从json文件中获取数据到Angular ts中

  "name": "John Doe",
  "age": 25,
  "email": "johndoe@example.com"
}

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

  constructor(private http: HttpClient) { }

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

import { Component, OnInit } from '@angular/core';

})
