You can create an Injectable for this and use this class instead of the angular http class. Here you filter the links and than call http with the right link.

@Injectable() 
export class Hypermedia {

   constructor(private http: Http) { }

   get(links: any[], rel: String, body?: any, options?: RequestOptionsArgs): Observable {
    var link = null;
    var request = null;

    // Find the right link
    links.forEach(function (_link) {
        if (_link.rel === rel) {
            link = _link
            return;
        }
    });

    return this.http.get(link.href);
}

}

Provide this injector and add it to the constructor where you need it

constructor(private hypermedia:Hypermedia)

Then you can simply call it like you normally would call the http class

this.hypermedia.get(myHypermediaLinksArray,myRel)

Hope this helps:)
