angularjs - Angular2 Component Router : Capture query parameters -

i'm struggling capture url query string parameters being passed angular2 app 3rd party api. url reads http://example.com?oauth_token=123

how can capture value of "oauth_token" inside component? i'm happily using component router basic routing it's query string. have made several attempts , latest receiving component looks like

import { component, oninit } '@angular/core'; import { activatedroute } '@angular/router';  @component({     template: '' }) export class twitterauthorisedcomponent implements oninit {      private oauth_token:string;      constructor(private route: activatedroute) {}      ngoninit() {         console.log('the oauth token is');         console.log( this.route.snapshot.params.oauth_token );     } }  

any advice appreciated.

** update

if comment out routes query parameters stick however, moment include route query parameters removed on page load. below stripped down copy of routes file 1 route

import {navigationcomponent} "./navigation/components/navigation.component"; import {twitterauthorisedcomponent} "./twitter/components/twitter-authorised.component";  import { providerouter, routerconfig } '@angular/router';  export const routes: routerconfig = [     { path: '', component: twitterauthorisedcomponent } ];  export const approuterproviders = [     providerouter(routes) ]; 

if remove route query params stick. advice?

i can catch query prams using bellow solution.

import { router, route, activatedroute } '@angular/router';  queryparams:string;  constructor(private router: router, private actroute: activatedroute)  {     this.queryparams=     this.router.routerstate.snapshot.root.queryparams["oauth_token"]; } 

using value of oauth_token queryparams. think seems fine you

if need update value queryparams, query parameter changes need add more code. below.

    import { router, route, activatedroute } '@angular/router';      queryparams:string;     sub:any;      constructor(private router: router, private actroute: activatedroute)      {         this.queryparams=         this.router.routerstate.snapshot.root.queryparams["oauth_token"];     }     ngoninit(){     this.sub = this.router.routerstate.root.queryparams.subscribe(params => {       this.queryparams = params["oauth_token"];     });     } 

hope work you.
