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);
    }
  });
}

如果你不能访问路由器，这是一个更简单的方法。url(例如，如果你使用skipLocationChange)，你可以使用以下:

import { Location } from '@angular/common';    
constructor(private readonly location: Location) {}
    
ngOnInit(): void {
  console.log(this.location.path());
}

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);
    }
  });
}

在组件文件中:

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

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

在路由文件中:

Angular 2 rc2

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

简单的方法

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