這篇文章主要為大家詳細介紹了python基于C/S模式實現聊天室功能，具有一定的參考價值，感興趣的小伙伴們可以參考一下

最簡單的模式，C/S模式實現聊天室

從半雙工開始，何謂半雙工？半雙工即是說雙方可以互發(fā)消息，但一次只能一個用戶發(fā)送。

只要稍微會點socket編程的人都會覺得很簡單，所以過過場，直接上代碼。

服務器端代碼：

from socket import *
from time import ctime
 
HOST = ''
PORT = 4568
BUFSIZE = 1024
ADDR = (HOST,PORT)
 
tcpSerSocket = socket(AF_INET, SOCK_STREAM)
tcpSerSocket.bind(ADDR)
tcpSerSocket.listen(5)
 
while True:
 print('waitint for connection...')
 tcpCliSocket, addr = tcpSerSocket.accept()
 print('connecting from: ', addr)
 
 while True:
 data = tcpCliSocket.recv(BUFSIZE)
 if not data:
  break
 print data
 msg = raw_input('>')
 tcpCliSocket.send('[%s] %s' % (ctime(), msg))
 
tcpCliSocket.close()
tcpSerSocket.close()

客戶端代碼：

from socket import *
 
HOST = 'localhost'
PORT = 4568
BUFSIZE = 1024
ADDR = (HOST, PORT)
 
tcpCliSocket = socket(AF_INET, SOCK_STREAM)
tcpCliSocket.connect(ADDR)
 
while True:
 data = raw_input('>>')
 if not data:
 break
 tcpCliSocket.send(data)
 data = tcpCliSocket.recv(BUFSIZE)
 if not data:
 break
 print data
 
tcpCliSocket.close()

運行結果我就不截圖了，如果還不會的就復制下來運行一遍。

上面只是最簡單的入門，一點都不好使，問題多著。

下面看怎么實現全雙工。全雙工就是雙方可任意給對方發(fā)送消息。

全雙工明顯要用到多線程。我們在主線程之外創(chuàng)建兩個子線程，一個負責接收消息，另一個負責接受用戶輸入并發(fā)送消息。

服務器端代碼：

#coding: utf-8
from socket import *
from time import ctime
import threading
from sys import stdout
 
HOST = ''
PORT = 21567
BUFSIZE = 1024
ADDR = (HOST, PORT)
 
def Send(sck):
 while True:
 data = raw_input('>')
 sck.send(data)
 
def Deal(sck, addr):
 while True:
 data = sck.recv(BUFSIZE)
 if data == "quit":
  sck.close()
  break
 str = '\nfrom' + addr[0] + ':' + data + '\n>'
 stdout.write(str)
 
chatSerSock = socket(AF_INET, SOCK_STREAM)
chatSerSock.bind(ADDR)
chatSerSock.listen(5)
 
threads = []
 
while True:
 print 'waiting for connection...'
 chatCliSock, addr = chatSerSock.accept()
 print "...connected from: ", addr
 t = threading.Thread(target=Deal, args=(chatCliSock, addr))
 threads.append(t)
 t = threading.Thread(target=Send, args=(chatCliSock,))
 threads.append(t)
 for i in range(len(threads)):
 threads[i].start()
 threads[0].join()
 
chatCliSock.close()
chatSerSock.close()

客戶端代碼：

#coding: utf8
from socket import *
from time import ctime
import threading
from sys import stdout
 
def Send(sck, test):
 while True:
 data = raw_input('>')
 sck.send(data)
 if data == "quit":
  break
def Recieve(sck, test):
 while True:
 data = sck.recv(BUFSIZ)
 if data == "quit":
  sck.close()
  break
 str = "\nfrom server:" + data + "\n>"
 stdout.write(str)
 
HOST = 'localhost'
PORT= 21567
BUFSIZ = 1024
ADDR = (HOST, PORT)
threads = []
 
if __name__ == "__main__":
 chatCliSock = socket(AF_INET, SOCK_STREAM)
 chatCliSock.connect(ADDR)
 t = threading.Thread(target=Send, args = (chatCliSock, None))
 threads.append(t)
 t = threading.Thread(target=Recieve, args = (chatCliSock, None))
 threads.append(t)
 for i in range(len(threads)):
 threads[i].start()
 threads[0].join()
 
chatCliSock.close()
