在canActivate上结束返回语句的问题

import { Injectable } from '@angular/core';
import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot } from '@angular/router';
import { Observable } from 'rxjs';

@Injectable()
export class AuthGuard implements CanActivate {
  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot): Observable<boolean> | Promise<boolean> | boolean {
    
    // 这里进行异步操作，比如验证用户权限或者从服务器获取验证结果
    return new Observable<boolean>(observer => {
      // 模拟异步操作
      setTimeout(() => {
        const isAuthenticated = // 根据业务逻辑进行验证
        observer.next(isAuthenticated); // 发送验证结果
        observer.complete(); // 完成Observable
      }, 1000);
    });
  }
}

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { AuthGuard } from './auth.guard';

const routes: Routes = [
  {
    path: 'protected',
    canActivate: [AuthGuard], // 使用AuthGuard进行权限验证
    loadChildren: () => import('./protected/protected.module').then(m => m.ProtectedModule)
  },
  // 其他路由配置...
];

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