如何在app-routing.module.ts中定义带有查询参数的子页面的角度路由？

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { ParentComponent } from './parent.component';
import { ChildComponent } from './child.component';

const routes: Routes = [
  { path: 'parent', component: ParentComponent },
  { path: 'parent/child', component: ChildComponent },
];

const routes: Routes = [
  { path: 'parent', component: ParentComponent, 
    children: [
      { path: 'child', component: ChildComponent },
    ]
  },
];

const routes: Routes = [
  { path: 'parent', component: ParentComponent, 
    children: [
      { path: 'child', component: ChildComponent, 
        data: { queryParams: true }
      },
    ]
  },
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

<a [routerLink]="['/parent/child']" [queryParams]="{param1: 'value1', param2: 'value2'}">Go to Child Page</a>
