Global Ajax error handler with AngularJS

When my website was 100% jQuery, I used to do this:

$.ajaxSetup({
global: true,
error: function(xhr, status, err) {
if (xhr.status == 401) {
window.location = "./index.html";
}
}
});

to set a global handler for 401 errors. Now, I use angularjs with $resource and $http to do my (REST) requests to the server. Is there any way to similarly set a global error handler with angular?

I'm also building a website with angular and I came across this same obstacle for global 401 handling. I ended up using http interceptor when I came across this blog post. Maybe you'll find it as helpful as I did.

"Authentication in AngularJS (or similar) based application.", espeo software

EDIT: final solution

angular.module('myApp', ['myApp.filters', 'myApp.services', 'myApp.directives'], function ($routeProvider, $locationProvider, $httpProvider) {


var interceptor = ['$rootScope', '$q', function (scope, $q) {


function success(response) {
return response;
}


function error(response) {
var status = response.status;


if (status == 401) {
window.location = "./index.html";
return;
}
// otherwise
return $q.reject(response);


}


return function (promise) {
return promise.then(success, error);
}


}];
$httpProvider.responseInterceptors.push(interceptor);

Please note that responseInterceptors have been deprecated with Angular 1.1.4. Below you can find an excerpt based on the official docs, showing the new way to implement interceptors.

$provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
return {
'response': function(response) {
// do something on success
return response || $q.when(response);
},


'responseError': function(rejection) {
// do something on error
if (canRecover(rejection)) {
return responseOrNewPromise;
}
return $q.reject(rejection);
}
};
});


$httpProvider.interceptors.push('myHttpInterceptor');

This is how it looks in my project using Coffeescript:

angular.module("globalErrors", ['appStateModule']).factory "myHttpInterceptor", ($q, $log, growl) ->
response: (response) ->
$log.debug "success with status #{response.status}"
response || $q.when response


responseError: (rejection) ->
$log.debug "error with status #{rejection.status} and data: #{rejection.data['message']}"
switch rejection.status
when 403
growl.addErrorMessage "You don't have the right to do this"
when 0
growl.addErrorMessage "No connection, internet is down?"
else
growl.addErrorMessage "#{rejection.data['message']}"


# do something on error
$q.reject rejection


.config ($provide, $httpProvider) ->
$httpProvider.interceptors.push('myHttpInterceptor')

Create the file <script type="text/javascript" src="../js/config/httpInterceptor.js" ></script> with this content:

(function(){
var httpInterceptor = function ($provide, $httpProvider) {
$provide.factory('httpInterceptor', function ($q) {
return {
response: function (response) {
return response || $q.when(response);
},
responseError: function (rejection) {
if(rejection.status === 401) {
// you are not autorized
}
return $q.reject(rejection);
}
};
});
$httpProvider.interceptors.push('httpInterceptor');
};
angular.module("myModule").config(httpInterceptor);
}());
