class MyComponent {
  constructor(route: ActivatedRoute) {
    const url: string = route.snapshot.url.join('');
  }

应该可以的万一你只是想获取信息。

您可以订阅路由器事件以在导航到页面时获取url。

import { NavigationEnd, Router } from '@angular/router';

export class AppComponent {   

  constructor(router: Router) {
    
  const routerSubscription = this.router.events
   .pipe(
     filter(event => event instanceof NavigationEnd)
    )
   .subscribe((event: NavigationEnd) => {
      const url = event.url;
    
      if (url != '/') {

        // To stop listen navigations
        routerSubscription.unsubscribe();

        // Your code
      }

    });
  }
}
