Can RouteData in Angular 2 pass variables to routed components from parent component?

I would like to use the RouteConfig to pass a variable from my AppComponent to Coursescomponent, but the "data" property in route config can only pass constant parameter, and it cannot recognize "this". Is there a way to do this?

If not, what is a best practice to pass variables to routed components?

@Component({
    selector: 'app',
    template: `
    <router-outlet></router-outlet>
    `,

directives: [ROUTER_DIRECTIVES],
})

@RouteConfig([
    { path: '/courses'
      , name: 'Courses' 
      ,component: CoursesComponent
       ,data:{token:this.token}}  // this doesn't work -- cannot read property "token" of undefined

])

export class AppComponent  {
    token:string;
//I would change the token(string) in this component, and I want to pass this to the routed components

}
