How to make an API call in Angular 2?

There are lots of resources out there already but I haven't been able to find one that works for one reason or another. Take a generic example: I want to get the response from http://swapi.co/api/people, which will be a list of people from Star Wars.

import {Injectable } from '@angular/core';
import {Http, Response} from '@angular/http';
import {Observable} from 'rxjs/Observable';

import 'rxjs/add/operator/map';

@Injectable()
export class OombaDataService {
    constructor(private http: Http) {}
    private usersUrl = 'http://swapi.co/api/people/';

getData() {
    retu this.http.get(this.usersUrl)
    .map(this.extractData)
}

private extractData(res: Response) {
    let body = res.json();
    retu body.data || { };
}
private handleError (error: any) {
// In a real world app, we might use a remote logging infrastructure
// We'd also dig deeper into the error to get a better message
let errMsg = (error.message) ? error.message :
error.status ? `${error.status} - ${error.statusText}` : 'Server error';
console.error(errMsg); // log to console instead
retu Observable.throw(errMsg);
}
}

A lot of this should be correct since it's based on Angular's own tutorial on the matter. But for whatever reason, when I call it in my components, it just retus an observable object without the JSON data. What am I missing? The team and I have been stuck on this for a while. :P Thanks!
