我正在尝试构建一个Glimmer组件，该组件可以对服务中的属性更改做出React，请参见下面的内容，我正在尝试使该组件更新get playing以响应audioPlayer url和状态的更改-当在下面的播放操作中按下播放按钮时，这些更改就会发生a a....这不起作用，而且我还没有找到任何文档来支持这种行为。

import { action } from '@ember/object';
import { inject as service } from '@ember/service'; 

export default class ShowAudioEpisodeComponent extends Component {

  @service audioPlayer;

  get playing() {
    return this.audioPlayer.url == this.args.epi.audioUrl && this.audioPlayer.status == "playing";
  }

  @action
  play() {
    if (this.playing) {
      this.audioPlayer.pause(this.args.epi);
    } else {
      this.audioPlayer.playEpisode(this.args.epi);
    }
  }

}
