Angular router url returns slash

问题

I'm trying to get the current router path by using Router, but when i do console.log(this.router.url) it returns "/", although i'm on the "/login". But when i'm consoling the entire this.router object, there is the property url which has value "/login".

here is my code from app.component.ts

export class AppComponent implements OnInit{
  constructor(private router: Router) {}

  ngOnInit(){
    console.log(this.router);
  }

}

app.module.routing.ts

import {NgModule} from '@angular/core';
import {PreloadAllModules, RouterModule, Routes} from '@angular/router';

import {NotFoundComponent} from './not-found/not-found.component';
import {AuthGuard} from './auth/auth-guard.service';

const appRoutes: Routes = [
  { path: '', loadChildren: './first/first.module#FirstModule'},
  { path: 'login', loadChildren: './login/login.module#LoginModule'},
  { path: '404', component: NotFoundComponent, canActivate: [AuthGuard] },
  { path: '**', redirectTo: '/404'}
];

@NgModule({
  imports: [RouterModule.forRoot(appRoutes, {preloadingStrategy: PreloadAllModules})],
  exports: [RouterModule]
})
export class AppModuleRouting {}

and the FirstModule routing:

import {NgModule} from '@angular/core';
import {RouterModule, Routes} from '@angular/router';

import {FirstComponent} from './first.component';
import {AuthGuard} from '../auth/auth-guard.service';

const firstRoutes: Routes = [
  { path: '', component: FirstComponent, canActivate: [AuthGuard], children:[
    { path: '', loadChildren: './content-container/container.module#ContainerModule' }
  ]}
];
@NgModule({
  imports: [RouterModule.forChild(firstRoutes)],
  exports: [RouterModule]
})
export class FirstRoutes {}

Instead of trying to use Router (which is not ready to give you final route at this moment of navigation lifecycle), you can use Location service (https://angular.io/api/common/Location) and its method path, which will give you the url without base href. On the contrary, window.location.pathname is not aware of your angular toys and will give you path including base href.

import { Location } from '@angular/common';

export class AppComponent implements OnInit {
  constructor(private location: Location) {}

  ngOnInit(){
    console.log(this.location.path());
  }

}

I have the same issue. The router.url returns a slash because when ngOnInit runs on the main app component, the route is the root. I got the correct value for the url by doing this.

  this.router.events
  .pipe(
    filter(e => e instanceof NavigationEnd)
  )
  .subscribe( (navEnd:NavigationEnd) => {
    console.log(navEnd.urlAfterRedirects);
  });

Hope that helps. This did not work with Angular Universal however... still trying to figure that out.

Type 1.We can also use window.location.pathname

Type 2.constructor(router: Router) { 

      router.events.subscribe((url:any) => console.log(url));

      console.log(router.url);  // to print only path eg:"/login"
}
