如何使用我的节点端点从angular元件插入数据？

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

@Injectable({
  providedIn: 'root'
})
export class DataService {
  constructor(private http: HttpClient) {}

  insertData(data: any): Observable<any> {
    return this.http.post<any>('http://your-node-endpoint', data);
  }
}

import { Component } from '@angular/core';
import { DataService } from './data.service';

@Component({
  selector: 'app-my-component',
  template: `
    <button (click)="insertData()">Insert Data</button>
  `
})
export class MyComponent {
  constructor(private dataService: DataService) {}

  insertData() {
    const data = { name: 'John', age: 25 };
    this.dataService.insertData(data).subscribe(
      response => {
        console.log('Data inserted successfully');
      },
      error => {
        console.error('Error inserting data:', error);
      }
    );
  }
}
