Ejabberd-推送通知APNS和GCM与mod_offline_push

我试图得到与ejabberd工作的推送通知，我发现这个链接在这里：https://github.com/diamondbybold/ejabberd_mod_offline_post它应该在离线消息的URL发出POST请求。我编辑ejabberd.yml文件以包括URL和令牌，不过，我遇到了一些问题，试图在Ejabberd 16.12运行它时。它运行，但我将消息发送到离线的人，我看到下面的错误在/var/log/ejabberd/error.logEjabberd-推送通知APNS和GCM与mod_offline_push

内mod_offline_post.erl的，我有这样的功能：

offline_message(From, To, Packet) -> 
Type = fxml:get_tag_attr_s(<<"type">>, Packet), 
Body = fxml:get_path_s(Packet, [{elem, list_to_binary("body")}, cdata]), 
Token = gen_mod:get_module_opt(To#jid.lserver, ?MODULE, auth_token, fun(S) -> iolist_to_binary(S) end, list_to_binary("")), 
PostUrl = gen_mod:get_module_opt(To#jid.lserver, ?MODULE, post_url, fun(S) -> iolist_to_binary(S) end, list_to_binary("")), 

if 
    (Type == <<"chat">>) and (Body /= <<"">>) -> 
     Sep = "&", 
     Post = [ 
      "type=chat", Sep, 
      "to=", To#jid.luser, Sep, 
      "from=", From#jid.luser, Sep, 
      "body=", binary_to_list(Body), Sep, 
      "access_token=", Token 
     ], 
     ?INFO_MSG("Sending post request to ~s with body \"~s\"", [PostUrl, Post]), 
     httpc:request(post, {binary_to_list(PostUrl), [], "application/x-www-form-urlencoded", list_to_binary(Post)},[],[]), 
     ok; 
    true -> 
     ok 
end.

似乎人们能够通过在以后的版本中将xml更改为fxml来解决他们的问题，但它看起来并没有在我的情况下产生变化。

如果任何人有我如何解决实现推送通知的方式不同这有什么建议或想法，请让我知道。谢谢

由于16.12,Packet现在是一个#message{}记录，所以你应该使用xmpp库来处理它。

这里是你应该如何重写代码：

... 
-include("xmpp.hrl"). 
... 
offline_message(From, To, #message{type = Type, body = Body}) -> 
    BodyTxt = xmpp:get_text(Body), 
    ... 
    if (Type == chat) and (BodyTxt /= <<"">>) -> 
    ...

有关详情请咨询xmpp.erl和xmpp_codec.hrl。
