我有canActivate angular2.0.0-rc.3的问题.

canActivate(next: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean>{
    console.log('canActivate with AclService'); 
   // return true;
    return Observable.create((observer:Subject<boolean>) => { observer.next(true);  });
   }

它不适用于Observable响应,但使用简单的布尔响应.

我怎么能解决这个问题？

在使用路由器模块v 3.0.0.6alpha的angular2 rc2中,我扩展了RouterOulet以检查用户是否在访问管理员之前已登录.所以这是代码:

@Directive({
    selector: 'router-outlet'
})

export class LoggedInRouterOutlet extends RouterOutlet 
{
    publicRoutes: Array<string>;
    private parentOutletMap: RouterOutletMap;
    private userService: UserService;
    private parentRouter: Router;

    constructor(
        parentOutletMap: RouterOutletMap,
        _location: ViewContainerRef,
        @Attribute('name') name: string,
        userService: UserService,
        parentRouter: Router
    ) { 
        super(parentOutletMap, _location, name);

        this.parentRouter = parentRouter;
        this.parentOutletMap = parentOutletMap;
        this.userService = userService;
        this.publicRoutes = [
            'public', 
            'login'
        ];
    }

    activate(factory: ComponentFactory<any>, activatedRoute: ActivatedRoute, providers: ResolvedReflectiveProvider[], outletMap: RouterOutletMap) 
    {
        if (this._canActivate(factory.selector)) { 
            return super.activate(factory, activatedRoute, providers, outletMap); 
        }

        this.parentRouter.navigate(['/login']);
    }

    _canActivate(url) {
        return …
