Angular 2 RC4路由保护服务注入

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

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

  canActivate(): boolean {
    // 在这里进行身份验证和授权检查
    // 如果用户未经授权，则重定向到登录页面
    if (!isAuthorized) {
      this.router.navigate(['/login']);
      return false;
    }
    return true;
  }
}

import { Routes, RouterModule } from '@angular/router';

const routes: Routes = [
  { path: 'admin', component: AdminComponent, canActivate: [AuthGuard] },
  // 其他路由配置...
];

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