Server：
- # server
- import socket
- address = ('127.0.0.1', 31500)
- s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # s = socket.socket()
- s.bind(address)
- s.listen(5)
- ss, addr = s.accept()
- print 'got connected from',addr
- ss.send('byebye')
- ra = ss.recv(512)
- print ra
- ss.close()
- s.close()
Client：
- # client
- import socket
- address = ('127.0.0.1', 31500)
- s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
- s.connect(address)
- data = s.recv(512)
- print 'the data received is',data
- s.send('hihi')
- s.close()
运行结果：
server
[work@db-testing-com06-vm3.db01.baidu.com python]$ python server.py
got connected from ('127.0.0.1', 47872)
hihi
client
[work@db-testing-com06-vm3.db01.baidu.com python]$ python client.py
the data received is byebye

一个简单的服务器和客户端通信的例子
服务器：
s=socket.socket()
s.bind(('xxx.xxx.xxx.xxx',xxxx)) #ip地址和端口号
s.listen(5)
cs,address = s.accept()
print 'got connected from',address
cs.send('byebye')
ra=cs.recv(512)
print ra
cs.close()
客户端：
s=socket.socket()
s.connect(('xxx.xxx.xxx.xxx',xxxx)) #与服务器程序ip地址和端口号相同
data=s.recv(512)
s.send('hihi')
s.close()
print 'the data received is',data
运行：
在本机测试（windows环境下，可以将ip地址改为本机ip，端口号在1024以上，windows将1024以下的为保留），运行--CMD--进入命令行模式
先python 服务器程序，后python 客户端程序即可。
或者启动服务器程序后，用telnet ip地址 端口号，也可以得到同样结果。
让server持续接受连接
server.py
s=socket.socket()
s.bind(('192.168.43.137',2000))
s.listen(5)
while 1:
cs,address = s.accept()
print 'got connected from',address
cs.send('hello I am server,welcome')
ra=cs.recv(512)
print ra
cs.close()
测试两个一个程序中两个socket并存是否可行
client.py
s=socket.socket()
s.connect(('192.168.43.137',2000))
data=s.recv(512)
print 'the data received is/n ',data
s.send('hihi I am client')
sock2 = socket.socket()
sock2.connect(('192.168.43.137',2000))
data2=sock2.recv(512)
print 'the data received from server is/n ',data2
sock2.send('client send use sock2')
sock2.close()
s.close()
