如何使用$ http创建动态服务和工厂角度并使用控制器发布

var drc = angular.module('DirectiveControllers',[]);

drc.controller('HeaderDrcCtrl', ['$scope','$http', function ($scope,$http) {
  if($.cookie('userEmail') != '') {
    $('#logout').show();
    $('#login').hide();
  }   

  $(document).on('click','#editForm', function() {
    $('#showEdit').show();
    $('#hideRegister').hide();
  });

  $scope.user = {};
  $scope.customers = {};
  $scope.signUp = function () {
    $http.post('/api/customers', {firstname: $scope.user.firstname, lastname: $scope.user.lastname, username:$scope.user.username, email:$scope.user.email, password: $scope.user.password})
      .success(function(data){
        $scope.customers.push({firstname: $scope.user.firstname, lastname: $scope.user.lastname, username:$scope.user.username, email:$scope.user.email, password: $scope.user.password});
        $scope.regMessage = data.Message;
        $scope.user = {};
      })
      .error(function(data){
          console.log('Error: ' + data);
      });
    }
  }]);
var drc = angular.module('DirectiveControllers'
