访问Ionic 3中的复杂json对象并绑定到视图

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class DataService {

  constructor(private http: HttpClient) { }

  getJSONData(): Observable<any> {
    return this.http.get<any>('assets/data.json');
  }
}

import { Component, OnInit } from '@angular/core';
import { DataService } from '../services/data.service';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.scss']
})
export class MyComponent implements OnInit {
  jsonData: any;

  constructor(private dataService: DataService) { }

  ngOnInit() {
    this.dataService.getJSONData().subscribe(data => {
      this.jsonData = data;
    });
  }
}

<ul>
  <li *ngFor="let item of jsonData.items">{{ item.name }}</li>
</ul>
