要找到当前路由的父路由，你可以使用相对路由从路由器获取UrlTree:

var tree:UrlTree = router.createUrlTree(['../'], {relativeTo: route});

然后得到主出口的分段:

tree.root.children[PRIMARY_OUTLET].segments;

这个是在Angular 11上测试的

constructor(private router: Router) {
  this.router.events
   .pipe(filter((event: any) => event instanceof NavigationEnd))
   .subscribe((event: any) => {
     this.currentRoute = event.url;
     console.log(event);
   });
 }

新建路由器>= RC.3

最好和一个简单的方法来做到这一点是!

import { Router } from '@angular/router';
constructor(router: Router) { 
      router.events.subscribe((url:any) => console.log(url));
      console.log(router.url);  // to print only path eg:"/login"
}

this.router.events.subscribe((val) => {
   const currentPage = this.router.url; // Current page route
  const currentLocation = (this.platformLocation as any).location.href; // Current page url
});

获取路由段:

import { ActivatedRoute, UrlSegment } from '@angular/router';

constructor( route: ActivatedRoute) {}

getRoutes() { const segments: UrlSegment[] = this.route.snapshot.url; }

这适用于与authguard一起使用的情况

this.router.events.subscribe(event => {
        if(event instanceof NavigationStart){
            console.log('this is what your looking for ', event.url);  
         }
       } 
   );
