Angular 2路由不区分大小写

Question

我从他们的文档中跟随角度2教程，但我遇到了关于他们的路由的问题。如何使其不区分大小写？

以下是angular 2 docs的路由代码

import { NgModule }             from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { DashboardComponent }   from './dashboard.component';
import { HeroesComponent }      from './heroes.component';
import { HeroDetailComponent }  from './hero-detail.component';

const routes: Routes = [
  { path: '', redirectTo: '/dashboard', pathMatch: 'full' },
  { path: 'dashboard',  component: DashboardComponent },
  { path: 'detail/:id', component: HeroDetailComponent },
  { path: 'heroes',     component: HeroesComponent }
];

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