我希望angular能够访问URL并获取STL文件，该文件可供进一步处理时重用

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

@Injectable()
export class FileService {
  constructor(private http: HttpClient) { }

  getFile(url: string): Observable<any> {
    return this.http.get(url);
  }
}

import { Component } from '@angular/core';
import { FileService } from './file.service';

@Component({
  selector: 'app-file',
  template: `
    <button (click)="getFile()">获取文件</button>
    <div>{{ fileData }}</div>
  `,
})
export class FileComponent {
  fileData: any;

  constructor(private fileService: FileService) { }

  getFile() {
    const url = 'https://example.com/file.stl'; // 替换为实际的文件URL
    this.fileService.getFile(url).subscribe(data => {
      this.fileData = data;
      // 进一步处理文件数据
    });
  }
}
