Python编写的socket服务器和客户端

服务器端：
#!/usr/bin/python
import socket
host='127.0.0.1'
port=8123
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.bind((host,port))
s.listen(2)
try:

while True:
conn,add=s.accept()
while True:
data2=''
data1=conn.recv(3)
if data1=='EOF':
conn.send('hello clietn1')
break
if data1=='FOE':
conn.send('hello client2')
break
data2+=data1
print data2
except KeyboardInterrupt:
print "you have CTRL+C,Now quit"
s.close()
注：服务器端一次只接收3个字节的数据，我让读取进入循环，然后不断累加到data2中，当读取到EOF时，退出打印data2，当读取FOE时，退出打印data2，（EOF和FOE是客户端发送完数据时发送的结束符），当接收到CTRLC+C时，关闭socket

客户端1：
#!/usr/bin/env python
import socket
import os
ss=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
ss.connect(('127.0.0.1',8123))
#f=open('aa','wb')
ss.sendall('hello serverdddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd')
os.system('sleep 1')
ss.send('EOF')
data=ss.recv(1024)
print "server dafu %s"%data
ss.close()

客户端2：
#!/usr/bin/env python
import socket
import os
ss=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
ss.connect(('127.0.0.1',8123))
#f=open('aa','wb')
ss.sendall('wokao sile')
os.system('sleep 1')
ss.send('FOE')
data=ss.recv(1024)
print "server dafu %s"%data
ss.close()
