SocketServer与客户端进行连接的示意图：
只要客户端连接进来，我们就为客户端创建1个线程或进程，创建完成之后，客户端直接和创建的线程直接进行通信（即3和4步），因此这样的话可以通过这个模块传输大的文件。
1.基于线程版本的SocketServer示例
server.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
import SocketServer
class MyServer(SocketServer.BaseRequestHandler):
#重写handle方法
def handle(self):
# print self.request,self.client_address,self.server
conn = self.request
conn.sendall('welcome to call 10086，plz input 1,0 connect man servervice.')
Flag = True
while Flag:
data = conn.recv(1024)
if data == 'exit':
Flag = False
elif data == '0':
conn.sendall('you have being getting man service....')
else:
conn.sendall('plz input again.')
if __name__ == '__main__':
#创建SocketServer线程对象
server = SocketServer.ThreadingTCPServer(('127.0.0.1',8009),MyServer)
#执行server对象的serve_forever方法
server.serve_forever()
client.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
import socket
ip_port = ('127.0.0.1',8009)
sk = socket.socket()
sk.connect(ip_port)
sk.settimeout(5)
while True:
data = sk.recv(1024)
print 'receive:',data
inp = raw_input('please input:')
sk.sendall(inp)
if inp == 'exit':
break
sk.close()
2.基于进程版本的SocketServer的示例（将上述服务器端中的ThreadingTCPServer换成ForkingTCPServer即可）
server.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
import SocketServer
class MyServer(SocketServer.BaseRequestHandler):
#重写handle方法
def handle(self):
# print self.request,self.client_address,self.server
conn = self.request
conn.sendall('welcome to call 10086，plz input 1,0 connect man servervice.')
Flag = True
while Flag:
data = conn.recv(1024)
if data == 'exit':
Flag = False
elif data == '0':
conn.sendall('you have being getting man service....')
else:
conn.sendall('plz input again.')
if __name__ == '__main__':
#创建SocketServer线程对象
server = SocketServer.ForkingTCPServer(('127.0.0.1',8009),MyServer)
#执行server对象的serve_forever方法
server.serve_forever()
client.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
import socket
ip_port = ('127.0.0.1',8009)
sk = socket.socket()
sk.connect(ip_port)
sk.settimeout(5)
while True:
data = sk.recv(1024)
print 'receive:',data
inp = raw_input('please input:')
sk.sendall(inp)
if inp == 'exit':
break
sk.close()
