Re: [spade-users] Agent Communication: Sending and Receiving Messages doesn't work

[Markus Schatten]

Hello!

Yes, the example is missing an additional instance of behaviour, e.g. something like:

ab = self.AnotherBehav()

Hope this helps!

Best,

M.

thank you for the help. I already tried to add ab = self.AnotherBehav() but it seems not working.

Hi,

it works fine for me... How did you test it?

Did you first run:

configure.py localhost

and then:

runspade.py

?

If yes, did you send a "cooking" message from the admin interface, e.g. http://localhost:8008?

I am getting the expected output for various messages...

$ python test.py
I got a message!

I got a cooking message!
I got a cooking message!

I got a message!

Best,

M.

Hello,

Thank you for the help. I do this steps configure.py localhost and then: runspade.py. But I don't understand how can I send  send a "cooking" message from the admin interface, e.g. http://localhost:8008?. 

Another question Can I send a message from a simple python  program to the agent. I yes how can I dot it?

Best,

[Markus Schatten]

Hi,

to send a "cooking" message from the administrative interface go to;

http://localhost:8008/agents (password is "secret")

Click on the "Send Msg" button right of your agent. Then enter
"cooking" into the "Ontology" field of the message and send it.

Of course you can send messages from Python scripts, this is the
intention of MAS ;-)

Create another script like (haven't tested it, but should work):

#!/usr/bin/env python
# -*- coding:utf-8 -*-

import spade

sender = spade.Agent.Agent( 'sen...@127.0.0.1', 'password' )

receiver = spade.AID.aid( name="rece...@127.0.0.1", addresses=[
"rece...@127.0.0.1" ] )
msg = spade.ACLMessage.ACLMessage()
msg.setPerformative( "inform" )
msg.setOntology( "cooking" )
msg.addReceiver( receiver )
msg.setContent( "hello" )
sender.send( self.msg )


Where receiver is the other agent...

hth

Best,

M.
