我生成了一个JSON文件，并将其添加到我的一个提供程序“people.ts”中：

getPeople(): Observable<any> {
    return this.http.get("https://randomuser.me/api/?results=10")
}

然后我写了2个函数，它们应该在调用后重新加载并添加更多JSON对象（ionic infinite scroll和doRefresh函数）如下：

constructor(public navCtrl: NavController,
              public service: People)
  {
    this.service.getPeople().subscribe( data => {
      this.people = data.results
    });
  }

  doRefresh(e) {
    this.service.getPeople()
    this.service.getPeople().subscribe( data => {
      this.people.unshift(...data.results),
        Error => console.log(Error),
        () => e.complete()
    });
  }
  doInfinite(e) {
    this.service.getPeople()
    this.service.getPeople().subscribe( data => {
      this.people.push(...data.results),
        Error => console.log(Error),
        () => e.complete()
    });
  }

问题是两者都只工作一次（它们刷新和添加），循环从未停止旋转。我该怎么办？

我就是这么称呼他们的：

<ion-refresher (ionRefresh)="doRefresh($event)">
    <ion-refresher-content>

    </ion-refresher-content>
  </ion-refresher>

  <ion-infinite-scroll (ionInfinite)="doInfinite($event)">
    <ion-infinite-scroll-content>

    </ion-infinite-scroll-content>
  </ion-infinite-scroll>
