在angular7中，如何从两个不同的相关http调用中获得组合响应。第一个http调用返回对象及其相关数据的数组

import { forkJoin, Observable } from 'rxjs';
import { HttpClient } from '@angular/common/http';
import { map } from 'rxjs/operators';

// 在组件中使用forkJoin进行HTTP请求的组合
export class YourComponent {
  constructor(private http: HttpClient) {}

  public getData(): Observable<any> {
    const request1$ = this.http.get('url1');
    const request2$ = this.http.get('url2');

    return forkJoin([request1$, request2$]).pipe(
      map(([response1, response2]) => {
        // 对响应进行处理
        const combinedResponse = {
          response1: response1,
          response2: response2
        };
        return combinedResponse;
      })
    );
  }
}
