Just a small snippet of python that forms a connection, sends some JSON, and outputs the response. Main use case is fast testing of OVSDB using a simple script.

JSONTest.py

import socket
import json
import time

def pingOVS(HOST, PORT):
	
	#Create socket
	s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

	#Establish TCP session via IP address and port specified
	s.connect((HOST, PORT))

	#Send JSON to socket
	print "Sending echo request =====>"
	s.send(json.dumps({'method':'echo','id':'echo','params':[]}))

	#Wait for response and print to console
	result = json.loads(s.recv(1024))
	print "<========" + str(result)
	time.sleep(2)

while True:
	pingOVS("10.12.0.30", 6634)

#Exit
s.close()
