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

@Injectable({
  providedIn: 'root'
})
export class DataService {
  private jsonUrl = 'https://example.com/data.json'; // JSON数据的URL地址

  constructor(private http: HttpClient) { }

  getJsonData(): Observable<any> {
    return this.http.get<any>(this.jsonUrl);
  }
}

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

@Component({
  selector: 'app-root',
  template: `
    <div *ngFor="let item of jsonData">{{ item.name }}</div>
  `
})
export class AppComponent {
  jsonData: any[];

  constructor(private dataService: DataService) { }

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