The use of $q in that situation isn't really needed. You could do something
like
authenticate: function (url, user) {
return $http.post(url,user).then(function(response){
console.log(response);
return response;
});
}
That will return a promise that console.logs its response and still
resolves to that response. You can delete the .then entirely. Either way,
in your application logic you could do:
AuthenticateService.authenticate(url,user).then(function(response) {
//note that this is the 'success' state
$scope.view.username = response.data.username;
//etc etc
}).catch(function(err) {
// the $post returned a non 200 value
console.log('ERROR authenticating!');
console.log(err);
});
Of course, just having a function that returns a $http.post is a bit of an
over-abstraction. You could just put the $http on your controller too. On
the other hand, most of the time you're not *just* doing the $http.post in
the authenticate service. You could modify that to do
authenticate: function(user) {
//we can keep the service URL local so it's only changed in one place
return $http.post(knownBackendUrl,user).then(function(response) {
//deal with response.data here and create a
// user object to return that's more abstracted
}).catch(function(err) { // also do error handling
});
Then it's more worthwhile.
