在Ionic 2中使用AngularFire2查询Firebase数据

npm install -g ionic
npm install firebase @angular/fire

import { Injectable } from '@angular/core';
import { AngularFireDatabase } from '@angular/fire/database';

@Injectable()
export class FirebaseService {
  constructor(private db: AngularFireDatabase) {}

  getData() {
    return this.db.list('data').valueChanges();
  }
}

import { Component } from '@angular/core';
import { FirebaseService } from '../firebase.service';

@Component({
  selector: 'app-home',
  templateUrl: 'home.page.html',
  styleUrls: ['home.page.scss'],
})
export class HomePage {
  data: any[];

  constructor(private firebaseService: FirebaseService) {}

  ngOnInit() {
    this.firebaseService.getData().subscribe((data) => {
      this.data = data;
    });
  }
}

<ion-content>
  <ion-list>
    <ion-item *ngFor="let item of data">
      {{ item.name }}
    </ion-item>
  </ion-list>
</ion-content>
