Promise returning object in angular js - angularjs

Question

i have my authservice as given below ,
myApp.factory('Authentication',
['$rootScope', '$location', 'URL', '$http', '$q',
function ($rootScope, $location, URL, $http, $q) {
var myObject = {
authwithpwd: function (user) {
var dfd = $q.defer();
$http
.post('Mart2/users/login', {email: user.email, password: user.password})
.then(function (res) {
return dfd.resolve(res.data);
}, function (err) {
return dfd.reject(err.data);
});
return dfd.promise;
} //login
};
return myObject;
}]); //factory
And i'm using that service in user service as follows :
myApp.factory('UserService',
['$rootScope', '$location', 'URL', '$http', '$q', 'Authentication',
function ($rootScope, $location, URL, $http, $q, $Authentication) {
var myObject = {
login: function (user) {
$Authentication.authwithpwd(user).then(function (regUser) {
console.log(regUser);
}).catch(function (error) {
$rootScope.message = error.message;
});
},
getUserToken: function () {
return $rootScope.currentUser.apiKey;
},
isLogged: function () {
if ($rootScope.currentUser) {
return true;
} else {
return false;
}
}
//login
};
return myObject;
}]); //factory
I am very new to angular js . While writing service and calling that service from controller i have put a console debug in user service which is showing its returning object .i am getting object if i do console.log(regUser) ? any idea why ?

To get the object you need to do change your myObject declaration. Basically you need to return a promise from the login function and then write a callback to get the resolved data.
myApp.factory('UserService',
['$rootScope', '$location', 'URL','$http','$q','Authentication',
function($rootScope,$location, URL,$http,$q,$Authentication) {
var myObject = {
login: function(user) {
var defer = $q.defer();
$Authentication.authwithpwd(user).then(function(regUser) {
console.log(regUser);
defer.resolve(regUser);
}).catch(function(error) {
$rootScope.message = error.message;
defer.reject(regUser);
});
return defer.promise;
},
getUserToken:function() {
return $rootScope.currentUser.apiKey;
},
isLogged:function() {
if($rootScope.currentUser){
return true;
} else {
return false;
}
}//login
};
return myObject;
}]); //factory
To extract the object from controller or from some other service you need to write a callback
UserService.login(user)
.then(function (data) {
$scope.data = data;
}, function (error) {
$scope.error = error;
});
Also in the Authentication service you can just do a 'dfd.resolve' instead of 'return dfd.resolve'; since you are already returning the dfd.promise.
