如何从angular向Google Analytics报告当前标题？

<script async src="https://www.googletagmanager.com/gtag/js?id=GA_TRACKING_ID"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'GA_TRACKING_ID');
</script>

ng generate service google-analytics

import { Injectable } from '@angular/core';
declare var gtag: Function;

@Injectable({
  providedIn: 'root'
})
export class GoogleAnalyticsService {

  constructor() { }

  public sendPageView(url: string, title: string): void {
    gtag('config', 'GA_TRACKING_ID', {
      'page_path': url,
      'page_title': title
    });
  }
}

import { GoogleAnalyticsService } from 'path/to/google-analytics.service';

@Component({
  selector: 'app-example',
  templateUrl: './example.component.html',
  styleUrls: ['./example.component.css']
})
export class ExampleComponent implements OnInit {

  constructor(private googleAnalyticsService: GoogleAnalyticsService) { }

  ngOnInit(): void {
    this.reportPageView();
  }

  private reportPageView(): void {
    const currentUrl = window.location.pathname;
    const currentTitle = '当前标题'; // 替换为您想要报告的实际标题
    this.googleAnalyticsService.sendPageView(currentUrl, currentTitle);
  }

}
