Inject Router using Injector.resolveAndCreate inside a class

Question

Is it possible to inject Router using Injector.resolveAndCreate() ?

import {ExceptionHandler, Injectable, Inject,Injector} from 'angular2/core';
import {Router,ROUTER_PRIMARY_COMPONENT} from 'angular2/router';

@Injectable()
export class MyExceptionHandler implements ExceptionHandler{

    constructor(public router: Router) { }
    call(error, stackTrace = null, reason = null) {
        console.log("ERROR >> " + error);
        console.log("STACKTRACE >> " + stackTrace);
        console.log("REASON >> " + reason);
        let injector: any = Injector.resolveAndCreate([Router]);
        let router: Router = injector.get(Router);
        router.navigateByUrl('/error');       
        
    }
}

Getting EXCEPTION: Error during instantiation of Token RouterPrimaryComponent! (e -> Router -> RouteRegistry -> Token RouterPrimaryComponent).

Have you tried it? (the answer as you would have discovered would be yes) — SnareChops, Feb 03 '16 at 04:14

Sure, if you use an injector that has ROUTER_PROVIDERS registered, but you usually don't want a Router instance but the Router instance - the one used in the application. For this you need to use the same Injector as the Angular application uses.

This might be what you are looking for Redirect to a different component inside @CanActivate in Angular2

Thanks @Gunter. I have updated the code and the error i am getting .Can you please take a look . – Vinz and Tonz Feb 03 '16 at 12:31
I don't think what your updated code shows is what you actually want. You'd get a different `Router` instance than the one used by Angular. Don't you get the `Router` instance passed already to your `constructor(...)`? – Günter Zöchbauer Feb 03 '16 at 12:35
The router passed in the constructor is null – Vinz and Tonz Feb 14 '16 at 01:25
Can you please add the code that demonstrates what you have tried to your question? – Günter Zöchbauer Feb 14 '16 at 07:37
