Python基于tcp和udp两种方式实现socket

1、基于socket.sock_stream实现tcp连接

sock_stream 是有保障的(即能保证数据正确传送到对方)面向连接的SOCKET，多用于资料(如文件)传送。
SOCK_STREAM是基于TCP的，数据传输比较有保障。基于广播SOCK_STREAM 是数据流,一般是tcp/ip协议的编程,

tcp服务端

#!/usr/bin/env python
# -*- coding:utf8 -*-
 
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
 
import socket
 
class TcpServer(object):
    def tcpServer(self):
        #socket.SOCK_STREAM表示启动tcp协议的socket传输
        sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        # 绑定同一个域名下的所有机器
        sock.bind(('', 10086))
        sock.listen(5)
        
        while True:
            clientSock, (remote_address, remote_port) = sock.accept()
            # 接收客户端的ip, port
            print("[%s:%s] connect" % (remote_address, remote_port))     
            
            recvData = clientSock.recv(1024)
            sendDataLen = clientSock.send("this is response data from server")
            print("recvData : %s" % (recvData))
            print("sendDataLen: %d " % (sendDataLen))
            clientSock.close()
            
if __name__ == "__main__":
    tcpServer = TcpServer()
    tcpServer.tcpServer()

tcp客户端

#!/usr/bin/env python
# -*- coding:utf8 -*-
 
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
 
import socket
 
class TcpClient(object):
    def tcpclient(self):
        clientSock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        clientSock.connect(('127.0.0.1', 9527))
 
        sendDataLen = clientSock.send("this is send data from client")
        recvData = clientSock.recv(1024)
        print("recvData : %s" % (recvData))
        print("sendDataLen: %d " % (sendDataLen))
        
        clientSock.close()
        
if __name__ == "__main__":
    tcpClient = TcpClient()
    tcpClient .tcpclient()

2、基于socket.sock_dgram实现udp连接

sock_dgram 是无保障的面向消息的socket ， 主要用于在网络上发广播信息。
SOCK_DGRAM是基于UDP的，专门用于局域网，SOCK_DGRAM分是数据抱,是udp协议网络编程

udp服务端

#!/usr/bin/env python
# -*- coding:utf8 -*-
 
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
 
import socket
 
class UdpServer(object):
    def udpServer(self):
        #socket.SOCK_DGRAM表示启动udp协议的socket传输
        sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        # 绑定同一个域名下的所有机器
        sock.bind(('', 10086))       
        
        while True:
            recvData, (remote_address, remote_port) = sock.recvfrom(1024)
            # 接收客户端的ip, port
            print("[%s:%s] connect" % (remote_address, remote_port))     
            
            sendDataLen = sock.sendto("this is send  data from server", (remote_address, remote_port))
            print("recvData : %s" % (recvData))
            print("sendDataLen: %d " % (sendDataLen))
            
        sock.close()
            
if __name__ == "__main__":
    udpServer = UdpServer()
    udpServer.udpServer()

udp客户端

#!/usr/bin/env python
# -*- coding:utf8 -*-
 
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
 
import socket
 
class UdpClient(object):
    def udpclient(self):
        clientSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
 
        sendDataLen = clientSock.sendto("this is send data from client", ('localhost', 10086))
        recvData = clientSock.recvfrom(1024)
        print("recvData : %s" % (recvData))
        print("sendDataLen: %d " % (sendDataLen))
        
        clientSock.close()
        
if __name__ == "__main__":
    udpClient = UdpClient()
    udpClient.udpclient()
