基於Python的TCP阻塞式echo伺服器

標籤：

上述問題的出現是因為沒有設定listen函數

from socket import *from time import ctimeHOST = ‘‘PORT = 21567BUFSIZ = 1024ADDR = (HOST,PORT)tcpSerSock = socket(AF_INET,SOCK_STREAM) tcpSerSock.bind(ADDR)tcpSerSock.listen(5)while True:print ‘waiting for connection...‘tcpCliSock, addr = tcpSerSock.accept()print ‘connected from:‘,addrwhile True:data = tcpCliSock.recv(BUFSIZ)if not data:breakprint ‘recv data : ‘,datatcpCliSock.send(‘[%s] %s‘ % (ctime(),data))tcpCliSock.close()tcpSerSock.close()
