ejabberd -自定义iq处理程序

Question

我已经创建了简单的模块。以下是代码

-module(mod_conversations).
-behaviour(gen_mod).
-export([start/2, stop/1, process_local_iq/3]).
-include("ejabberd.hrl").
-include("logger.hrl").
-include("jlib.hrl").
-define(IQ_CUSTOM, <<"jabber:iq:conversations">>).
start(Host, _) ->
    gen_iq_handler:add_iq_handler(ejabberd_local, Host, ?IQ_CUSTOM, ?MODULE, process_local_iq, one_queue),
ok.
stop(Host) ->
    gen_iq_handler:remove_iq_handler(ejabberd_local, Host, ?IQ_CUSTOM),
ok.
process_local_iq(From,_ ,IQ) ->
IQ#iq{type = result, sub_el = [{xmlelement, <<"value">>, [], [{xmlcdata, <<"Testing...">>}]}]}.

当我使用strophe.js var iq = $iq({type: 'get', to: 'some host'}).c('query', {xmlns: 'jabber:iq:conversations'}); connection.sendIQ(iq);发出请求时

服务器断开了我的连接。我试图找到类似的问题，但其中一些问题更严重。请帮我解决这个问题

在ejabberd的最新版本中不能使用xmlelement元组，正确的代码应该如下所示：

IQ#iq{type = result,
      sub_el = [#xmlel{name = <<"value">>,
                       children = [{xmlcdata, <<"Testing...">>}]}]}.
