})
export class MyApp {
    rootPage: any = HomePage;

    constructor(platform: Platform) {
        platform.ready().then(() => {
            // Okay,so the platform is ready and our plugins are available.
            // Here you can do any higher level native things you might need.
            StatusBar.styleDefault();
        });
    }
}

home.ts

import {Page} from 'ionic-angular';
import {Component} from 'angular2/core';
import {AngularFire} from 'angularfire2';
import {Observable} from 'rxjs/Observable';

@Page({

您可以侦听这样的身份验证事件

ngOnInit() {

    // subscribe to the auth object to check for the login status
    // of the user,if logged in,save some user information and
    // execute the firebase query...
    // .. otherwise
    // show the login modal page
    this.auth.subscribe((data) => {
        console.log("in auth subscribe",data)
        if (data) {
            this.authInfo = data.password
            this.bookItems = this.af.list('/bookItems');
        } else {
            this.authInfo = null
            this.displayLoginModal()
        }
    })
}
