如何改进我的Angular组件，使我使用switchMap而不是链接多个订阅？

import { Component, OnInit } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { switchMap } from 'rxjs/operators';

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

  constructor(private http: HttpClient) { }

  ngOnInit(): void {
    this.getData().subscribe(result => {
      console.log(result);
      // 处理数据
    });
  }

  getData() {
    return this.http.get('https://api.example.com/data').pipe(
      switchMap(response => {
        // 在这里可以对响应数据进行处理
        return this.http.post('https://api.example.com/other-data', { data: response });
      })
    );
  }
}
