如何从angular 6中的示例json动态呈现ul li值

{
  "items": [
    {
      "id": 1,
      "name": "Item 1"
    },
    {
      "id": 2,
      "name": "Item 2"
    },
    {
      "id": 3,
      "name": "Item 3"
    }
  ]
}

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

@Injectable({
  providedIn: 'root'
})
export class DataService {
  private dataUrl = 'assets/data.json';

  constructor(private http: HttpClient) { }

  getData(): Observable<any> {
    return this.http.get<any>(this.dataUrl);
  }
}

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

@Component({
  selector: 'app-example',
  template: `
    <ul>
      <li *ngFor="let item of items">{{ item.name }}</li>
    </ul>
  `
})
export class ExampleComponent implements OnInit {
  items: any[];

  constructor(private dataService: DataService) { }

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