As mentioned by Milad in his answer, since Observables returned by Http's methods are cold/lazy and won't fire until you subscribe to them.

But let's say what if you don't want to .subscribe to the Observable but still want the HTTP request to fire?

In case you're using Angular 6 with Rxjs6 and don't want to subscribe , you can do the following:

...
import { publish } from 'rxjs/operators';
import { HttpClient } from '@angular/common/http';

constructor(private http: HttpClient) {}

getAllPersons() {
  const getAllPersons$ = this.http.get(`https://swapi.co/api/people/1`)
    .pipe(
        publish()
      );

  getAllPersons$.connect();
}
