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

Python可以实现基于TCP和UDP协议的IPv4及IPv6模式，功能包含客户端发包和服务端收包。UDP通信不需要进行连接验证。先运行客户端代码，再运行服务端代码。

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

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

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:
