Is there a way to call a function every time after a response is returned from a server without explicitly calling it after in the callback?
The main purpose is that I do have a generic error handler service that I call in every request's callback and I want to specify it somewhere and it shall be called automatically.
I gave Gloopy a +1 on solution, however, that other post he references does DOM manipulation in the function defined in the config and the interceptor. Instead, i moved the logic for starting spinner into the top of the intercepter and I use a variable in the rootscope to control the hide/show of the spinner. It seems to work pretty well and I believe is much more testable.
<img ng-show="polling" src="images/ajax-loader.gif">
angular.module('myApp.services', ['ngResource']).
.config(function ($httpProvider) {
$httpProvider.responseInterceptors.push('myHttpInterceptor');
var spinnerFunction = function (data, headersGetter) {
return data;
};
$httpProvider.defaults.transformRequest.push(spinnerFunction);
})
//register the interceptor as a service, intercepts ALL angular ajax http calls
.factory('myHttpInterceptor', function ($q, $window, $rootScope) {
return function (promise) {
$rootScope.polling = true;
return promise.then(function (response) {
$rootScope.polling = false;
return response;
}, function (response) {
$rootScope.polling = false;
$rootScope.network_error = true;
return $q.reject(response);
});
};
})
// other code left out
If you mean for requests using $http or a $resource you can add generic error handling to responses by adding code to the $httpProvider.responseInterceptors. See more in this post.
Although it is about starting/stopping spinners using this fiddle you can add your code in the 'stop spinner' section with // do something on error. Thanks to zdam from the groups!
