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消息,但一次只能一個用戶發送。
?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送消息。
全雙工明顯要用到多線程。我們在主線程之外創建兩個子線程,一個負責接收消息,另一個負責接受用戶輸入并發送消息。
