Injecting $http into angular factory($exceptionHandler) results in a Circular dependency

Question

When I try inject $http into an overridden factory I get the error:

Uncaught Error: [$injector:cdep] Circular dependency found: $http <- $exceptionHandler <- $rootScope

AngularModule.factory('$exceptionHandler',  function ($http) {

any ideas how to resolve? if I inject using [], $http is undefined

edit__________________

as per an answer below I tried:

MyModule.config(function($provide, $http) {
    $provide.decorator("$exceptionHandler", function($delegate) {
        return function(exception, cause) {..

but I still get the circular error:

Uncaught Error: [$injector:cdep] Circular dependency found: $http <- $exceptionHandler <- $rootScope

Answer 1

Inject the $injector and then get the $http service from there. Something like this:

AngularModule.factory('$exceptionHandler',  function ($injector) {
    var $http = $injector.get("$http");

See https://groups.google.com/forum/#!topic/angular/lbFY_14ZtnU/discussion

However, this will completely override the $exceptionHandler functionality provided by Angular. If you just want to add the server-side log to the existing functionality, see this question about augmenting $exceptionHandler functionality.

Answer 2

I'm using this solution, because of circular dependency issues with rootScope:

angular
  .module('facilityLog')
  .provider('$exceptionHandler', function() {
 "use strict";

 this.$get = function($injector) {

  function exceptionHandler(exception, cause) {
   // This is the part where you get the instance of $http in your case
   var $rootScope = $injector.get('$rootScope');
   //...
  }

  return exceptionHandler;

}});

So if you request the instance inside the exceptionHandler-Function you will not get the circular dependency-error.

I used the following to solve this. Note how the array notation is used to make this minification safe. Note also, that I am completely overriding the $esceptionHandler and using my own service to replace it.

angular
    .module('app')
    .factory('$exceptionHandler', $exceptionHandler);

$exceptionHandler.$inject = ['$injector', 'exceptionLoggingService'];

function $exceptionHandler($injector, exceptionLoggingService)
{
    return function(exception, cause)
    {
        exceptionLoggingService.http = exceptionLoggingService.http || $injector.get('$http');
        exceptionLoggingService.error(exception, cause);
    };
}
