Angular路由在页面刷新时重定向到父路由而不是子路由

// app-routing.module.ts
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { ParentComponent } from './parent.component';

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

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

// parent.component.ts
import { Component, OnInit } from '@angular/core';
import { Router } from '@angular/router';

@Component({
  selector: 'app-parent',
  template: `
    <h1>Parent Component</h1>
    <router-outlet></router-outlet>
  `,
})
export class ParentComponent implements OnInit {
  constructor(private router: Router) {}

  ngOnInit() {
    this.router.navigate(['parent']);
  }
}

// child.component.ts
import { Component } from '@angular/core';

@Component({
  selector: 'app-child',
  template: `
    <h2>Child Component</h2>
  `,
})
export class ChildComponent {}
