Python一个简单的通信程序(客户端 服务器)
功能是从客户端向服务发送一个字符串, 服务器收到后将字符串重新发送给客户端,同时,在连接建立之后,服务器可以向客户端发送任意多的字符串
客户端:
10.248.27.23是我电脑的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)
服务器:
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:
#when connect error happen, skip the error
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()
