无法将web api中的数据绑定到Angular中的选择选项

import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class DataService {
  constructor(private http: HttpClient) { }

  getOptions(): Observable<any> {
    return this.http.get<any>('api/your-data-endpoint');
  }
}

import { Component, OnInit } from '@angular/core';
import { DataService } from 'your-data-service';

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent implements OnInit {
  options: any[];

  constructor(private dataService: DataService) { }

  ngOnInit(): void {
    this.dataService.getOptions().subscribe(data => {
      this.options = data;
    });
  }
}

<select>
  <option *ngFor="let option of options" [value]="option.value">{{ option.label }}</option>
</select>
