python udp server parse and send received data to MySQL

Question

i am working on some proof of concept study research project and have python udp socket server that listen received data. Client send data NAME and FAMILY NAME on UDP to server. I would like to receive that data on UDP socket server side and on receive send this data to mysql database with two fields f_name and l_name.

import socket

UDP_IP = "192.168.1.10"
UDP_PORT = 9000

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.bind((UDP_IP, UDP_PORT))
print "UDP SERVER STARTED!"

while True:
    data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
    print "MSG Received:", data

this example is taken from web and with this server i get data on console. I would like to have it like below and of course code/concept can be changed. This might be solved with scapy sniffer but that would be dirty. Conceptually i would like to have ti something like: 1. socekt server received data 2. parse data received and send this data to mysql

I started with this in mind but doesnt work

import socket
import MySQLdb

UDP_IP = "192.168.1.10"
UDP_PORT = 9000

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.bind((UDP_IP, UDP_PORT))
print "UDP SERVER STARTED!"

while True:
    data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
    print "received message:", data

def parse(data):
    db = MySQLdb.connect("localhost","db_user","db_pass","directory_db")
    cursor = db.cursor()
    # Params to insert into DB
    f_nameObj = re.search(r'NAME: (.*?) .*', data, re.M|re.I)
    if f_name:
        f_name = f_nameObj.group(1)

    l_nameObj = re.search(r'SURNAME: (.*?) .*', data, re.M|re.I)
    if l_name:
        l_name = l_nameObj.group(1)

    # MySQL EXECUTION
    cursor.execute("""
    INSERT INTO dictionary (f_name, l_name) VALUES (%s, %s)""",(f_name,l_name))
    #
    db.commit()

With this kind of udp server i see no messages so seems function that parse data is not working with server. Any help or guidance would be appreciated

In your server when you receive data you don't call parse function.You just print the content of data . Add the line with the comment and see the result.

while True:
    data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
    print "received message:", data
    parse(data) # Call the Function
