controller getting called twice due to append params in url

Question

I am in angularjs. I am trying to append paramter in url using $location.search('sid', key);. The value of key is coming from another server by http request. Here is the code for append parameter.

.config(['$routeProvider',function ($routeProvider) {
        $routeProvider
            .when('/', {
                templateUrl: 'test1.html',
                controller: 'test1Controller'
            })
            .when('/message/:userId', {
                templateUrl: 'test2.html',
                controller: 'test2Controller'
            })
            .otherwise({
                redirectTo: '/'
            });
    }])
.run(['$route', '$rootScope', '$location' ,'getAuthDetails', function($route, $rootScope, $location,getAuthDetails) {
        var key;

        getAuthDetails.get().then(function(data){
            key = data.key;
            $rootScope.query = 'sid='+key;
            console.log($location.$$path);
            $location.search('sid', key);  //append parameter. This is calling controller twice
        });

        $rootScope.$on('$routeChangeSuccess', function () {
            $rootScope.query = 'sid='+key;
        });
    }]);

The problem i am having is . As the sid get append in url. The console.log i put in test1Controller getting called twice. Sid is used to connect with socket connection.

Is there any workaround to call the controller after the url append.

You can use reloadOnSearch: false

Example:

.config(['$routeProvider',function ($routeProvider) {
        $routeProvider
            .when('/', {
                templateUrl: 'test1.html',
                controller: 'test1Controller',
                reloadOnSearch: false // wont reload the controller when the search query changes
            })
            .when('/message/:userId', {
                templateUrl: 'test2.html',
                controller: 'test2Controller'
            })
            .otherwise({
                redirectTo: '/'
            });
    }])
