How to preserve my hash fragment in Angular 2 for openid token

I am using oauth for authentication in my Angular 2 application. After authentication I get all info in the return url after a hash. After routing inside my angular 2 program, the hash part is totally deleted, but I need it. This questions has been asked and answered before, but the answer did not solve my problem, my fragment is still "null". I think as mentioned in one of the answers. This solution is only for pathlocationstrategy, but I am using hashlocationstrategy

Retrieve hash fragment from url with Angular2

So, this is why the answer there does not solve my issue. Did anybody solve that issue while using "hashlocationstrategy"?

Solution

Thanks to a suggestion somewhere on the internet, but cannot find it anymore to give it credit, I used "window.location.hash". In the app.module.ts you have to put similar code:

constructor(public routerName: Router) {
console.log("Appmodule is starting")
routerName.events.subscribe(s => {
  if (s instanceof NavigationStart&&
           (s.toString().indexOf("/scope")>0) )
  { let tokenReceived=window.location.hash;
    this.decodeToken(tokenReceived);
  }
});

You are essentially to looking for a navigation to start and subscribe to it and as soon as your application is identifying /scope and navigating to it, the decoding of the received token starts. "decodeToken" is just my own method for decoding. This entails having a path for routing in your guard in the same file, namely:

{ path: 'scope', component: LoginComponent},

Hope this helps!
