javascript - AngularJS $http and how to get error response -

i see following example calling server-side resource:

usersession.prototype.$save = function() {     return $http.post('/users/sign_in', {       "user" : {          "email" : this.email,         "password" : this.password,         "remember_me" : this.remember_me ? 1 : 0        }        });    };   

my question is, possible see actual error response in code in event call fails? how above written that?

you missed callbacks

usersession.prototype.$save = function() {     return $http.post('/users/sign_in', {       "user" : {          "email" : this.email,         "password" : this.password,         "remember_me" : this.remember_me ? 1 : 0        }        })     .success(function (data, status, headers, config) {        // success logic here     })     .error(function (data, status, headers, config) {        // error logic here     }); };
