sudhansu · November 11th, 2012, 05:38 PM

I am doing the one to one chat by referring ch06 example.

Test Case1: logged in as two user as UserA and UserB. UserA send first message , it is successfully received and shown in UserB but if again UserA sends another messges it is not showing.

Any urgent help will be great.

I'll need the wire logs of what is getting sent and received over the XMPP connection. See the examples in Chapter 4 for how to produce those (rawInput()/rawOutput).

sudhansu · November 12th, 2012, 04:32 AM

Below are the raw inputs.

1. UserA Sends the below message to UserB
<message to='[email protected]' type='chat' xmlns='jabber:client'><body>dd</body></message>

2. UserB is able to recieve the message body and show out put as "dd".

3. Again UserA sends the below message to UserB
<message to='[email protected]' type='chat' xmlns='jabber:client'><body>ssss</body></message>

4.But this time UserB does not recieve any thing.

I did some change to send you the actual rawinput.

******Below is raw input which UserA([email protected]/5180c0a5) sends to UserB ([email protected])*****************

By executing the CH4 i am getting this output and it seems that the message packets are not lost and received properly. But I am not able understand why the below is not working.

var full_jid = $(message).attr('from');
alert(full_jid);
var uname = Strophe.getNodeFromJid(full_jid);

var body1 = $(message).find('body');

Please help me in this case as it is very urgent to me.

Your handle_message isn't returning true. If it doesn't return true it is removed from the handler list after it processes that event.

The messages are being received, it's just that your handler isn't called anymore after the first one. Add 'return true;' to the end of your handler and it should work as you expect.

sudhansu · November 12th, 2012, 03:29 PM

Hi,

First of all many thanks for your help , it seems to be working. Also kindly can you let me know how we can show offline messages, and time stamp of each message when it was send.

Thanks

metajack · November 12th, 2012, 04:09 PM

Glad it's working now.

Offline messages will get sent with a delayed delivery tag. You can read more about those here:
http://xmpp.org/protocols/urn_xmpp_delay/

sudhansu · November 12th, 2012, 04:41 PM

is that delayed tag will be formed automatically by XMPP or we have to send it explicitly. Also please let me know how we can get the time stamp while receiving a message.

Thanks

metajack · November 12th, 2012, 04:45 PM

The delayed tag is automatically added by the server's offline message processing.

You can pull out the timestamp just as you would any other XML data. $(msg).find('delay').attr('stamp') for example.

sudhansu · November 13th, 2012, 03:18 PM

is there any way where I can also see the time stamp of normal messgaes rather than just for offline messages?

Means can I do something like $(msg).find('body').attr('stamp')

sudhansu · November 14th, 2012, 03:32 PM

I am new to xmpp so any help to my above question will be very helpful for me.
