    this.ponies = this.ponyService.getPonies(2);
  }
  refreshPonies() {
    this.ponies = this.ponyService.getPonies(3);
  }
}

服务:

import {Injectable} from "@angular/core";
import {Http} from "@angular/http";
import {Pony} from "../../models/pony.model";
@Injectable()
export class PonyService {
  constructor(private http: Http) {}
  getPonies(count: number): Array<Pony> {
    let toReturn: Array<Pony> = [];
    this.http.get('http://localhost:8080/js-backend/ponies')
    .subscribe(response => {
      response.json().forEach((tmp: Pony)=> …
