Angularjs calling function at regular interval?

Question

The problem is simply to reload the authentication token at regular interval. I am using $interval service for that. the code is as follows

function refresh_session() {
    console.log("testing");
}

module.exports = function ($scope,$rootScope,$localStorage,$location,$interval,$http) {

    $interval(refresh_session,5000);

This works just fine, but i need to access variables inside $scope and $localStorage to update the token. I have tried both passing a function defined inside $scope to $interval service as well as passing parameters to external function. Both of them are not working. What is the correct way i can go about that using the angular method ?

Are you able to place the refresh_session function inside your exported function? That would allow it to access that functions arguments. Like this:

module.exports = function ($scope,$rootScope,$localStorage,$location,$interval,$http) {

    $interval(refresh_session,5000);

    function refresh_session() {
        console.log("testing", $scope, $localStorage);
    }
    ...
};

Alternatively, you can have a function that creates the refresh_session function:

function refreshSessionCreator($scope, $localStorage){
    return function(){
        console.log("testing", $scope, $localStorage);
    };
}

module.exports = function ($scope,$rootScope,$localStorage,$location,$interval,$http) {

    $interval(refreshSessionCreator($scope, $localStorage),5000);
    ...
};
