如何在Angular canActivate guard中将父路由重定向到子路由？

import { Injectable } from '@angular/core';
import { CanActivate, Router, ActivatedRouteSnapshot } from '@angular/router';

@Injectable()
export class AuthGuard implements CanActivate {
  constructor(private router: Router) {}

  canActivate(route: ActivatedRouteSnapshot): boolean {
    // 检查是否满足重定向条件
    if (/* 满足条件 */) {
      this.router.navigate(['子路由路径'], { relativeTo: route });
      return false;
    }
    return true;
  }
}

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

const routes: Routes = [
  {
    path: '父路由路径',
    component: ParentComponent,
    canActivate: [AuthGuard],
    children: [
      {
        path: '子路由路径',
        component: ChildComponent
      }
    ]
  }
];

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