如何在spring boot中检索url并在Angular中使用？

@RestController
@RequestMapping("/api")
public class UrlController {

    @GetMapping("/url")
    public String getUrlData() {
        // 使用RestTemplate或WebClient发送HTTP请求并获取URL的数据
        RestTemplate restTemplate = new RestTemplate();
        String url = "https://example.com"; // 要检索的URL
        ResponseEntity<String> response = restTemplate.getForEntity(url, String.class);
        return response.getBody();
    }
}

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

@Injectable({
  providedIn: 'root'
})
export class UrlService {

  constructor(private http: HttpClient) { }

  getUrlData() {
    const url = '/api/url'; // 调用Spring Boot的接口
    return this.http.get(url);
  }
}

@Component({
  selector: 'app-url',
  templateUrl: './url.component.html',
  styleUrls: ['./url.component.css']
})
export class UrlComponent implements OnInit {

  urlData: string;

  constructor(private urlService: UrlService) { }

  ngOnInit() {
    this.urlService.getUrlData().subscribe(data => {
      this.urlData = data; // 将获取到的数据绑定到前端页面上
    });
  }
}
