当前角度为2 rc 6的路由器状态事件

Question

似乎在角度2 rc 6中删除了OnActivate，对此有什么选择。

我需要有一个方法，当为特定路由传递的所有canActivate方法都发生变化时，这个方法也应该能够接受保留导航的承诺。

class UserToken {}
class Permissions {
  canActivate(user: UserToken, id: string): boolean {
    return true;
  }
}
@Injectable()
class CanActivateTeam implements CanActivate {
  constructor(private permissions: Permissions, private currentUser: UserToken) {}
  canActivate(
    route: ActivatedRouteSnapshot,
    state: RouterStateSnapshot
  ): Observable<boolean>|Promise<boolean>|boolean {
    return this.permissions.canActivate(this.currentUser, route.params.id);
  }
}
@NgModule({
  imports: [
    RouterModule.forRoot([
      {
        path: 'team/:id',
        component: TeamCmp,
        canActivate: [CanActivateTeam]
      }
    ])
  ],
  providers: [CanActivateTeam, UserToken, Permissions]
})
class AppModule {}
