Angular state : pass multiple parameter without changing url querystring to controller - angularjs

Question

I want to send a parameter from app.run to my loginController. Because, I call a state.go() from the $rootScope.$on() defined inside the app.run.
app.run('$rootScope', '$state', '$stateParams',function($rootScope, $state, $stateParams(){
$rootScope.$state = $state;
$rootScope.$stateParams = $stateParams;
$rootScope.$on('unauthorized_access', function (event, args) {
$state.go("page.login", {'error': args.error,'msg': args.msg});
});
}]);
I have
app.config(['$stateProvider','$urlRouterProvider',function($stateProvider, $urlRouterProvider, $httpProvider){
$urlRouterProvider.otherwise('/');
$stateProvider
// some parts omitted...
.state('page.login', {
url: '/login',
views: {
'page': {
templateUrl: 'app/landingPage/login.html',
controller: 'loginController',
params: {obj : {error : null, message: null} }
}
}
});
}]);
and I want to pass parameters to the loginController from app.run, through $state.go() during transition.
$state.go("page.login", {'error': err,'message': msg});
and in my controller, this is how I am trying to receive the params...
app.controller('loginController',['$scope', '$state', '$stateParams', function($scope, $state, $stateParams){
console.log($stateParams.obj);
}]);
I do not want to change the url to >> url: '/login/:params' etc. in stateProvider
I referenced this page : stackoverflow example
but,was not helpful. Any help is appreciated. Apologies for my poor communication.

After a long research, I ended up with weird solution. I still doubt, whether this is even a solution. However, it does work for me.... I made a hack of ui.router LOL ....
I am using Angular ui-router version v0.2.18. and there at line no. 3160, they have put a line of code like :
// Store the hash param for later (since it will be stripped out by various methods)
var hash = toParams['#'];
and in line no. 3223 they have
if (shouldSkipReload(to, toParams, from, fromParams, locals, options)) {
if (hash) toParams['#'] = hash;
So, I thought of passing my object with a '#' key like this
.state('page.login', {
url: '/login',
views: {
'body#page': {
templateUrl: 'app/landingPage/login.html',
controller: 'loginController',
params: {'#' : null},
}
},
authenticate: false
});
and like this
$rootScope.$on('unauthorized_access', function (event, args) {
$state.go("page.login", {'#' : {'error': args.error,'msg': args.msg}});
});
and surprise, it worked.....
I got the object logged in console : console.log($stateParams['#']);
I know the solution is cunning[udayip as in malayalam]... but then it worked for me... I will not mark this as an answer. So, I request some angular experts to provide a real solution. If some experts say, this can be a solution, I will mark this as the answer.
