如何在NGRX中使用不同的参数触发相同的接口，并聚合响应？

import { Injectable } from '@angular/core';
import { Actions, createEffect, ofType } from '@ngrx/effects';
import { switchMap, map, mergeMap } from 'rxjs/operators';
import { HttpClient } from '@angular/common/http';

@Injectable()
export class MyEffects {
  myEffect$ = createEffect(() =>
    this.actions$.pipe(
      ofType('[MyFeature] Trigger Action'),
      switchMap((action) => {
        const params = action.params; // 获取参数值
        const requests = params.map((param) =>
          this.http.get(`api/myEndpoint/${param}`) // 调用相同的接口，传入不同的参数
        );
        return mergeMap(requests); // 聚合响应
      }),
      map((response) => ({
        type: '[MyFeature] Aggregated Response',
        payload: response,
      }))
    )
  );

  constructor(private actions$: Actions, private http: HttpClient) {}
}
