【问题描述】：

我正在使用 ejabberd 15.09 并尝试创建一个模块来发送确认消息以换取收到的消息，我在路由此数据包时遇到错误。

错误日志：

2015-10-08 11:10:57.333 [错误] @ejabberd_sm:route:118 function_clause,[ejabberd_sm,do_route,[jid,>,>,>,>,>,>,jid,>,>,>,>,>,>,xmlelement,"message",["id",>,"type","Ack_receipt","from",>,"to",>],[xmlelement,"body",[],[xmlcdata,>]]],[file,"src/ejabberd_sm.erl",line,424],ejabberd_sm,route,3,[file,"src/ejabberd_sm.erl" ,line,116],ejabberd_local,route,3,[file,"src/ejabberd_local.erl",line,112],ejabberd_router,route,3,[file," src/ejabberd_router.erl",line,75],mod_ack,log_packet,3,[file,"src/mod_ack.erl",line,32],mod_ack,on_user_send_packet,4 ,[file,"src/mod_ack.erl",line,28],ejabberd_hooks,safe_apply,3,[file,"src/ejabberd_hooks.erl",line,385], ejabberd_hooks,run_fold1,4,[file,"src/ejabberd_hooks.erl",line,368]]

处理时： jid,>,>,>,>, >,>,jid,>,>,>, >,>,>,xmlelement,"message",["id",>,"type ","Ack_receipt","来自",>,"to", >],[xmlelement,"body",[],[xmlcdata,>]]

【参考方案1】：

您正在格式化xmlelement 记录。这种格式已过时。最新 ejabberd 上的数据包记录为 xmlel 记录。您需要更新代码以支持新格式。

记录格式说明如下：https://github.com/processone/xml/blob/master/include/xml.hrl
