Question

我正在使用的ejabberd模块，mod_pottymouth没有按预期过滤消息。添加日志记录后，我看到一个被调用的通用处理程序方法，而不是执行实际过滤的方法。问题是，我无法解析ejabberd消息以确保调用正确的函数。有人可以帮忙吗？

on_filter_packet({_From, _To, {xmlel, <<"message">>, _Attrs, Els} = _Packet} = _Msg) ->
  %This is what should be called to filter messages, but is never called
  FilteredEls = filterMessageBodyElements(Els, []),
  {_From, _To, {xmlel, <<"message">>, _Attrs, FilteredEls}};
on_filter_packet(Msg) ->
 % This is what actually gets called
 Msg.

这是使用ejabberd 17.01

Answer 1

从16.12开始，ejabberd不会路由xmlel个元素。您应该处理新的样式记录：message，presence或iq。请阅读https://docs.ejabberd.im/developer/guide/#ejabberd-router 和https://github.com/processone/xmpp/blob/master/README.md

所以，基本上，你的代码应该是这样的：

on_filter_packet(#message{body = Body} = Msg) ->
    NewBody = filterMessageBody(Body),
    Msg#message{body = NewBody};
on_filter_packet(Stanza) ->
    Stanza.

您是否尝试过将xmlel用作记录而不是元组？

预期的Ejabberd filter_packet函数未被调用
