角2认证与子路由 [英] Angular 2 Authentication with child routes

问题描述

我有一个角2应用程序中，我需要在每一页上进行身份验证。所以，我实现了自定义RouterOutlet确认我登录在每一页的变化。

I have an angular 2 application in which I need to be authenticated on every page. So I have implemented a custom RouterOutlet to confirm I am logged in on every page change.

@Directive({
   selector: 'auth-outlet'
})
export class AuthOutlet extends RouterOutlet {
   publicRoutes: any;
   private parentRouter: Router;
   private authService: AuthService;
   constructor(_elementRef: ElementRef, 
               _loader: DynamicComponentLoader, 
               _parentRouter: Router,
               @Attribute('name') nameAttr: string, 
               _authService: AuthService) {

      super(_elementRef, _loader, _parentRouter, nameAttr);
      this.parentRouter = _parentRouter;
      this.authService = _authService;
      this.publicRoutes = {
          'Login': true
      };
  }

  activate(oldInstruction: ComponentInstruction) {
      var url = this.parentRouter.lastNavigationAttempt;
      console.log('attemping to nav');
      if (!this.publicRoutes[url] && !this.authService.loggedIn){
          var newInstruction = new ComponentInstruction('Login', [], new RouteData(), Login, false, 1);
          return super.activate(newInstruction);
      } else {
          return super.activate(oldInstruction);
      }
   }
}

下面是一个工作code：

Here is a working code: http://plnkr.co/edit/YnQv7Mh9Lxc0l0dgAo7B?p=preview

有没有更好的办法拦截路线的变化和重定向登录时，用户没有通过验证？

Is there a better way to intercept route changes and redirect for login when the user is not authenticated?

推荐答案

您也可以使用的 CanActivate ，但是直销DI是不是此刻的支持。这里是一个不错的解决方法寿。

祝你好运。
