angular2 canActivate()不适用于Observable响应

Question

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？

Answer 1

如果你通过其他方式添加.first()或完成Observable它应该工作:

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

要么

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