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

@Injectable({
  providedIn: 'root'
})
export class AuthGuard implements CanActivate {
  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot): Observable<boolean | UrlTree> | Promise<boolean | UrlTree> | boolean | UrlTree {
    // 在这里进行身份验证逻辑判断
    // 如果用户已登录，返回true，允许访问路由
    // 如果用户未登录，返回false或重定向到登录页面
    return true;
  }
}

// app-routing.module.ts
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home.component';
import { ProfileComponent } from './profile.component';
import { AuthGuard } from './auth.guard';

const routes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'profile', component: ProfileComponent, canActivate: [AuthGuard] }
];

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