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
}

在组件文件中:

import {ActivatedRouteSnapshot} from '@angular/router';

constructor(state: ActivatedRouteSnapshot) {
    console.log(state.path)
}

在路由文件中:

这很简单，在angular 2中，你只需要像这样导入Router库:

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

然后在组件或服务的构造函数中，你必须像这样实例化它:

constructor(private _router: Router) {}

然后在代码的任何部分，函数、方法、构造等等:

      this._router.events
        .subscribe(
            (url:any) => {
                let _ruta = "";
                url.url.split("/").forEach(element => {
                    if(element!=="" && _ruta==="")
                        _ruta="/"+element;  
                });
                console.log("route: "+_ruta); //<<<---- Root path
                console.log("to URL:"+url.url); //<<<---- Destination URL                    
                console.log("from URL:"+this._router.url);//<<<---- Current URL
            });

router.events。订阅(e => { if (e instanceof NavigationEnd) { 这一点。currentUrl = e.url; ｝ })；

你可以试试

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

constructor(private router: Router, private activatedRoute:ActivatedRoute) {
console.log(activatedRoute.snapshot.url)  // array of states
console.log(activatedRoute.snapshot.url[0].path) }

替代的方法

router.location.path();   this works only in browser console. 

window。location。pathname给出了路径名。
