Python乙個簡單的通訊程式 客戶端 伺服器

功能是從客戶端向服務傳送乙個字串, 伺服器收到後將字串重新傳送給客戶端,同時,在連線建立之後,伺服器可以向客戶端傳送任意多的字串

客戶端:

10.248.27.23是我電腦的ip

import socket, sys

host = '10.248.27.23'
# host = raw_input("plz imput destination ip:")
# data = raw_input("plz imput what you want to submit:")
port = 51423
s = socket.socket(socket.af_inet,socket.sock_stream)
try:
s.connect((host, port))
except socket.gaierror, e:
print "address-related error connecting to server: %s" %e
sys.exit(1)
except socket.error, e:
print "connection error: %s" %e
sys.exit(1)
data = raw_input("plz imput what you want to submit:")
s.send(data)
s.shutdown(1)
print "submit complete"
while 1:
buf = s.recv(1024)
sys.stdout.write(buf)

import socket, traceback

host = ''
port = 51423
s = socket.socket(socket.af_inet, socket.sock_stream)
s.setsockopt(socket.sol_socket, socket.so_reuseaddr, 1)
s.bind((host, port))
s.listen(1)
print "done"
while 1:
try:
clientsock, clientaddr = s.accept()
except keyboardinterrupt:
raise
except:
traceback.print_exc()
continue
#get informaion form client and reply
try:
print "get connect from ", clientsock.getpeername()
data = clientsock.recv(1024)
print "the information we get is %s" % str(data)
clientsock.sendall("i`ve got the information: ")
clientsock.sendall(data)
while 1:
str = raw_input("what you want to say:")
clientsock.sendall(str)
clientsock.sendall('\n')
except (keyboardinterrupt ,systemerror):
raise
except:
traceback.print_exc()
#clocs socket
try:
clientsock.close()
except keyboardinterrupt:
raise
except:
traceback.print_exc()
