AngularJS Intercept all $http JSON responses

You can intercept responses by adding an interceptor to $httpProvider.interceptors with Angular 1.1.4+ (see documentation here search for interceptors).

For a specific content type like json you can potentially reject changes or throw an exception even if the call was a success. You can modify the response.data that will get passed to your controller code as well here:

myModule.factory('myHttpInterceptor', function ($q) {
    return {
        response: function (response) {
            // do something on success
            if(response.headers()['content-type'] === "application/json; charset=utf-8"){
                // Validate response, if not ok reject
                var data = examineJSONResponse(response); // assumes this function is available

                if(!data)
                    return $q.reject(response);
            }
            return response;
        },
        responseError: function (response) {
            // do something on error
            return $q.reject(response);
        }
    };
});
myModule.config(function ($httpProvider) {
    $httpProvider.interceptors.push('myHttpInterceptor');
});

NOTE: Here is the original answer for versions prior to 1.1.4 (responseInterceptors were deprecated with Angular 1.1.4):

Maybe there's a better way but I think you can do something similar to this post with the http response interceptor (described here) (for a specific content type like json) where you potentially reject changes or throw an exception even though the call was a success. You can modify the response.data that will get passed to your controller code as well here.

myModule.factory('myHttpInterceptor', function ($q) {
    return function (promise) {
        return promise.then(function (response) {
            // do something on success
            if(response.headers()['content-type'] === "application/json; charset=utf-8"){
                // Validate response if not ok reject
                var data = examineJSONResponse(response); // assumes this function is available

                if(!data)
                    return $q.reject(response);
            }
            return response;
        }, function (response) {
            // do something on error
            return $q.reject(response);
        });
    };
});
myModule.config(function ($httpProvider) {
    $httpProvider.responseInterceptors.push('myHttpInterceptor');
});

Another solution is to create a service and use that around the $http variable.

angular.module('App', [])
  .factory('myHttp',['$http',function($http) {
    return function(url, success, failure) {
      $http.get(url).success(function(json) {
          var data = examineJSONResponse(json);
          data && data.success ? success() : failure();
        }).error(failure);
      );
    }
}]);

And now this can be called like:

myHttp(url, onSuccess, onFailure);
