我有一个自定义异常处理程序,如果发生任何异常(只是尝试它),它应该将用户带到自定义错误页面.

我试图使用Injector获取路由器的实例.这样做的原因,我相信注入器将给现有的路由器实例并使用它我将能够路由用户.

任何想法为什么这不起作用或如何实现这一点？

谢谢 :)

@Injectable()
export class AppExceptionHandler extends ExceptionHandler{

constructor(){
    super(null, null);
}

call(exception:any, stackTrace?:any, reason?:string):void {
    console.log('call...')


    var providers = Injector.resolve([ROUTER_PROVIDERS]);
    var injector = Injector.fromResolvedProviders(providers);

    // this is causing issue, not sure it is the correct way
    let router : Router = injector.get(Router);

    // not executed
    console.log(router)

    // not executed 
    console.log('done...')
    router.navigate(["CustomErrorPage"]);
    }

}
