Angular 2/4 How to get route parameters in app component?

enter image description hereAs I am new to angular 2/4 I am having trouble setting up a new application as per my need.

I am trying to build an application which will be called for from some another application. Calling application will send some parameter like token, username, application id and etc.

Now, as in Angular 2/4, app.component is our landing component and every first request will go through it. So, I want to get those parameter here in app component and load some user detail, make a local session and the move to other stuff.

problem is when I am trying to access these parameter I am getting anything.

Here is the URL which will start my angular application: http://localhost:86/dashboard?username=admin&token=xyz&appId=8

Here is my routing file code:

const routes: Routes = [
  {
    path: 'dashboard/:username, token', component: AppComponent
  }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule {

}

Here is my App Component Code:

import { Component, OnInit } from '@angular/core';
import { AuthenticationService } from 'app/services/authentication/authentication.service';
import { User } from 'app/models/user/user';
import { AppConfig } from 'app/helpers/AppConfig';
import { ActivatedRoute, Router } from '@angular/router';


@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  _user: User = new User();
  obj: any;
  error: any;

  loginName: string;
  private id: any;

  constructor(
    private authenticationService: AuthenticationService,
    private config: AppConfig,
    private route: ActivatedRoute,
    private router: Router

  ) { }

  ngOnInit() {    
    this.loadCurrentUserDetail();
    this.getParamValues()

  }

  getParamValues() {
    this.id = this.route.queryParams.subscribe(params => {      
       this.loginName = params['username']; 
    });
  }

Here params is empty don't know why?

Thanks in advance!

As in image params object has nothing.
