如何在angular中将请求组合到一个数组中？

import { forkJoin } from 'rxjs';

// 假设有三个请求的Observable
const request1$ = this.http.get('https://api.example.com/data1');
const request2$ = this.http.get('https://api.example.com/data2');
const request3$ = this.http.get('https://api.example.com/data3');

// 使用forkJoin将请求组合到一个数组中
forkJoin([request1$, request2$, request3$]).subscribe(
  ([response1, response2, response3]) => {
    // 在这里处理请求的结果
    console.log(response1);
    console.log(response2);
    console.log(response3);
  },
  error => {
    // 处理错误
    console.error(error);
  }
);
