How to authenticate using AngularJS

auth.js

services.factory('Auth', function($http){
  return {
	    load: function() {
			return $http.get('/api/v1/auth');
		},
	    logout: function() {
			return $http.get('/api/v1/auth/logout');
		},
		login: function(inputs) {
			return $http.post('/api/v1/auth/login', inputs);
		},
		register: function(inputs) {
			return $http.post('/api/v1/auth/register', inputs);
		},
		locations: function() {
			return $http.get('/api/v1/auth/locations');
		},
		check: function() {
			return $http.get('/api/v1/auth/check');
		}
	}
});

MainCtrl.js

controllers.controller('MainCtrl', function($scope, $location, Facebook, $rootScope, $http, $location, Upload, Auth, User, Question, Category, Serie, Record, Location, Popup, Process, Card, Question) {
  $scope.$on('authLoaded', function() {
		$scope.isExpert($scope.main.serieId);
		$scope.isMember($scope.main.serieId);
	});

	$scope.loadAuth = function() {
		Auth.load().success(function(data) {
			$scope.main.user = data.user;
			$scope.$broadcast("authLoaded");
			Popup.close();
		});
	}
  
  
	$scope.logoutUser = function() {
		Auth.logout().success(function(data) {
			toastr.info("You have been logged out.");
			$scope.main.user = {};
		});
	}

	$scope.loginUser = function() {
		Auth.login({
			username: $scope.main.credentials.email,
			password: $scope.main.credentials.password
		}).success(function(data) {
			if (data.error) {
				toastr.error(data.error);
			} else {
				toastr.success("You are signed in!");
				$scope.loadAuth();
				$scope.main.credentials = {};
				Popup.close();
			}
		});
	}

	$scope.registerUser = function() {
		Auth.register({
			serie_id: $scope.main.serieId,
			email: $scope.newUser.email,
			password: $scope.newUser.password,
			terms: $scope.newUser.terms,
			name: $scope.newUser.name,
		}).success(function(data) {
			if (data.error) {
				toastr.error(data.error);
			}

			if (data.success) {
				toastr.success("Welcome to " + $scope.main.serie.name + "!");
				$scope.loadAuth();
				$scope.newUser = {};
				Popup.close();
			}
		});
	}
 	
 	$scope.loadAuth();
	$scope.loadSerie();
});

is the MainCtrl , the controller attached to body tag ?

@Sshuichi probably it's attached to the view, in the routing itself.

When the http request is being made, Is it calling directly the methods inside the auth.php file or are those separate files?
