使用这个

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

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

主要是。ts进口

import 'rxjs/add/operator/filter';

EDIT

现代的方式

import {filter} from 'rxjs/operators';

router.events.pipe(
    filter(event => event instanceof NavigationEnd)
)
    .subscribe(event => {
        console.log(event);
    });

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

constructor(private router: Router) {
  // Detect current route
  router.events.subscribe(val => {
    if (val instanceof NavigationEnd) {
      console.log(val.url);
    }
  });
}

给那些还在寻找这个的人。在Angular 2上。有几种方法。

constructor(private router: Router, private activatedRoute: ActivatedRoute){

   // string path from root to current route. i.e /Root/CurrentRoute
   router.url 

    // just the fragment of the current route. i.e. CurrentRoute
   activatedRoute.url.value[0].path

    // same as above with urlSegment[]
   activatedRoute.url.subscribe((url: urlSegment[])=> console.log(url[0].path))

   // same as above
   activatedRoute.snapshot.url[0].path

   // the url fragment from the parent route i.e. Root
   // since the parent is an ActivatedRoute object, you can get the same using 
   activatedRoute.parent.url.value[0].path
}

在Angular2 Rc1中，你可以注入一个routessegment，然后将它传递给.navigate()方法:

constructor(private router:Router,private segment:RouteSegment) {}

ngOnInit() {
  this.router.navigate(["explore"],this.segment)
}

Angular 2 rc2

router.urlTree.contains(router.createUrlTree(['/home']))

对我来说，在AuthGuardService实现CanActivate访问当前路由时，接受的答案不工作，因为路由还没有完全处理。我在这里回答了同样的问题(https://stackoverflow.com/a/68541653/1479486)，但如果你只是想从这里复制粘贴，这是我的解决方案:

const finalUrl = this.router.getCurrentNavigation()?.finalUrl;   
const isLoginPage = finalUrl?.root.children['primary'].segments[0]?.path === 'login';
