Wie schicke ich eine Nachricht vom Client zum Server in Python

Question

Ich lese 2 Programme in 2.7.10 mit Client und Server. Wie kann ich diese Programme ändern, um eine Nachricht vom Client zum Server zu senden?

#!/usr/bin/python   # This is server.py file 

import socket    # Import socket module 

s = socket.socket()   # Create a socket object 
host = socket.gethostname() # Get local machine name 
port = 12345    # Reserve a port for your service. 
s.bind((host, port))  # Bind to the port 

s.listen(5)     # Now wait for client connection. 
while True: 
    c, addr = s.accept()  # Establish connection with client. 
    print 'Got connection from', addr 
    c.send('Thank you for connecting') 
    c.close()    # Close the connection 




#!/usr/bin/python   # This is client.py file 

import socket    # Import socket module 

s = socket.socket()   # Create a socket object 
host = socket.gethostname() # Get local machine name 
port = 80    # Reserve a port for your service. 

s.connect((host, port)) 
print s.recv(1024) 
s.close      # Close the socket when done

TCP-Sockets sind bidirektional. So, nach dem Anschluss gibt es keinen Unterschied zwischen Server und Client ist, müssen Sie nur an den Enden eines Stroms:

import socket    # Import socket module 

s = socket.socket()   # Create a socket object 
s.bind(('0.0.0.0', 12345))  # Bind to the port 

s.listen(5)     # Now wait for client connection. 
while True: 
    c, addr = s.accept()  # Establish connection with client. 
    print 'Got connection from', addr 
    print c.recv(1024) 
    c.close()    # Close the connection 

und den Kunden:

import socket    # Import socket module 

s = socket.socket()   # Create a socket object 
s.connect(('localhost', 12345)) 
s.sendall('Here I am!') 
s.close()      # Close the socket when done
