将OpenID支持添加到Play Framework应用程序时如何调用absoluteURL（）？

Question

I am attempting to add OpenID login support to a Play Framework application using the sample code on the documentation page :

Map<String, String> attributes = new HashMap<String, String>();
attributes.put("email", "http://schema.openid.net/contact/email");
OpenID.redirectURL(
  openid, 
  routes.Application.openIDCallback.absoluteURL(), 
  attributes
);

The problem is that when I use this code, I get the following compilation error:

cannot find symbol [symbol: method absoluteURL()] [location: class play.api.mvc.Call]

Indeed, there isn't a no-argument absoluteURL() method of the Call class; the Call#absoluteURL() methods are:

absoluteURL(Http.Request request)

and:

absoluteURL(Http.Request request, boolean secure)

What Http.Request instance do I need to use? What is the significance of the secure parameter?

Try with the current request:

Map<String, String> attributes = new HashMap<String, String>();
attributes.put("email", "http://schema.openid.net/contact/email");
OpenID.redirectURL(
  openid, 
  routes.Application.openIDCallback.absoluteURL(request()), 
  attributes
);
