javascript - Angular2 routing canActivate and AuthGuard (JWT) with user role parameter -

-

in exaple project jwt authentication se how allow authenticated users route:

import { routerconfig } '@angular/router'; import { home } './home'; import { login } './login'; import { signup } './signup'; import { authguard } './common/auth.guard';  export const routes: routerconfig = [   { path: '',       component:  login },   { path: 'login',  component: login },   { path: 'signup', component: signup },   { path: 'home',   component: home, canactivate: [authguard] },   { path: '**',     component: login }, ];

i make step further , indicate user role have 'access' route - don't know how pass argument canactivate authguard (src). achieve (for instance have 2 roles: admin , employee):

  { path: 'home',   component: home, canactivate: [authguard] },   { path: 'users',   component: adminusers, canactivate: [authguard('admin')] },   { path: 'users',   component: employees, canactivate: [authguard('employee')] },

where authguard (where userrole(= admin or employee or null) passed parameter authguard):

@injectable() export class authguard implements canactivate {   constructor(private router: router) {}    canactivate(userrole) {     if (!userrole || jwt.user().role == userrole) {       return true;     }      this.router.navigate(['/login']);     return false;   } }

where jwt.user.role helper read user role stored in jwt token. there way similar above idea?

the signature canactivate won't allow pass userrole want to. https://github.com/angular/angular/blob/2.0.0-rc.4/modules/%40angular/router/src/interfaces.ts#l54

it's best separate classes each of user role cases. that's guidance in official docs too: https://angular.io/docs/ts/latest/api/router/index/canactivate-interface.html
