How to get query params from url in Angular 2?

I use angular2.0.0-beta.7. When a component is loaded on a path like /path?query=value1 it is redirected to /path. Why were the GET params removed? How can I preserve the parameters?

I have an error in the routers. If I have a main route like

@RouteConfig([
  {
      path: '/todos/...',
      name: 'TodoMain',
      component: TodoMainComponent
  }
])

and my child route like

@RouteConfig([
  { path: "https://stackoverflow.com/", component: TodoListComponent, name: 'TodoList', useAsDefault:true },
  { path: '/:id', component: TodoDetailComponent, name:'TodoDetail' }
])

then I can’t get params in TodoListComponent. I am able to get

params("/my/path;param1=value1;param2=value2") 

but I want the classic

query params("/my/path?param1=value1&param2=value2")
