AngularJS - Intercept all ajax calls globally

Add following code in app module config section to handle success or error globally.

In below example i have handled 401 unauthorized error globally.

App.config(['$httpProvider', function ($httpProvider) {

    $httpProvider.defaults.useXDomain = true;

    $httpProvider.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded"; //Post

    delete $httpProvider.defaults.headers.common['X-Requested-With'];

    var interceptor = ['$rootScope', '$q', function (scope, $q) {

        function success(response) {

            return response;

        }

        function error(response) {

            var status = response.status;

            console.log("site error: " + status);

            if (status == 401) {

                window.location.href = currentDomain;

                return;

            }

            // otherwise

            return $q.reject(response);

        }

        return function (promise) {

            return promise.then(success, error);

        }

    }];

    $httpProvider.responseInterceptors.push(interceptor);

}]);
