websocket send command

juntiedt

I am experimenting with websocket send. I want to replace the hard coded command with variables. Unfortunately without success. See code:

import websocket
import json
from time import *


#sending messages ------------------------------------

def send_data(CMD,DEV,CIRCUIT,VALUE):
    print("sending data : ",CMD,DEV,CIRCUIT,VALUE)
    x = ("%s" %('"cmd"' + ":" + '"' + CMD + '"' + "," + '"dev"' + ":" + '"' + DEV + '"' + "," + '"circuit"' + ":" + '"' + CIRCUIT + '"' + "," + '"value"' + ":" + '"' + VALUE + '"'))
    print(x)
    ws = websocket.WebSocket()
    ws.connect("ws://localhost/ws")
    #ws.send('{"cmd":"all"}')
    #ws.send('{"cmd":"set","dev":"relay","circuit":"3","value":"0"}')
    ws.send('{("%s" %('"cmd"' + ":" + '"' + CMD + '"' + "," + '"dev"' + ":" + '"' + DEV + '"' + "," + '"circuit"' + ":" + '"' + CIRCUIT + '"' + "," + '"value"' + ":" + '"' + VALUE + '"'))}')    
    #ws.send('{"%s" %(x)}')
    ws.close()

#main program -----------------------------------------
#
send_data("set","relay","5","1")
sleep(10)

Any idea what I am doing wrong here?
Also command "cmd":"all" is not working.

I am running evok on Stretch. Are there still problems with the new os?
I find it difficult to find the needed libraries for stretch and Python3. It would be helpfull to have some tested links for download.

appriciate your help.

I found it:

#sending messages
def ws_send(CMD, DEV, CIRCUIT, VALUE):
    ws = websocket.WebSocket()
    ws.connect(url)
    ws.send('{"cmd":"%s","dev":"%s","circuit":"%s","value":"%s"}' %(CMD,DEV,CIRCUIT,VALUE))    
    ws.close()
