Python实现基于TCP UDP协议的IPv4 IPv6模式客户端和服务端功能示例

本文实例讲述了Python实现基于TCP UDP协议的IPv4 IPv6模式客户端和服务端功能。分享给大家供大家参考，具体如下：

由于目前工作的需要，需要在IPv4和IPv6两种网络模式下TCP和UDP的连接，要做到客户端发包，服务端收包。

前几天写了代码，但是把UDP的客户端和服务端使用TCP模式的代码了。今天在公司使用该工具的时候，发现了问题，忘记了UDP不需要验证。疏忽，疏忽。不过刚刚接触编程，可以原谅。

现在在家，已经把代码改好了。经测试可以使用。

先运行客户端：

python MiniClient.py host port mode(t4, t6, u4, u6)

再运行服务端：

python MiniServer.py host port mode(t4, t6, u4, u6)

客户端代码如下：

import socket, sys
import time
class MiniClient:
 h = ''
 p = ''
 m = ''
 def __init__(self, host, port, mode):
   self.h = host
   self.p = int(port)
   self.m = mode
 def tcpC4(self):
   tcpT4Client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
   print "Done........"
   tcpT4Client.connect((self.h, self.p))
   print "TCP IPv4 TCP mode connecting..."
   while True:
     time.sleep(1)
     tcpT4Client.send('hello')
     print "hello send to Server"
 def udpC4(self):
   udpT4Client = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
   print "UDP TCP IPv4 Mode connecting..."
   while True:
     time.sleep(1)
     udpT4Client.sendto("hello", (self.h, self.p))
     print "Hello Send to " , self.h , ' Use ', self.p, 'Port'
 def tcpC6(self):
   tcpT4Client = socket.socket(socket.AF_INET6, socket.SOCK_STREAM)
   print "Done........"
   tcpT4Client.connect((self.h, self.p))
   print "TCP IPv6 TCP mode connecting..."
   while True:
     time.sleep(1)
     tcpT4Client.send('hello')
     print "hello send to Server"
 def udpC6(self):
   udpU6Client = socket.socket(socket.AF_INET6, socket.SOCK_DGRAM)
   print "UDP TCP IPv4 Mode connecting..."
   while True:
     time.sleep(1)
     udpU6Client.sendto("hello", (self.h, self.p))
     print "Hello Send to " , self.h , ' Use ', self.p, 'Port'
if __name__ == "__main__":
 x = MiniClient(sys.argv[1], sys.argv[2], sys.argv[3])
 if x.m == 't4':
   x.tcpC4()
 elif x.m == 't6':
   x.tcpC6()
 elif x.m == 'u4':
   x.udpC4()
 else:
   x.udpC6()

服务端代码：

import socket, sys
class MiniServer:
 h = ''
 p = ''
 m = ''
 def __init__(self, host, port, mode):
   self.h = host
   self.p = int(port)
   self.m = mode
 def serverT4(self):
   tcpT4Server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
   print "Server Socket Created......."
   tcpT4Server.bind((self.h, self.p))
   print "Wating for connecting......."
   tcpT4Server.listen(5)
   while True:
     clientSock, clientaddr = tcpT4Server.accept()
     print "Connected from: ", clientSock.getpeername()
     clientSock.send('Congratulations........')
     while True:
       buf = clientSock.recv(1024)
       print buf
     #clientSock.close()
 def udpT4(self):
   udpT4Server = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
   print "UDP TCP IPv4 Mode Start....."
   udpT4Server.bind((self.h, self.p))
   print "UDP Server Start"
   while True:
     udpT4Data, udpT4ServerInfo = udpT4Server.recvfrom(1024)
     print "Receive from ", udpT4ServerInfo, " and The Data send from The Client is :", udpT4Data
 def serverT6(self):
   tcpT6Server = socket.socket(socket.AF_INET6, socket.SOCK_STREAM)
   print "Server Socket Created......."
   tcpT6Server.bind((self.h, self.p))
   print "Wating for connecting......."
   tcpT6Server.listen(5)
   while True:
     clientSock, clientaddr = tcpT6Server.accept()
     print "Connected from: ", clientSock.getpeername()
     clientSock.send('Congratulations........')
     #clientSock.close()
 def udpT6(self):
   udpT6Server = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
   print "UDP TCP IPv4 Mode Start....."
   udpT6Server.bind((self.h, self.p))
   print "UDP Server Start"
   while True:
     udpT4Data, udpT6ServerInfo = udpT6Server.recvfrom(1024)
     print "Receive from ", udpT6ServerInfo, " and The Data send from The Client is :", udpT4Data
if __name__ == "__main__":
 x = MiniServer(sys.argv[1], sys.argv[2], sys.argv[3])
 if x.m == 't4':
   x.serverT4()
 elif x.m == 't6':
   x.serverT6()
 elif x.m == 'u4':
   x.udpT4()
 else:
   x.udpT6()

希望本文所述对大家Python程序设计有所帮助。
