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()
