javascript - Angular2: how to "reload" page with router (recheck canActivate)? -


i have routers canactivate: [ authguard ] , validation inside authguard

how force check canactivate in same router url ?

for example: current route /admin , have got event session expired. have session check in authguard check activates when execute .navigate(...). how force run canactivate in same location?

i've tried: this.router.navigate([ this.router.url ]); angular checks same location , nothing.

p.s. can locate "login page" or other pages when got session expired event, have redirects inside authguard , not want repeat same redirects in other events, need location.reload() in angular2 routes.

main question sounds like: how force rerun canactivate guards in current location?

my temporary solution:

auth.service.ts

import { injectable, injector } '@angular/core'; import { activatedroute, router, routerstatesnapshot } '@angular/router';  @injectable() export class authservice {    constructor(private route: activatedroute,               private router: router,               private injector: injector) {     this.forcerunauthguard();   }    // dirty hack 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 },

this code runs authguard again.
