隐式回调重定向到Angular组件，然后自动重定向到主页

import { Injectable } from '@angular/core';
import { CanActivate, Router } from '@angular/router';

@Injectable()
export class AuthGuard implements CanActivate {
  constructor(private router: Router) {}

  canActivate(): boolean {
    // 在这里检查用户的登录状态或权限
    const isAuthenticated = ...; // 检查用户是否已登录

    if (isAuthenticated) {
      // 用户已登录，允许导航
      return true;
    } else {
      // 用户未登录，重定向到主页
      this.router.navigate(['/home']);
      return false;
    }
  }
}

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

const routes: Routes = [
  { path: '', redirectTo: '/callback', pathMatch: 'full' },
  { path: 'callback', component: CallbackComponent, canActivate: [AuthGuard] },
  { path: 'home', component: HomeComponent }
];

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