You have to define the $http variable in your controller.

app.controller('TestController', function TestController($scope, $http) {
}

something like this. In the run method try something like this.

angular.module('yourApp').run(['$rootScope', '$http', function ($rootScope, $http) {
  // do stuff here
}]);
