如何用angular 2设置头部cookie

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

constructor(private http: HttpClient) { }

setCookie() {
  const headers = new HttpHeaders().set('Cookie', 'cookie_name=cookie_value');
  // 可以设置多个cookie，使用分号分隔，例如：'cookie1_name=cookie1_value; cookie2_name=cookie2_value'

  // 发送一个GET请求，将cookie头部包含在请求中
  this.http.get('https://example.com/api', { headers }).subscribe(response => {
    console.log(response);
  });
}

this.setCookie();
