python实现的socket(tcp和udp)

from socket import * from time import ctime bufferSize=1024 def recvMsg(host,port): address=(host,port) serverSocket=socket(AF_INET,SOCK_STREAM) serverSocket.bind(address) serverSocket.listen(5) while True: print 'waiting for connection...' clientSocket,address=serverSocket.accept() print 'connected from ',address while True: data=clientSocket.recv(bufferSize) if not data:break print 'received data: ',data clientSocket.send('[%s] %s' % (ctime(),data)) clientSocket.close() serverSocket.close() recvMsg('localhost',12340)
