如何在angular2中通过本地将数据发布到生产网站？

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

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

  publishData(data: any) {
    return this.http.post('http://example.com/api/data', data);
  }
}

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

@Component({
  selector: 'app-root',
  template: `
    <form (submit)="publishData()">
      <input type="text" [(ngModel)]="data" name="data" placeholder="Enter data">
      <button type="submit">Publish</button>
    </form>
  `,
})
export class AppComponent {
  data: string;

  constructor(private dataService: DataService) { }

  publishData() {
    this.dataService.publishData(this.data)
      .subscribe(response => {
        console.log('Data published successfully');
      }, error => {
        console.error('Failed to publish data');
      });
  }
}
