读取来自asp.net内核的blob数据到Angular 7

import { Component } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { saveAs } from 'file-saver';

@Component({
  selector: 'app-blob-reader',
  templateUrl: './blob-reader.component.html',
  styleUrls: ['./blob-reader.component.css']
})
export class BlobReaderComponent {
  constructor(private http: HttpClient) { }

  downloadBlobData() {
    const headers = new HttpHeaders().set('Accept', 'application/octet-stream');
    this.http.get('http://your-api-endpoint', { headers, responseType: 'blob' })
      .subscribe(response => {
        const blob = new Blob([response], { type: 'application/octet-stream' });
        saveAs(blob, 'filename.ext');
      });
  }
}
