我有一个简单的应用程序，它通过Appcomponent加载材质设计Ui。我需要在加载应用程序组件之前对用户进行身份验证

应用程序组件如下所示

import {Component} from 'angular2/core';
import {Router, RouteConfig, ROUTER_DIRECTIVES,CanActivate} from 'angular2/router';
import {AuthHttp,AuthConfig, tokenNotExpired, AUTH_PROVIDERS} from 'angular2-jwt';


import {HomeComponent} from '../home/HomeComponent'
import {AboutComponent} from '../about/AboutComponent'
import {HeaderComponent} from './HeaderComponent'
import {LoginComponent} from '../login/LoginComponent'
import {AuthService} from '../../services/AuthService'
import {SidebarComponent} from './SidebarComponent'
import {DashboardComponent} from './DashboardComponent'
import {MDL} from './MaterialDesignLiteUpgradeElement';


@RouteConfig([
    {path: 'app/home', component: HomeComponent, as: 'Home'},
    {path: 'app/dashboard', component: DashboardComponent, as: 'Dashboard'},
    {path: 'app/about', component: AboutComponent, as: 'About'},    
    {path: 'app/login', component: LoginComponent, as: 'Login'},
    {path: 'app/*', redirectTo: ['Login']}   // this redirect is not working for some reason
])
@Component({
    selector: 'my-app',
    /*template: '<router-outlet></router-outlet>',*/
   template: `
    <body>
    <div class="demo-layout mdl-layout mdl-js-layout mdl-layout--fixed-drawer mdl-layout--fixed-header">
      <app-header mdl class="demo-header mdl-layout__header mdl-color--grey-100 mdl-color-text--grey-600"></app-    header>
      <app-sidebar class="demo-drawer mdl-layout__drawer mdl-color--blue-grey-900 mdl-color-text--blue-grey-50">
      </app-sidebar>
      <main class="mdl-layout__content mdl-color--grey-100">

          <router-outlet></router-outlet>

      </main>
    </div>

    <script src="https://code.getmdl.io/1.1.3/material.min.js"></script>
  </body>

    `, 
    /*styleUrls: ['../app/assets/styles.css'], */
    directives: [ROUTER_DIRECTIVES,SidebarComponent,HeaderComponent,MDL],
    providers: [AUTH_PROVIDERS,AuthService]
})

export class AppComponent { 

  constructor() {}

}
登录组件使用AuthService

import {Injectable} from 'angular2/core';
import {ROUTER_DIRECTIVES, Router} from "angular2/router";

declare var Auth0Lock: any;

@Injectable()
export class AuthService {

constructor(private router: Router) {}


  lock = new Auth0Lock('KEY','URL');

  login() {
   this.lock.show((error: string, profile: Object, id_token: string) => {
     if (error) {
       console.log(error);
       return false;
     }

     localStorage.setItem('profile', JSON.stringify(profile));
     localStorage.setItem('id_token', id_token);
     this.router.navigate(['Home']);

    });
 }

 logout() {
   localStorage.removeItem('profile');
   localStorage.removeItem('id_token');
 }
}
授权服务

import {Injectable} from 'angular2/core';
import {ROUTER_DIRECTIVES, Router} from "angular2/router";

declare var Auth0Lock: any;

@Injectable()
export class AuthService {

constructor(private router: Router) {}


  lock = new Auth0Lock('KEY','URL');

  login() {
   this.lock.show((error: string, profile: Object, id_token: string) => {
     if (error) {
       console.log(error);
       return false;
     }

     localStorage.setItem('profile', JSON.stringify(profile));
     localStorage.setItem('id_token', id_token);
     this.router.navigate(['Home']);

    });
 }

 logout() {
   localStorage.removeItem('profile');
   localStorage.removeItem('id_token');
 }
}
我试着用@CanActivate注释AppComponent，如下所示 但这似乎不起作用，因为AppComponent是以任何方式加载的

@CanActivate(() => LoginComponent.loggedIn())
export class AppComponent {      
}
有没有办法防止appComponent在没有授权的情况下加载

您可以实现自己的
RouterOutlet
，如果允许此人导航到该路线，该方法将覆盖要检查的
acitvate
方法

import {Directive, DynamicComponentLoader, ElementRef} from "angular2/core";
import {AuthService} from '../../services/AuthService'
import {Router, RouterOutlet, ComponentInstruction} from "angular2/router";

@Directive({
    selector: 'auth-router-outlet'
})
export class AuthRouterOutlet extends RouterOutlet {
    private _protectedRoutes = {
        'app/home': true,
        'app/dashboard': true,
        'app/about': true
    };

    constructor(_elementRef: ElementRef, _loader: DynamicComponentLoader, private _router: Router, nameAttr: string, private _authService: AuthService) {
        super(_elementRef, _loader, _router, nameAttr);
    }

    activate(nextInstruction: ComponentInstruction): Promise<any> {
        if (this._protectedRoutes[nextInstruction.urlPath]) {
            if (!this._authService.loggedIn()) {
                this._router.navigate(['Login']);
            }
        }

        return super.activate(nextInstruction);
    }
}
类型“ComponentInstruction”上不存在属性“routeName”。。loggedIn（）方法中还有什么？令牌？您确切使用的是哪个版本的Angular？版本是2.0.0-beta。17
loggedIn（）
我猜返回令牌的状态？我使用的是完全相同的版本，自定义路由器插座没有问题。你们有进口货吗？谢谢。似乎正在工作，但我的基本url仍然没有受到保护。我添加了这个导出类AuthRouterOutlet扩展了RouterOutlet{private _protectedRoutes={'app/'：true，'app/home'：true，'app/dashboard'：true，'app/about'：true}； 
@RouteConfig([
    {path: 'app/home', component: HomeComponent, as: 'Home'},
    {path: 'app/dashboard', component: DashboardComponent, as: 'Dashboard'},
    {path: 'app/about', component: AboutComponent, as: 'About'},    
    {path: 'app/login', component: LoginComponent, as: 'Login'},
    {path: 'app/**', redirectTo: ['Login']}   // two asterisks here
])
