在解析socketserver是如工作之前,我们先看看socektserver类的继承关系图: 请求类继承关系: server类继承关系: 有了上面的继承关系图后,我们解析socketserver就轻松多了,下面,我们从代码开始,慢慢揭开socketserver面纱: import socketserver import struct, json, os class FtpServer(socketserver.BaseRequestHandler): codi...

套接字(Socket)是网络编程的基础,它提供了一种跨网络通信的端点。 3.1 创建TCP套接字 以下是一个简单的TCP服务器和客户端示例: 服务器端代码: import socket def start_server(): server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) ...
