pythonTCP UDP IPv4 IPv6 客户端和服务端的实现

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

    x = MiniServer(sys.argv[1], sys.argv[2], sys.argv[3])
