Python3-socketserver Module-network server framework

The Socketserver module in Python3 simplifies the task of writing Web servers

In the actual development, especially in the case of multiple concurrency, the socket module is obviously of little use to us, because if you are going through the socket module to implement the concurrent socket communication, it is too troublesome, the Socketserver module is python to provide you with a ready-made interface, You only need to write a small amount of code, you can achieve your needs

　　First, you must BaseRequestHandler create a request handler class by subclasses the class and overriding its methods, which handle() will handle incoming requests. Second, you must instantiate a server class that passes it to the server's address and request handler class. the server object's or method is then invoked handle_request() serve_forever() to process one or more requests. Finally, call server_close() close socket
