Angular 2. How to handle 4xx errors with redirect in Observable?

Question

I have a service that calls an api

getItems(itemId: number): Observable {
    return this.http.get(url, headers)
        .map(this.extractDataSing         


        

Answer 1

I guess this does what you want:

private handleError = (error: any) => {
   this._router.navigate(['Login']);
   return Observable.of([]);
}
