Return beobachtbar aus Funktion Angular
1. Better practise is to use Observable:
import { catchError } from 'rxjs/operators';
import { throwError } from 'rxjs';
bbb() {
return this.http.get(this.url)
.pipe(
catchError(err => {
console.log('err', err);
return throwError('Something bad happened; please try again later.');
});
}
2. And, then simply just subscribe to bbb:
import { Subscription } from 'rxjs';
testSubscription: Subscription;
ngAfterContentInit() {
this.testSubscription = this.bbb()
.subscribe(son => {
console.log('son', son); // here you get the result
});
}
3. Don't forget to unsubscribe:
ngOnDestroy() {
this.testSubscription.unsubscribe();
}
