如何正确处理angular路由订阅，然后使用并行http请求的参数

import { Component, OnInit, OnDestroy } from '@angular/core';
import { Router, NavigationEnd } from '@angular/router';
import { HttpClient } from '@angular/common/http';
import { forkJoin, Subscription } from 'rxjs';
import { map } from 'rxjs/operators';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent implements OnInit, OnDestroy {
  private routerSubscription: Subscription;

  constructor(private router: Router, private http: HttpClient) { }

  ngOnInit() {
    this.routerSubscription = this.router.events.subscribe(event => {
      if (event instanceof NavigationEnd) {
        // 获取路由参数
        const params = this.router.routerState.root.firstChild.snapshot.params;

        // 发起并行的HTTP请求
        const request1 = this.http.get('api/endpoint1');
        const request2 = this.http.get('api/endpoint2');

        forkJoin([request1, request2]).pipe(
          map(([response1, response2]) => {
            // 处理HTTP请求的结果
            console.log(response1);
            console.log(response2);
          })
        ).subscribe();
      }
    });
  }

  ngOnDestroy() {
    this.routerSubscription.unsubscribe();
  }
}
