Python聊天室程序---基础

客户端代码：

# Filename: socketClient.py

import socket
import sys
import threading

# Client GUI
from tkinter import *
import Pmw



# Create a TCP/IP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# Connect the socket to the port where the server is listening
server_address = ('localhost', 10000)
print (sys.stderr, 'connecting to %s port %s' % server_address)
sock.connect(server_address)

root = Tk()
# textDisplay  
textDisplay = Pmw.ScrolledText(root)  
textDisplay.pack(expand=1, padx=5, pady=5,side = LEFT)  
# textInput
textInput = Pmw.ScrolledText(root)  
textInput.pack(expand=1, padx=5, pady=5,side = LEFT)
# Send Button and its callback  
def sendMsg(event):
    message = socket.gethostname()+':'+ textInput.get()
    #print (sys.stderr, 'sending "%s"' % message)
    print(message)
    sock.sendall(message.encode())
    textInput.clear()
    #data = sock.recv(100)
    #textDisplay.insert(END, data)
    #print (sys.stderr, 'received "%s"' % data)

sendBtn = Button(root, text="Send")  
sendBtn.bind('<Button-1>', sendMsg)  
sendBtn.pack(side = LEFT)

def receiveMsg():
    while True:
        data = sock.recv(100)
        print (sys.stderr, 'client received "%s"' % data)
        textDisplay.insert(END, data)


receiveThread = threading.Thread(name='waitForMSG', target=receiveMsg)
receiveThread.start()

root.mainloop()
 

服务器端代码：

# Filename: socketServer.py

import socket
import sys

# Create a TCP/IP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# Bind the socket to the port
server_address = ('localhost', 10000)
print (sys.stderr, 'starting up on %s port %s' % server_address)
sock.bind(server_address)

# Listen for incoming connections
sock.listen(1)

while True:
    # Wait for a connection
    print (sys.stderr, 'waiting for a connection')
    connection, client_address = sock.accept()

    try:
        print (sys.stderr, 'connection from', client_address)

        # Receive the data in small chunks and retransmit it
        while True:
            data = connection.recv(16)
            print (sys.stderr, 'received "%s"' % data)
            if data:
                print (sys.stderr, 'sending data back to the client')
                connection.sendall(data)
            else:
                print (sys.stderr, 'no data from', client_address)
                break
    finally:
        # Clean up the connection
        connection.close()

客户端在监听服务器的消息采用了多线程的方法。
