在Angular 10中:我可以刷新父路由的解析器中的数据吗？

@Injectable()
export class MyGuard implements CanActivate {
  constructor(private resolver: MyResolver) {}
  
  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean> {
    return this.resolver.resolve(route, state); // 重新调用解析器获取数据
  }
}

// 在路由配置中使用守卫
const routes: Routes = [
  {
    path: 'parent',
    component: ParentComponent,
    canActivate: [MyGuard],
    resolve: {
      data: MyResolver
    }
  }
];

import { ActivatedRoute, Router } from '@angular/router';

@Component({...})
export class MyComponent {
  constructor(private route: ActivatedRoute, private router: Router) {}

  refreshParentRoute(): void {
    const currentUrl = this.router.url;
    this.router.navigate([currentUrl], { queryParamsHandling: 'merge' });
  }
}

@Injectable({ providedIn: 'root' })
export class DataService {
  private dataSubject = new BehaviorSubject<any>(null);
  data$: Observable<any> = this.dataSubject.asObservable();

  setData(data: any): void {
    this.dataSubject.next(data);
  }
}

@Component({...})
export class ParentComponent {
  constructor(private dataService: DataService) {}

  refreshData(): void {
    // 调用解析器获取最新数据
    const newData = ...;
    this.dataService.setData(newData); // 更新共享服务中的数据
  }
}

@Component({...})
export class ChildComponent {
  constructor(private dataService: DataService) {}

  getData(): void {
    this.dataService.data$.subscribe(data => {
      // 获取最新的数据
    });
  }
}
