如何在PrimeNG的下拉输入字段中显示来自api的一些值

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

@Component({
  selector: 'app-dropdown-example',
  templateUrl: './dropdown-example.component.html',
  styleUrls: ['./dropdown-example.component.css']
})
export class DropdownExampleComponent implements OnInit {
  apiData: any[]; // 用于存储API返回的数据

  constructor(private http: HttpClient) { }

  ngOnInit(): void {
    this.http.get<any[]>('https://api.example.com/data') // 替换为你的API URL
      .subscribe(data => {
        this.apiData = data; // 将API返回的数据赋值给变量
      });
  }
}

<p-dropdown [options]="apiData" [(ngModel)]="selectedValue" optionLabel="label"></p-dropdown>
