Angular2路由器CanActivate，带参数？

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

@Injectable()
export class AuthGuard implements CanActivate {
  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
    // 获取传递的参数
    const param = route.params['paramName'];
    
    // 进行权限验证或其他操作
    if (param === 'admin') {
      return true; // 允许访问
    } else {
      return false; // 禁止访问
    }
  }
}

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

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

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