Angular2:使用AuthGuard路由重定向

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

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

  canActivate(): boolean {
    // 进行身份验证和授权检查
    if (/* 用户已登录并具有访问权限 */) {
      return true; // 允许访问
    } else {
      this.router.navigate(['/login']); // 重定向到登录页面
      return false; // 不允许访问
    }
  }
}

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 { }
