How to execute http delete in angularjs?

Question

Angular

Hello. I can't figure out how to execute a delete type request in angularjs. The server has a rest api, it waits for two input parameters. I do it like this:

$http.delete('http://api/v1/contacts/index/', {params: {id_user: $localStorage.userAuthData.id_user, id_contact: id_contact}})
      .success(function(data)
      {
}
      });

but nothing works. After serializing the data, they are simply substituted into the url, but this is wrong in my opinion. Please tell me.
PS On the codeigniter rest api server.
The method itself:

function index_delete()
  {
    $id_user = $this->delete("id_user");
    $id_contact = $this->delete("id_contact");

    if (!empty($id_user) && !empty($id_contact))
    {
      if ($id_user == $this->data_token->id_user)
      {
        $data_contacts = array(
          'id_user' => $id_user,
          'id_contact' => $id_contact
          );
        if ($this->contacts_model->delete_contact($data_contacts))
        {
          $data_response = array(
            'status' => 'success',
            'response' => $data_contacts
            );
          $this->response($data_response, 200);
        } 
        else 
        {
          $data_response = array(
            'status' => 'failed',
            'response' => 'Error delete contact.'
            );
          $this->response($data_response, 500);
        }
      }
      else 
      {
        $data_response = array(
          'status' => 'failed',
          'response' => 'User with the token does not exist.'
        );
        $this->response($data_response, 404);
      }
    }
    else 
    {
      $data_response = array(
        'status' => 'failed',
        'response' => 'Data were not obtained or is not valid.'
        );
      $this->response($data_response, 500);
    }
  }

Судя по документации angular всё делает правильно, т.к. передача тела для DELETE запроса не определена:
Принимайте ваши параметры из строки запроса на стороне сервера.
