如何从angular服务向propublica.org发出web api调用

npm install @angular/common/http

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

constructor(private http: HttpClient) { }

getPropublicaData(): Observable<any> {
  const url = 'https://api.propublica.org/data/v1/example'; // 替换为实际的API端点
  const headers = {
    'X-API-Key': 'YOUR_API_KEY' // 替换为你的API密钥
  };

  return this.http.get(url, { headers });
}

import { Component, OnInit } from '@angular/core';
import { YourService } from 'path/to/your/service';

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent implements OnInit {
  data: any;

  constructor(private yourService: YourService) { }

  ngOnInit(): void {
    this.yourService.getPropublicaData().subscribe(
      (response) => {
        this.data = response;
        // 处理返回的数据
      },
      (error) => {
        console.error(error);
        // 处理错误
      }
    );
  }
}
