我试图从Angular中的服务接收布尔值，但它只返回整个对象

@Injectable()
export class MyService {
  getBooleanValue(): boolean {
    return true; // 这里返回你需要的布尔值
  }
}

@Component({
  selector: 'app-my-component',
  template: `
    <div>{{ booleanValue }}</div>
  `,
})
export class MyComponent implements OnInit {
  booleanValue: boolean;

  constructor(private myService: MyService) {}

  ngOnInit() {
    this.booleanValue = this.myService.getBooleanValue();
  }
}
