export class FileDownloadService {

  constructor(private http: HttpClient) { }

  downloadFile(url: string): void {
    this.http.get(url, { responseType: 'blob' }).subscribe((data: Blob) => {
      const downloadUrl = window.URL.createObjectURL(data);
      const link = document.createElement('a');
      link.href = downloadUrl;
      link.download = 'filename.ext';
      link.click();

  constructor(private fileDownloadService: FileDownloadService) { }

  download(): void {
    const fileUrl = 'https://example.com/file.pdf'; // 替换为实际文件的URL地址
    this.fileDownloadService.downloadFile(fileUrl);
  }
}
