如何在android中从开火中检索聊天记录

Question

我有一个聊天应用程序，我想在其中检索两个用户之间的聊天历史记录，我有一个用于检索聊天消息的节，那就是...

    <iq type='get' id='pk1'>
<list xmlns='urn:xmpp:archive'
with='shrey27@sys1-pc'>
<set xmlns='http://jabber.org/protocol/rsm'>
<max>30</max>
</set>
</list>
</iq>

现在，我的问题是如何将这节发送到服务器，以便获得响应。我已经安装了消息归档插件，并且消息正在完美地存储。任何建议都会是有益的...... 提前致谢！！！

NSXMLElement *iQ = [NSXMLElement elementWithName:@"iq"];
[iQ addAttributeWithName:@"type" stringValue:@"get"];
[iQ addAttributeWithName:@"id" stringValue:@"987654321"];

NSXMLElement *list = [NSXMLElement elementWithName:@"list"];
[list addAttributeWithName:@"xmlns" stringValue:@"urn:xmpp:archive"];
[list addAttributeWithName:@"with" stringValue:@"bhushan@mydomain.com"];



NSXMLElement *set = [NSXMLElement elementWithName:@"set"];
[set addAttributeWithName:@"xmlns" stringValue:@"http://jabber.org/protocol/rsm"];

NSXMLElement *max = [NSXMLElement elementWithName:@"max"];
[max addAttributeWithName:@"xmlns" stringValue:@"http://jabber.org/protocol/rsm"];
max.stringValue = @"30";

[set addChild:max];

[list addChild:set];
[iQ addChild:list];
[[[self appDelegate] xmppStream] sendElement:iQ];

你可以这样打电话。希望这会有所帮助:)
