access-Control-Request-Headers. Because of that I get an unauthorized 401 response code from the server and I can't complete the request.
I've been looking online and couldn't find my answer as how to make this call work.
There was a recent contribution that should remove the need for authentication on all OPTIONS routes in order to enable the preflight: http://gerrit.tuleap.net/#/c/2642/ It was Integrated in Tuleap 7.2.99.36 Either your version of Tuleap is too old or there is a bug.
Note all calls still require some headers such as "Content-Type: application/json"; the integration tests should provide good examples of how to make calls:
