我已经配置了ejabberd 14.12服务器，启用了多会话和工作mod_mam（XEP-0313 v0.2，https://github.com/kongo2002/ejabberd-mod-mam，http://xmpp.org/extensions/attic/xep-0313-0.2.html）
当我通过一个会话将来自一个连接会话的用户发送给不同用户的消息
时，mod_mam效果很好但是，如果user-1 @ example有2个具有不同资源的在线会话，则user-2 @ example发送给user-1 @ example（对于裸JID）一条消息 - mod_mam保存两条消息

我们可以从mod_mam看到双'handle_cast'。
当我从档案中查询消息时，我得到了类似的内容：

</message>
</forwarded>
</result>
</message>
但我想只收到一条没有重复的邮件。
类似地，如果user-1 @ example有3个具有不同资源的在线会话，而user-2 @ example发送给user-1 @ example（到裸JID）一条消息 - mod_mam保存两条消息。

答案 0 :(得分：0)
根据XMPP MAM规范，如果您不想从所有资源获取消息，则看起来您需要查询完整的JID（使用资源）。这似乎是正确的行为。
答案 1 :(得分：0)
来自ejabberd-contrib的mod_mam非常完美。问题解决了。
