AngularJS: Get previous url (path) from page - angularjs

Question

I have a question: When I'm in a page I want return to previous page. I use the $routeProvider. How can I read the previous url?
I try to use this code in my controller but doesn't work...
angular.module.controller('myController',
function($scope, $routeParams, $http, $location, $rootScope) {
$rootScope.$on("$routeChangeSuccess",
function (event, current, previous, rejection) {
console.log(previous);
$location.path('PREVIOUS PATH');
});
});
How can I read the previous path? Thanks!

I am not fully sure, what you want to achieve. So I would suggest, check this before you go your own way:
How to implement history.back() in angular.js
But, in case, you want to know how to keep the last state with angular and UI-Router, we can do it with a service. There is some naive implementation tracking just last state (not challenging the history.back())
Check the working example
Service definition:
.factory('PreviousState', ['$rootScope', '$state',
function ($rootScope, $state) {
var lastHref = "/home",
lastStateName = "home",
lastParams = {};
$rootScope.$on("$stateChangeSuccess", function (event, toState, toParams
, fromState, fromParams) {
lastStateName = fromState.name;
lastParams = fromParams;
lastHref = $state.href(lastStateName, lastParams)
})
return {
getLastHref: function (){ return lastHref ; },
goToLastState: function (){ return $state.go(lastStateName, lastParams); },
}
}])
So we just do listen the $stateChangeSuccess and keep the track of last state name and its $stateParams.
We can inject our service to all scopes:
.run(['$rootScope', 'PreviousState',
function ($rootScope, PreviousState) {
$rootScope.PreviousState = PreviousState;
}])
And we can use it as a click or href:
<button ng-click="PreviousState.goToLastState()">go back</button>
<a ng-href="#{{PreviousState.getLastHref()}}" > go to last href</a>
