Backbone with laravel as an api not returning error

Question

I created an simple Backbone script wich relies on a simple api created with laravel RESTful capabilities. The html containing Backbone script resides on my desktop and the server api on my xampp localhost.

on Laravel :

/**
 * Display the specified resource.
 *
 * @param  int  $id
 * @return Response
 */
public function show($id)
{
    $task = Task::find($id);

            return $task;
}

on Backbone :

(function(){

 App = {

  Models : {},

  Views : {},

  Collections : {}

 }; 

 App.Models.Task = Backbone.Model.extend({

  defaults : {title : '', active : 0},

  urlRoot : 'http://localhost/api/public/tasks'

 });

  var task = new App.Models.Task({id : 1});

  task.fetch();

  //task.set({title : 'new tite', active : 1});

  //task.save();

})();

The server side seams to be ok, cause on testing returns the proper json object, but when i try to run the Backbone script i get this error in dev console :

> XMLHttpRequest cannot load http://localhost/api/public/tasks/1. No
> 'Access-Control-Allow-Origin' header is present on the requested
> resource. Origin 'null' is therefore not allowed access

. What could be the problem ???

Sounds like you have two different domains, one for the backbone page and another for the laravel api. You could either make sure they run on the same domain or [see this question for setting the origin headers](http://stackoverflow.com/questions/1653308). — Jonathan Beebe, Mar 01 '14 at 03:10

Maybe someone will need this !

Thank's to TonyArra I found the answer:

since the server and the request script was on 2 different domains here is the solution:

add this on server (using laravel i added this code in the constructor of the restful controller):

        $http_origin = $_SERVER['HTTP_ORIGIN'];

       //if you trust origin set header else verify source

       //if ($http_origin == "http://www.domain1.com")

       header("Access-Control-Allow-Origin: $http_origin");
