deferred - AngularJS Handle different error codes in different places -

i have service contains generic call $http ajax calls uses. here have "centralized" error handling status codes results in redirects.

"fieldssync" service:

return $http({     method: 'post',     url: url,     data: $.extend(defaultpostdata, postdata) }).error(function(data, status) {     switch (status) {         case 401: // "unauthorized". not logged in.              redirect.tologinpage();             break;         case 403: // "forbidden". role has changed.             redirect.tologoutpage();             break;     } }); 

when calling 1 of service functions controller return deferred object able hook more error callbacks able handle errors should result in kind of feedback user.

controller:

fieldssync.createfield(newfield).success(function(data) {     ... }).error(function(data, status) {     switch (status) { // <--- not want         case 401:         case 403:             return; // these errors handled (=redirects) in generic error callback , don't want show while redirects.     }     ... // "individual" error handling. =displaying messages , stuff }); 

but because don't want error messages popping before redirect occurs have exit error callback if status codes have been handled.

the question is: how rid of switch cases in controllers? possible exit chain of error callbacks when specific error code has been handled? or possible work around in less ugly way? :)

this reoccurring problem me, , mind seems stuck.

i have checked docs , cant find pretty solution in either $http or $q.

i propose use responseinterceptor handle cases:

http://docs.angularjs.org/api/ng.$http

i wrote following, when had same "problem" you. first draft, can improve needs

internalservererrorresponseinterceptor = function($q, internalservererrorservice) {     return function(promise) {         return promise.then(function(response) {             return response;         }, function(response) {             if (response.status > 499) {                 internalservererrorservice.handleerror();                 return $q.reject(response);             }             return $q.reject(response);         });     }; }; module.factory('internalservererrorresponseinterceptor', ['$q', 'internalservererrorservice', internalservererrorresponseinterceptor]); module.config(['$httpprovider', function($httpprovider) {         $httpprovider.responseinterceptors.push('internalservererrorresponseinterceptor');     }]); 

now specific internalservererrorservice can handle way want handled :)
