Python网络/套接字编程，简单的游戏

Question

Im trying to make a simple game but cant understand how to make it work and send more then one thing over the network. It works the first time but it supposed to go 10 times. It only sends 1 random number now but i want it to send one new when the game goes again and want a new number.

Server

import socket, random               

sock = socket.socket()
host = socket.gethostname()
port = 12345
sock.bind((host, port))
sock.listen(5)

c, addr = sock.accept()

cpu = random.choice(range(0, 3))
c.send(cpu)

gameon = c.recv(int(1024))

Client

import socket, random

sock = socket.socket()  # Create a socket object
host = socket.gethostname()  # Get local machine name
port = 12345  # Reserve a port for your service.
sock.connect((host, port))

GAMEON = 'Rock', 'Paper', 'Scissors'
game = 0
iwin = 0
ilose = 0
tie = 0

while game < 10:

    for i in range(0, 3):
        print "%d %s" % (i + 1, GAMEON[i])

    player = int(input ("Choose from 1-3: ")) - 1
    cpu = int(sock.recv(1024))
    print cpu

    print""

    print "%s vs %s" % (GAMEON[player], GAMEON[cpu])
    print ""
    if cpu != player:
      if (player - cpu) % 3 < (cpu - player) % 3:
        print "Player wins\n"
        iwin += 1
      else:
        print "CPU wins\n"
        ilose += 1
    else:
      print "TIE!\n"
      tie += 1 
    game += 1
    sock.send(str(game))
print"Game is done"
print"you win: ", (iwin), "Times"
print"computer wins: ", (ilose), "Times"
print"tie: ", (tie), "Times"

You need threads to do your bidding.

Example code

# Listen
s.listen(10)
print 'Socket now listening on port ' + str(PORT) + "..."

while 1:
    # wait
    conn, addr = s.accept()

    print 'Connected with ' + addr[0] + ":" + str(addr[1])

    # Let's fork a thread for each request
    processThread = threading.Thread(target=processConnection, args=(conn, addr[0]));
    processThread.start()


s.close()

Your processConnection will look like this:

# Process Connection
def processConnection(conn, ip):
    print "Thread started..."
    print "-------------------------------------------------------------";

    cpu = random.choice(range(0, 3))
    conn.send(cpu)

    gameon = conn.recv(int(1024))

    conn.close()

Update 1

If you need the server to keep talking with the client, then do this. Server will wait for the client to send back a message. If client sends anything, server will return a random number. If the client doesn't need anymore data, just close the connection and server loop will end.

import socket, random               

sock = socket.socket()
host = socket.gethostname()
port = 12345
sock.bind((host, port))
sock.listen(5)

c, addr = sock.accept()

white True:
    cpu = random.choice(range(0, 3))
    c.send(cpu)

    gameon = c.recv(int(1024))

    if gameon is None:
        break

The problem is that your server will serve one request and then stop. You need to put it in some kind of while loop.
