代码简单，直接看代码吧:
复制代码 代码如下:
import socket
import threading
import re
#import Tkinter

def ser():
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.bind(('',33333))
s.listen(1)
conn,addr=s.accept()
while True:
print '[%s:%d] send a message to me: %s'%(addr[0],addr[1],conn.recv(1024))
s.close()

def clt():
c=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
ip_pattern=re.compile(r'^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])$')
while True:
ip=raw_input('Input the Server\'s IPv4 address:')
ip_match=ip_pattern.match(ip)
if ip_match:
break
c.connect((ip,33333))
while True:
sms=raw_input('Input the message you want to send:')
c.sendall(sms)
c.close()

if __name__=="__main__":
ser=threading.Thread(target=ser)
clt=threading.Thread(target=clt)
ser.start()
clt.start()
ser.join()
clt.join()
