access-control-allow-origin on playframework

问题

How can I get playframework to allow non-origin calls? I have tried adding a @Before method to a controller, but that never gets called by an ajax client.

@Before 
public static void setCORS()
{
    Http.Response.current().accessControl("*", "GET,PUT,POST,DELETE", true);
}

I am trying to setup a test API server for client developers to test against, but that seems to require disabling the Origin restriction.

Has anyone else got this working? or accomplished this in a different way?

UPDATE: I found this article on the topic http://javathought.wordpress.com/2011/12/04/cross-origin-resource-sharing-with-play-framework/

回答1:

Check what your browser is trying to do, it may send an OPTION request first to check what is allowed, this is called "preflight request".

Also, setting Access-Control-Allow-Origin to * only works without credentials.

Using a custom router can solve this.

For example using: https://github.com/teamon/play-navigator

val rget = GET on "foo" to App.foo
val gpost = POST on "foo" to App.foo
