无法从Ionic中的登录页面路由到菜单页面

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { LoginPage } from './pages/login/login.page';
import { MenuPage } from './pages/menu/menu.page';

const routes: Routes = [
  {
    path: '',
    redirectTo: 'login',
    pathMatch: 'full'
  },
  {
    path: 'login',
    component: LoginPage
  },
  {
    path: 'menu',
    component: MenuPage
  }
];

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

import { Router } from '@angular/router';

...

constructor(private router: Router) { }

...

login() {
  // 登录成功后进行路由跳转到菜单页面
  this.router.navigateByUrl('/menu');
}
