Angular 7 Routing -如何确保所有路由都使用:gymId参数作为前缀

const routes: Routes = [
  { path: 'gym/:gymId/dashboard', component: DashboardComponent },
  { path: 'gym/:gymId/profile', component: ProfileComponent },
  // 其他路由配置项...
];

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

import { Component, OnInit } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({
  selector: 'app-dashboard',
  templateUrl: './dashboard.component.html',
  styleUrls: ['./dashboard.component.css']
})
export class DashboardComponent implements OnInit {
  gymId: string;

  constructor(private route: ActivatedRoute) { }

  ngOnInit() {
    this.gymId = this.route.snapshot.paramMap.get('gymId');
  }
}

import { Component } from '@angular/core';
import { Router } from '@angular/router';

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css']
})
export class HomeComponent {
  constructor(private router: Router) { }

  navigateToDashboard(gymId: string) {
    this.router.navigate(['/gym', gymId, 'dashboard']);
  }
}
