如何在Angular中使用JSON服务器获取json文件的最后一条记录？

npm install @angular/common@latest @angular/compiler@latest @angular/core@latest @angular/forms@latest @angular/platform-browser@latest @angular/platform-browser-dynamic@latest @angular/router@latest @angular/animations@latest @angular/http@latest

import { HttpClient } from '@angular/common/http';
import { Component } from '@angular/core';

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent {
  constructor(private http: HttpClient) { }
}

getLastRecordFromJson() {
  this.http.get('path/to/your/json/file.json').subscribe(data => {
    const lastRecord = data[data.length - 1];
    console.log(lastRecord);
  });
}
