XMPP：Ejabberd 未将具有命名空间前缀的自定义 IQ 转发给用户

【中文标题】XMPP：Ejabberd 未将具有命名空间前缀的自定义 IQ 转发给用户

【英文标题】：XMPP: Ejabberd not forwarding custom IQ with namespace prefix to user

【发布时间】：2013-09-11 12:52:11

【问题描述】：

我必须使用我自己的命名空间 http://www.test.com/test 从 eva@pc377/Smack 向特定用户 bob@pc377/Smack 发送自定义 IQ。当我使用 OpenFire 时一切正常，但 Ejabberd 不会将此 IQ 转发给用户。在我看到的日志文件中，IQ 由服务器接收，内部分派给会话管理器，但未转发给用户。如果我发送Message，它会被正确转发。我正在使用基于 Java 的 Smack-Client。

Ejabberd 是否需要特定配置来转发自定义 IQ？

【参考方案1】：

用更简单的 XML 试试：

<iq id="0j8w6-8" to="bob@pc377/Smack" type="set">
    <register-request xmlns="http://www.test.com/test">
       <node-id>550e8400-e29b-11d4-a716-446655440000</node-id>
       <properties>
          <path>.</path>
          <delivery-mode>1</delivery-mode>
       </properties>
   </register-request>
</iq>

如果这不起作用，请尝试重命名 register-request 和 delivery-mode 以删除破折号。这些更改都不是必需的，但任何一个都可以帮助 ejabberd 团队找到错误。

【讨论】：

好建议...我试过了，智商转发！经过一些测试，在我看来 ejabberd 无法处理 XML 中的命名空间前缀。

我已经提交了一个错误报告。可以在这里找到：support.process-one.net/i#browse/EJAB-1661
