Question

我现在正在使用ejabberd作为聊天服务器。我正在写一个客户聊天和注册新用户。现在，我知道一些注册新帐户的协议，比如发送以下命令来注册新用户：

<iq type="set"><query xmlns="jabber:iq:register"><username>wfwfewegwegwewefg</username><password>wfwefwefwefwef</password></query></iq>

我的问题是：我想学习更多的命令/协议来与服务器通信。那我在哪里可以了解更多？例如，如何询问服务器是否存在用户名。如何让服务器取消注册用户。

我应该搜索的关键词是什么？我应该搜索Jabber XMPP协议还是什么？

Answer 1

如果您要从管理员帐户发送查询来执行这些操作，请查看基于XEP-0133: Service Administration的XEP-0050: Ad-hoc commands。

如果从一般用户的角度来看你的意思更多，那么你通常无法看到用户帐户是否存在（这会让垃圾邮件发送者将其用于目录收集），但你可以XEP-0077: In-band Registration。

http://xmpp.org/extensions/还有更多针对各种事物的标准扩展 - 有些正在开发中，有些已经完成并且稳定。

如果您使用ejabberd，则可以使用命令行实用程序ejabberdctl来解决您的问题。

我发现这本书"XMPP: The Definitive Guide"对于概述协议及其术语非常有用。之后的XEP很好作为参考。
