Hi Arief! If I understood your question correctly, I think you will need to use the SystemXHR API[1] and permission[2] to accomplish that in general. This is due to (in this regard) your app is trying to access "external" content - that is, it is accessing cross-origin resources via XMLHttpRequest, which is (most of the time) forbidden. The SystemXHR permission and property lets your app execute XHR request without being limited by this origin-checking.
A possible workaround for the above problem might be (and quite a few websites/services who have publicly accessible API-s already do this) is to make requests to online resources which support the CORS scheme (Cross-origin resource sharing)[3], in which (if you have access to the server-side) you can control from which origins your "service" could be accessed, and thus queried by XHR also. Hope to have answered your question, if not, feel free to elaborate. Happy hacking!
