在angular 6中如何从服务中获取数据？

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

@Injectable({
  providedIn: 'root'
})
export class ServiceNameService {
  private apiUrl = 'https://api.example.com/data'; // 替换为实际的API地址

  constructor(private http: HttpClient) { }

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

import { Component, OnInit } from '@angular/core';
import { ServiceNameService } from '../service-name.service';

@Component({
  selector: 'app-component-name',
  templateUrl: './component-name.component.html',
  styleUrls: ['./component-name.component.css']
})
export class ComponentNameComponent implements OnInit {
  data: any;

  constructor(private serviceName: ServiceNameService) { }

  ngOnInit(): void {
    this.serviceName.getData().subscribe(data => {
      this.data = data;
      // 处理获取到的数据
    });
  }
}

<div>{{ data }}</div>
