我正在尝试使用 iOS 中的 XMPPFramework 和 OpenFire 服务器来实现聊天应用程序。我的聊天工作正常，我正在尝试从服务器检索聊天历史记录。当然，我已经在服务器上启用了邮件存档。这是我发送的请求
<iq type="get">
<retrieve xmlns="urn:xmpp:archive" with="dev_user80@mydomain">
<set xmlns="http://jabber.org/protocol/rsm">
<max>100</max>
</set>
</retrieve>
</iq>
这是我得到的回应。
<iq xmlns="jabber:client" type="error" to="dev_user103@mydomain/6i0qoo9tek">
<retrieve xmlns="urn:xmpp:archive" with="dev_user80@mydomain">
<set xmlns="http://jabber.org/protocol/rsm">
<max>100</max>
</set>
</retrieve>
<error code="503" type="cancel">
<service-unavailable xmlns="urn:ietf:params:xml:ns:xmpp-stanzas">
</service-unavailable>
</error>
</iq>
我已经浏览了在互联网上可以找到的所有解决方案，但找不到令人满意的解决方案
change urn:xmpp:archive to urn:xmpp:archive:auto
我遇到了同样的问题，并通过运行发现请求确定了这一点：http://xmpp.org/extensions/xep-0136.html#disco
我发了这个智商：
<iq from='[email protected]'
id='disco1'
to='mydomain.com'
type='get'>
<query xmlns='http://jabber.org/protocol/disco#info'/>
</iq>
我启用了监控插件的 Openfire 服务器返回了以下结果：
<iq xmlns="jabber:client" type="result" id="disco1" from="mydomain.com" to="[email protected]/resource">

您可以看到自动存档（urn:xmpp:archive:auto）和档案管理（urn:xmpp:archive:manage）支持，但手动存档（urn:xmpp:archive:manual) 和存档首选项 (urn:xmpp:archive:pref） 不是。
还支持 XEP-0313（列为urn:xmpp:mam:0）并可以检索存档的消息：http://xmpp.org/extensions/xep-0313.html
