TCP Communication
Client - Here's simple code to send and receive data by TCP in Python:
#!/usr/bin/env pythonimport socketTCP_IP = '127.0.0.1'TCP_PORT = 5005BUFFER_SIZE = 1024MESSAGE = "Hello, World!"s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)s.connect((TCP_IP, TCP_PORT))s.send(MESSAGE)data = s.recv(BUFFER_SIZE)s.close()print "received data:", data
Server - Here's simple code to serve TCP in Python:
#!/usr/bin/env pythonimport socketTCP_IP = '127.0.0.1'TCP_PORT = 5005BUFFER_SIZE = 20 # Normally 1024, but we want fast responses = socket.socket(socket.AF_INET, socket.SOCK_STREAM)s.bind((TCP_IP, TCP_PORT))s.listen(1)conn, addr = s.accept()print 'Connection address:', addrwhile 1: data = conn.recv(BUFFER_SIZE) if not data: break print "received data:", data conn.send(data) # echoconn.close()
