【问题描述】：

我正在开发一个 ios 项目中的 XAMPP。 我想在哪里获取所有注册用户..

下面是我使用的代码：-

NSError *error = [[NSError alloc] init];

NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@"http://jabber.org/protocol/disco#items' node='all users'/>" error:&error];

XMPPIQ *iq = [XMPPIQ iqWithType:@"get" to:[XMPPJID jidWithString:@"DOMAIN"]

[appDel_friends.xmppStream sendElement:iq];

我得到一个错误错误代码 404 item not found。

请求：

SEND: <iq type="get" to="ios.ioschat.com" id="44BF120A-83F5-4AB8-85AD-006D752B716E"><query xmlns="http://jabber.org/protocol/disco#items" node="all users"/></iq>

回复：-

 RECV: <iq xmlns="jabber:client" type="error" id="44BF120A-83F5-4AB8-85AD-006D752B716E" from="ios.ioschat.com" to="[e-mail]/1661f8e6"><query xmlns="http://jabber.org/protocol/disco#items" node="all users"/><error code="404" type="cancel"><item-not-found xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error></iq>

请帮帮我..

【参考方案1】：

试试这个

在视图中确实加载设置了这个

 [defaults setObject:@"your mid" forKey:@"kXMPPmyJID"];
   [defaults setObject:@"your password" forKey:@"kXMPPmyPassword"];
    [defaults synchronize];
