title: Get Heroes in Tour of Heroes from a REST url in Angular 2
body: <p>After the <a href="https://angular.io/docs/ts/latest/tutorial/" rel="nofollow">Angular 2 Tour of heroes tutorial</a>, I found myself wondering how I would "get the heroes" if I were using a REST api.</p>
  
  <p>Given that I have an API running on <code>http://localhost:7000/heroes</code> that would return the "mock-heroes" list of JSON, what is the minimum I need to do to make this "solid"?</p>
  
  <p>I'm as far as understanding I should put it in <code>hero.service.ts</code>; particularly in:</p>
  
  <pre><code>@Injectable()
  export class HeroService {
      getHeroes() {
          return Promise.resolve(HEROES);
      }
  }
  </code></pre>
  
  <p>But I'm stuck on how to do this at all using a http GET, let alone do it nicely/with style.</p>
