How to hang an event handler on each NavigationEnd event in Angular?

Question

Angular

Right now I'm handling each event like this:

ngOnInit() {
    this.router.events.subscribe((event: any) => {
      if (event.error) {
        this.router.navigate(['/login']);
      }
      if (event instanceof NavigationEnd) {
        console.log(event);
        console.log(this);
      }
    });

The question is how do I get the right response header?
This contains ActivatedRoute and Router, maybe you can do it somehow with the help of them?
