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: ':gymId/dashboard', component: DashboardComponent },
  { path: ':gymId/profile', component: ProfileComponent },
  // 其他路由...
];

@Injectable({
  providedIn: 'root'
})
export class GymIdGuard implements CanActivate {
  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
    const gymId = route.paramMap.get('gymId');
    if (!gymId) {
      // 如果没有提供gymId，重定向到错误页面或登录页面
      this.router.navigate(['/error']);
      return false;
    }
    // 可以在这里添加更多的验证逻辑
    return true;
  }

  constructor(private router: Router) {}
}

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

const routes: Routes = [
  // ...其他路由
  { path: '**', redirectTo: '/error' }
];
