Answer 1

Youll want to use the map operator:

@Injectable()
export class ItemTest {

    constructor(private _http: HttpClient) {}

    getItems(): Observable {
        return this._http.get('url').map((data) => data['d']['results'])              
            .do(data => {
                console.log(data);
            })
    }
}
