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

这可能是你的答案，使用激活路由的params方法从你想要读取的URL/路由获取参数，下面是演示片段

import {ActivatedRoute} from '@angular/router'; 
@Component({
})
export class Test{
constructor(private route: ActivatedRoute){
this.route.params.subscribe(params => {
             this.yourVariable = params['required_param_name'];
        });
    }
}

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
            }); 

获取路由段:

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

constructor( route: ActivatedRoute) {}

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

import { Router } from '@angular/router';
constructor(router: Router) { 
      console.log(router.routerState.snapshot.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。
