內canActivate功能ActivatedRouteSnapshot和RouterStateSnapshot通過作爲參數傳遞：

@Injectable() 
export class HasPermissionService implements CanActivate { 

    private permissions = []; 

    constructor(private _core: CoreService) { 
    this.permissions = this._core.getPermission(); 
    } 

    canActivate(
     route: ActivatedRouteSnapshot, 
     state: RouterStateSnapshot 
    ): Observable<boolean>|Promise<boolean>|boolean { 
     //check here 
    } 
} 

你應該從那裏開始查看哪條路線正在啓動
