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。

将Location注入组件并读取Location .path(); 你需要在某个地方添加ROUTER_DIRECTIVES，这样Angular才能解析Location。你需要在这个模块中添加import: [RouterModule]。

更新

在V3 (RC.3)路由器中，您可以注入ActivatedRoute，并使用它的snapshot属性访问更多细节。

constructor(private route:ActivatedRoute) {
  console.log(route);
}

or

constructor(private router:Router) {
  router.events.subscribe(...);
}

另见Angular 2的路由器事件侦听器

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)
}

本机窗口对象也可以正常工作

console.log('URL:' + window.location.href);
console.log('Path:' + window.location.pathname);
console.log('Host:' + window.location.host);
console.log('Hostname:' + window.location.hostname);
console.log('Origin:' + window.location.origin);
console.log('Port:' + window.location.port);
console.log('Search String:' + window.location.search);

注意:不要在服务器端渲染中使用这个

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

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);
   });
 }
