如何在ionic2浏览器刷新时导航到当前页面本身？

npm install @angular/router --save

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouterModule, Router } from '@angular/router';

import { MyApp } from './app.component';

@NgModule({
  declarations: [
    MyApp
  ],
  imports: [
    BrowserModule,
    RouterModule.forRoot([])
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp
  ],
  providers: []
})
export class AppModule {
  constructor(private router: Router) {
    this.router.initialNavigation(); // 初始化导航
  }
}

import { Component, OnInit } from '@angular/core';
import { Router } from '@angular/router';

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html'
})
export class AppComponent implements OnInit {
  constructor(private router: Router) {}

  ngOnInit() {
    this.router.navigate(['']); // 导航到当前页面
  }
}
