角4。X及以上:

这可以通过使用ActivatedRoute类的url属性来实现，如下所示:

this.activatedRoute.url.subscribe(url =>{
     console.log(url);
});

注意: 你需要从angular/router包中导入和注入提供商

import { ActivatedRoute } from '@angular/router`

and

constructor(private activatedRoute : ActivatedRoute){  }

为那些使用Angular9+的人更新了答案，通过使用@angular/ Router提供的路由器API并监听路由变化

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

    @Component({
      selector: 'my-app',
      templateUrl: './app.component.html',
      styleUrls: [ './app.component.css' ]
    })
    export class AppComponent  {
      
      name = 'Get Current Url Route Demo';
      currentRoute: string;
     routeSubscription: subscription;
    
      constructor(private router: Router){
        console.log(router.url);
        
        this.routeSubscription = router.events.filter(event => event instanceof NavigationEnd)
              .subscribe(event => 
               {
                  this.currentRoute = event.url;          
                  console.log(event);
               });
        }
    }

在组件中，你可能想尝试这样做:

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

constructor(private router: Router) {
router.events.subscribe(
        (event) => {
            if (event instanceof NavigationStart)
                // start loading pages
            if (event instanceof NavigationEnd) {
                // end of loading paegs
            }
        });
}

只需在AppRoutingModule上进行更改

@NgModule({
imports: [RouterModule.forRoot(routes, { scrollPositionRestoration: 'enabled' })],
  exports: [RouterModule]
})

在花了一些时间寻找解决方案后，我找到了Angular 13.1.1的两个更新的变通方案:

第一选择:

  constructor(private router: Router) {
    router.events.forEach((event) => {
      if (event instanceof NavigationStart) {
        // Your code
        // Use (event.url) to get URL that is being navigated
      }
    });
  }

第二个选项

routerSubscription:订阅| undefined; 构造函数(私有路由器:router) {} ngAfterViewInit(): void { 这一点。routerSubscription = this.router.events.subscribe((event) => { if(事件实例of NavigationEnd) { //你的代码 //使用(event.url)获取正在导航的URL ｝ })； ｝

记得取消订阅销毁循环

 ngOnDestroy(): void {
    this.routerSubscription?.unsubscribe();
  }

还要根据您的情况注意是否更好地使用

事件实例的NavigationStart

or

事件实例的NavigationEnd

Angular 7，如果你想订阅路由器

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

import { filter } from 'rxjs/operators';

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