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()
