如何从外部url获取数据种子id和所有给定的，而不是从我的应用程序(路由)在angular 6

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

constructor(private http: HttpClient) { }

getDataFromExternalUrl(url: string) {
  return this.http.get(url);
}

this.getDataFromExternalUrl('https://example.com/api/data').subscribe(
  (data: any) => {
    // 处理返回的数据
    console.log(data);
  },
  (error: any) => {
    // 处理错误
    console.error(error);
  }
);
