小小聊天室Python代码实现_Python

相对于Java方式的聊天室，Python同样可以做得到。而且可以做的更加的优雅。想必少了那么多的各种流的Python Socket，你一定会喜欢的。
至于知识点相关的内容，这里就不多说了。

UDP方式

服务器端

									# coding:utf-8

									# __author__ = 'Mark sinoberg'

									# __date__ = '2016/7/7'

									# __Desc__ = 创建一个简单的套接字监听请求

									import socket

									HOST = '192.168.59.255'

									PORT = 9998

									s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)

									s.bind(('',PORT))

									print '套接字已启动！'

									while True:

									 data,addr = s.recvfrom(1024)

									 print addr,str(' : ')+data

客户端

									# coding:utf-8

									# __author__ = 'Mark sinoberg'

									# __date__ = '2016/7/7'

									# __Desc__ = socket的客户端的简单实现

									import socket

									PORT = 9998

									HOST = '192.168.59.255'

									s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)

									words = raw_input('Client:')

									while words != 'quit':

									 s.sendto(words,(HOST,PORT))

									 words = raw_input('Client:')

									s.close()

是不是很简单啊。我们需要注意的就是socket的第二个参数为SOCK_DGRAM。因为这和TCP方式的SOCK_STREAM 有所不同。

TCP方式

服务器端

									# coding:utf-8

									# __author__ = 'Mark sinoberg'

									# __date__ = '2016/7/7'

									# __Desc__ = 简单的tcpsocket的实现

									from socket import *

									from time import ctime

									HOST = ''

									PORT = 9999

									BUFFERSIZE = 1024

									ADDRESS = (HOST,PORT)

									s = socket(AF_INET,SOCK_STREAM)

									s.bind(ADDRESS)

									s.listen(5)

									while True:

									 print 'Waiting for clients cennect!'

									 tcpclient,addr = s.accept()

									 print 'Connected By ',addr

									 while True:

									  try:

									   data = tcpclient.recv(BUFFERSIZE)

									  except Exception,e:

									   print e.message

									   tcpclient.close()

									   break

									  if not data:

									   print "No Data received!"

									   break

									  senddata = 'Hi,you send me:[%s]%s'%(ctime(),data.encode('utf8'))

									  tcpclient.send(senddata.encode('utf8'))

									  print addr,' Says:',ctime(),data.encode('utf8')

									tcpclient.close()

									s.close()

客户端

									# coding:utf-8

									# __author__ = 'Mark sinoberg'

									# __date__ = '2016/7/7'

									# __Desc__ = 简单的tcp socket客户端的实现

									from socket import *

									class TcpClient:

									 # HOST = 'localhost'

									 PORT = 9999

									 HOST = '192.168.59.225'

									 BUFFSIZ = 1024

									 ADDR = (HOST,PORT)

									 def __init__(self):

									  self.client = socket(AF_INET,SOCK_STREAM)

									  self.client.connect((self.HOST,self.PORT))

									  while True:

									   senddata = raw_input('>>>')

									   if not senddata:

									    print 'Please input some words!\n>>>'

									    continue

									   if senddata == "quit":

									    break

									   self.client.send(senddata.encode('utf8'))

									   recvdata = self.client.recv(self.BUFFSIZ)

									   if not recvdata:

									    break

									   print recvdata.encode('utf8')

									if __name__ == "__main__":

									 client = TcpClient()

TCP方式演示结果：(注意先开启服务器端)

服务器端

D:\Software\Python2\python.exe E:/Code/Python/MyTestSet/sockettest/SimpleTCPServer.py
Waiting for clients cennect!
Connected By ('192.168.59.225', 63095)
('192.168.59.225', 63095) Says: Thu Jul 07 16:01:10 2016 Hello World
('192.168.59.225', 63095) Says: Thu Jul 07 16:01:15 2016 haode
No Data received!
Waiting for clients cennect!

客户端

D:\Software\Python2\python.exe E:/Code/Python/MyTestSet/sockettest/SimpleTcpClient.py
>>>Hello World
Hi,you send me:[Thu Jul 07 16:01:10 2016]Hello World
>>>
Please input some words!
>>>
>>>haode
Hi,you send me:[Thu Jul 07 16:01:15 2016]haode
>>>quit

Process finished with exit code 0

总结

简单的使用TCP或者是UDP确实很容易，然而要想更好的利用这两个协议，就需要好好的设计一番了。

这里我想强调的是，注意tcp和udp创建套接字时指定的参数即可。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持服务器之家。
