Python socketserver Framework Programming

1. Socketserver Framework

In Python, Socketserver is an integrated module that has the following features:
　　

• You can create TCP and UDP servers by using the Socketserver framework.
• In the background for you to do a good job of every basic step.
• You can manually create a server to spoof the client and analyze its behavior.

2. Use of the Socketserver module

• Must be a subclass of Baserequesthandler
• overriding the handle () function
• Call handle_request or Serve_forever to handle the client program.
• For the TCP server,
  
  • Self.request is the client socket
  • Self.client_address is the client's detailed address

3. Python Code

Service side:

#!/usr/bin/env python# _*_ Coding=utf-8 _*_ImportSocketserver class sockhandler(socketserver.baserequesthandler):     def handle(self):        Print "received a connection to the client:", self.client_address data =' Start '         whileLen (data): data = SELF.REQUEST.RECV (2048) Self.request.send ("return:"+ data)Print "Client off ..."SERADDR = ("0.0.0.0",8888)Print "Waiting for connection ..."Server = Socketserver.tcpserver (seraddr,sockhandler) server.serve_forever ()

The client tests with the NC command:

$ nc 192.168.1.95 8888
