Angular 2 get current route in guard

Question

I have an AccessGuard class in my project which its work is to determine if user can access to the route or not. I used the router.url to get the current route

this could help you:

1. Import ActivatedRouteSnapshot and RouterStateSnapshot:

   import { Router, CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot} from '@angular/router';

2. Signature in the canActivate:

   canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot):Observable {}

3. Check the state:

   console.log("route-access",state);

Your Guard file would look something like this:

    import { Injectable } from '@angular/core';
    import { Router, CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot} from '@angular/router';
    import { Observable } from 'rxjs';
    import { AutenticacionService } from 'app/services/index';
    @Injectable()
    export class AuthGuard implements CanActivate {
        constructor(private _router: Router, private auth:AutenticacionService) {}
    canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot):Observable {
        // console.log("route-access",state);
        let _url:string="";
        state.url.split("/").forEach(element => {
            if(_url==="")
                if(element!=="")
                    _url=element;
        });
        // console.log(_url);
        return this.auth.check(_url)
          .map((result) => {
                    if (result) {
                        return true;
                    } else {
                        this._router.navigate(['/']);
                        return false;
                    }
                });  
    }

}
