我的路由器带有canActivate: [ AuthGuard ]并在AuthGuard中进行了验证

如何在同一路由器URL中强制检查canActivate

例如:当前路线是/admin,我有类似session expired的事件。我在AuthGuard中进行了 session 检查,但是只有当我执行.navigate(...)时,此检查才会激活。如何强制在同一位置运行canActivate

我试过了:this.router.navigate([ this.router.url ]);,但是angular检查相同的位置并且什么也不做。

p.s.当我收到session expired event时,我可以定位到“登录页面”或其他页面,但是我在AuthGuard中拥有所有重定向,并且我不想在所有其他事件中重复相同的重定向,我需要像location.reload()一样,但是在Angular2 route 。

主要问题听起来像:如何强制在当前位置重新运行canActivate防护程序?

最佳答案

我的临时解决方案:

auth.service.ts

import { Injectable, Injector } from '@angular/core';
import { ActivatedRoute, Router, RouterStateSnapshot } from '@angular/router';

@Injectable()
export class AuthService {

  constructor(private route: ActivatedRoute,
              private router: Router,
              private injector: Injector) {
    this.forceRunAuthGuard();
  }

  // Dirty hack for angular2 routing recheck
  private forceRunAuthGuard() {
    if (this.route.root.children.length) {
      // gets current route
      const curr_route = this.route.root.children[ '0' ];
      // gets first guard class
      const AuthGuard = curr_route.snapshot.routeConfig.canActivate[ '0' ];
      // injects guard
      const authGuard = this.injector.get(AuthGuard);
      // makes custom RouterStateSnapshot object
      const routerStateSnapshot: RouterStateSnapshot = Object.assign({}, curr_route.snapshot, { url: this.router.url });
      // runs canActivate
      authGuard.canActivate(curr_route.snapshot, routerStateSnapshot);
    }
  }

}

app.routes.ts
  { path: 'faq', canActivate: [ AuthGuard ], component: FaqComponent },
  { path: 'about', canActivate: [ AuthGuard ], component: AboutUsComponent },
  { path: 'upgrade', canActivate: [ AuthGuard ], component: UpgradeComponent },

此代码再次运行AuthGuard
