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()
