在post请求中使用带有map的ForkJoin - angular 8

import { Component } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { forkJoin } from 'rxjs';

@Component({
  selector: 'app-post',
  templateUrl: './post.component.html',
  styleUrls: ['./post.component.css']
})
export class PostComponent {

  constructor(private http: HttpClient) { }

  postData() {
    const requestBody1 = { key1: 'value1' };
    const requestBody2 = { key2: 'value2' };

    const request1 = this.http.post('http://example.com/api/endpoint1', requestBody1);
    const request2 = this.http.post('http://example.com/api/endpoint2', requestBody2);

    forkJoin([request1, request2]).subscribe(responses => {
      // 处理响应数据
      const response1 = responses[0];
      const response2 = responses[1];
      console.log(response1, response2);
    });
  }
}
