Not implemented, and it seems difficult to implement.

another question:
is there a way to send 2 or more stanzas to mod_rest without open another connection?
A single mod_rest request takes 1 msec with PHP, if i have to do 10 request it takes too much for a realtime purpose... maybe that with only 1 connection and many stanzas it will be faster.

It would be nice, but it is'nt immediately implementable, either.

Hi Badlop, is there any way

Hi Badlop,

is there any way to receive the stanza result from mod_rest?

is this an easy modify? or we can't because of an async process of stanzas... ?

thanks

PS:
i know about xmlrpc but mod_rest is more efficent and i have to handle pubsub

No idea, just some tests

Make sure you don't have any error message when ejabberd starts.

I configure loglevel to 5, and perform those tests in the same machine that has ejabberd installed.

$ cd ejabberd/src

$ erl

2> xmlrpc:call({127, 0, 0, 1}, 4560, "/", {call, user_resourcessssssss,

ejabberd.log only shows those messages, for command 1 and 2:

Then I try:

$ telnet 127.0.0.1 4560

And ejabberd.log shows:

Hi Again!

Hi Badlop,
thanks for your prompt response, i took you advice in consideration, and i installed ejabberd_xmlrpc with all its dependences, and i checked that am listening on the port 4560, but each time i submit a request i get the following:

=ERROR REPORT==== 2010-10-26 07:41:10 ===
{tcp_serv,139,{xmlrpc_http,handler,timeout}}

i checked my configurations and its all okay, i looked into the community but haven't found anyone in my case, how can i know if am sending the right command?
i tried sending many commands like:

xmlrpc:call({127, 0, 0, 1}, 4560, "/", {call, user_resources, [{struct, [{user, "testuser"}, {host, "localhost"}]}]}).

but i get the same result, the connection is not even accepted in the log.

mod_rest can send XMPP stanzas, but not receive them.

mod_rest can execute commands, receive a response and show it in the shell.

Another way to execute ejabberd commands and receive responses in your Python program is to install ejabberd_xmlrpc listener, and make XMLRPC calls instead of REST calls.

With that configuration, those commands work for me correctly.

Try to update mod_rest of SVN. I added some more detailed error reports, maybe they clarify what is your problem.

Thanks for your awesome fast reply :)

mod_rest not running

That strange error report probably indicates that you don't have mod_rest running in the vhost chat.mydomain.com.

You must have something like this in your ejabberd.cfg

{modules, [
  {mod_rest, []},
  ...
]}.

Go to ejabberd Web Admin -> Nodes -> your node -> Vhosts -> chat.mydomain.com -> Modules -> check that mod_rest is mentioned in that list.

I am a newbie to ejabberd..

I removed all the restrictions from mod_rest configurations,
Sent : "registered_users chat.mydomain.com"

still i get the following in log :

Another thing i need to verify, i read that i can query for all online users, so i send the following command:

i can see that the command is parsed and executed correctly, but how can i use this info? i mean i am supposed to receive it somewhere in the response , right? because i dont get anything except "OK", can i get it as xml? or response? or anything i can parse and use?

Thanks a lot!

Try a simple module

mfoss — Sun, 03 Oct 2010 21:26:54 +0000

Try a simple module configuration, without access restrictions:

  {mod_rest, []},

Execute a simple call, for example this python file:

import urllib2

server_url = 'http://localhost:5280/rest/'

call = 'register user1 localhost pass123'
resp = urllib2.urlopen(server_url, call)
result = resp.read()
print result

Execute it and you should get a valid response, and the account is registered

$ python aa.py
User user1@localhost successfully registered

$ ejabberdctl registered_users localhost
admin
user1

Once this simple configuration works, you can try to configure the access option and provide the access parameter in the call.
