XMPPFramework - Retrieve Archived Messages From Openfire Server

Solution 1:

You have to do a request with <retrieve> (see http://xmpp.org/extensions/xep-0136.html) then you can take a specific time from the received <list> result. For example:

Send:

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

Receive:

 <iq type="result" id="pk1" to="vivek@openfire/iphone">
     <list xmlns="urn:xmpp:archive">
      <chat with="piyush@openfire" start="2012-07-04T13:16:12.291Z"/>
      <chat with="piyush@openfire" start="2012-07-05T08:25:31.555Z"/>
      <chat with="piyush@openfire" start="2012-07-05T12:38:24.098Z"/>
      <set xmlns="http://jabber.org/protocol/rsm">
          <first index="0">15</first>
           <last>25</last>
           <count>3</count>
      </set>
    </list>
 </iq>

Now you choose one of starts and send (date and hour must be exacts):

  <iq type='get' id='pk1'>
    <retrieve xmlns='urn:xmpp:archive'
        with='piyush@openfire''
        start='2012-07-04T13:16:12.291Z'>
     <set xmlns='http://jabber.org/protocol/rsm'>
       <max>100</max>
     </set>
    </retrieve>
 </iq>

You will receive something like this (depends the max value -> max=30, bodies=30):

   <iq type='result' to='vivek@openfire/iphone' id='page1'>
      <chat xmlns='urn:xmpp:archive'
             with='piyush@openfire'
              start='2012-07-04T13:16:12.291Z'
            subject='She speaks!'
       version='4'>
         <from secs='0'><body>Art thou not Romeo, and a Montague?</body></from>
         <to secs='11'><body>Neither, fair saint, if either thee dislike.</body></to>
          .
          [28 more messages]
          .
         <from secs='9'><body>How cam'st thou hither, tell me, and therefore?           </body>   
         </from>
      <set xmlns='http://jabber.org/protocol/rsm'>
       <first index='0'>0</first>
       <last>29</last>
       <count></count>
     </set>
  <iq>

Solution 2:

To retrieve the Specific time of chat

Send it to get the time:

 NSXMLElement *iq1 = [NSXMLElement elementWithName:@"iq"];
 [iq1 addAttributeWithName:@"type" stringValue:@"get"];
 [iq1 addAttributeWithName:@"id" stringValue:@"pk1"];
 NSXMLElement *retrieve = [NSXMLElement elementWithName:@"list" xmlns:@"urn:xmpp:archive"];
 [retrieve addAttributeWithName:@"with" stringValue:@"amit@openfire"];
 NSXMLElement *set = [NSXMLElement elementWithName:@"set" xmlns:@"http://jabber.org/protocol/rsm"];
 NSXMLElement *max = [NSXMLElement elementWithName:@"max" stringValue:@"100"];
 [iq1 addChild:retrieve];
 [retrieve addChild:set];


 [set addChild:max];


 [xmppStream sendElement:iq1];

To retrieve the Chat History

Use Start date and send:

 NSXMLElement *iq1 = [NSXMLElement elementWithName:@"iq"];
 [iq1 addAttributeWithName:@"type" stringValue:@"get"];
 [iq1 addAttributeWithName:@"id" stringValue:@"pk1"];

 NSXMLElement *retrieve = [NSXMLElement elementWithName:@"retrieve" xmlns:@"urn:xmpp:archive"];
 [retrieve addAttributeWithName:@"with" stringValue:@"amit@openfire"];
 [retrieve addAttributeWithName:@"start" stringValue:@"2013-11-18T05:11:53.460Z"];
 NSXMLElement *set = [NSXMLElement elementWithName:@"set" xmlns:@"http://jabber.org/protocol/rsm"];
 NSXMLElement *max = [NSXMLElement elementWithName:@"max" stringValue:@"100"];
 [iq1 addChild:retrieve];
 [retrieve addChild:set];
 [set addChild:max];
 [xmppStream sendElement:iq1];

Solution 3:

Firstly, to retrieve chat history from openfire you need install Open Archive plugin because Monitering Plugin is just for monitering and logging chat history at admin panel so once you will install Open Archive you won't get any error with code '500'.

You can download and learn to install Open Archive from the following links.

https://nexus.reucon.com/content/repositories/opensource-snapshots/com/reucon/openfire/plugins/archive/

https://maven.reucon.com/projects/public/archive/

Another issue in above code is that when you mention start tag in the request then it matches with the chat having the exact time stamp that's why it returns error code '404'. I ommited start tag from my request and wrote following code which returns whole chat history with the user.

NSXMLElement *iq1 = [NSXMLElement elementWithName:@"iq"];
[iq1 addAttributeWithName:@"type" stringValue:@"get"];
[iq1 addAttributeWithName:@"id" stringValue:@"pk1"];

NSXMLElement *retrieve = [NSXMLElement elementWithName:@"retrieve" xmlns:@"urn:xmpp:archive"];

[retrieve addAttributeWithName:@"with" stringValue:@"[email protected]"];
NSXMLElement *set = [NSXMLElement elementWithName:@"set" xmlns:@"http://jabber.org/protocol/rsm"];
NSXMLElement *max = [NSXMLElement elementWithName:@"max" stringValue:@"100"];

[iq1 addChild:retrieve];
[retrieve addChild:set];
[set addChild:max];
[[[self appDelegate] xmppStream] sendElement:iq1];

Here this will return whole chat history in XML response between user Rahul and the user currently logged in.
