在angular2中呈现编辑表单。如何等待来自服务的数据？

// data.service.ts
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';

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

  getData(): Observable<any> {
    return this.http.get('api/data'); // 替换为实际的数据获取接口
  }
}

// component.ts
import { Component, OnInit } from '@angular/core';
import { DataService } from './data.service';

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

  constructor(private dataService: DataService) {}

  ngOnInit() {
    this.dataService.getData().subscribe(
      (response) => {
        this.data = response;
      },
      (error) => {
        console.error(error);
      }
    );
  }
}

// component.html
<div *ngIf="data">
  <!-- 在这里呈现编辑表单 -->
</div>
