如何在不使用HttpIntercepter的情况下在Angular中获取自定义响应头

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

constructor(private http: HttpClient) {}

getData() {
  return this.http.get('https://example.com/api/data');
}

getData() {
  this.http.get('https://example.com/api/data').subscribe(
    (response) => {
      // 处理响应数据
      console.log(response);

      // 获取自定义响应头
      const customHeader = response.headers.get('X-Custom-Header');
      console.log(customHeader);
    },
    (error) => {
      // 处理错误
      console.error(error);
    }
  );
}
