我必须将API json数据（嵌套对象响应）显示为ion-accordion。如何实现？下面是component.ts和service文件的代码
组件.ts代码：

import { Component, OnInit } from '@angular/core';
import { DataService } from '../data.service';
@Component({
  selector: 'app-view',
  templateUrl: './view.component.html',
  styleUrls: ['./view.component.scss']
})
export class ViewComponent implements OnInit {

  users: any = [];
  constructor(private userdata: DataService) { }

  ngOnInit() {
    this.userdata.get().subscribe(data =>{
      this.users = [data];
      console.log(this.users);
    });
  }

}

服务代码：

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) { }

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