如何调用与此jquery等效的角度http post

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

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

constructor(private http: HttpClient) { }

postData() {
  const url = 'https://example.com/api/endpoint'; // 替换为你的API端点URL
  const data = { key1: 'value1', key2: 'value2' }; // 替换为你要发送的数据

  this.http.post(url, data).subscribe(
    response => {
      console.log('请求成功', response);
      // 在这里处理响应数据
    },
    error => {
      console.error('请求失败', error);
      // 在这里处理错误
    }
  );
}
