在Angular中使用CanActivate保护的多个通配符路由

import { Injectable } from '@angular/core';
import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot, UrlTree, Router } from '@angular/router';
import { Observable } from 'rxjs';
import { AuthService } from './auth.service';

@Injectable({
  providedIn: 'root'
})
export class AuthGuard implements CanActivate {
  constructor(private authService: AuthService, private router: Router) {}

  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot): Observable<boolean | UrlTree> | Promise<boolean | UrlTree> | boolean | UrlTree {
    if (this.authService.isLoggedIn()) {
      // 用户已登录，允许访问受保护的路由
      return true;
    } else {
      // 用户未登录，重定向到登录页面
      this.router.navigate(['/login']);
      return false;
    }
  }
}

const routes: Routes = [
  { path: 'admin', component: AdminComponent, canActivate: [AuthGuard] },
  { path: 'user', component: UserComponent, canActivate: [AuthGuard] },
  { path: '**', component: NotFoundComponent }
];
