目标：实现客户端与服务端的socket通信，消息传输。
客户端
客户端代码：
from socket import socket,AF_INET,SOCK_STREAM #服务端的ip地址 server_ip = '127.0.0.1' #服务端socket绑定的端口号 server_port = 20000 if __name__ == '__main__': while True: str_msg = input("请输入要发送信息：") if str_msg != "": bytes_msg = bytes(str_msg, encoding = "gbk") client = socket(AF_INET,SOCK_STREAM) client.connect((server_ip,server_port)) client.send(bytes_msg) print(str(client.recv(8192),encoding="gbk")) client.close()
客户端（Mac系统）运行截图：
服务端
服务端代码：
from socketserver import BaseRequestHandler, TCPServer #指定接收消息的客户端ip列表 target_clients = ["10.235.0.109"] class EchoHandler(BaseRequestHandler): def handle(self): for target_client in target_clients: if target_client in self.client_address: print('Got connection from', self.client_address) msg = self.request.recv(8192) if not msg: break ret_msg = bytes("自动回复：消息已收到！", encoding = "gbk") self.request.send(ret_msg) print(str(msg, encoding = "gbk")) break if __name__ == '__main__': from threading import Thread NWORKERS = 16 #绑定socket服务端所在ip和端口号 serv = TCPServer(('', 20000), EchoHandler) for n in range(NWORKERS): t = Thread(target=serv.serve_forever) t.daemon = True t.start() serv.serve_forever()
服务端（Windows系统）运行截图，注意要设置cmd活动页代码为936（chcp 936）方可显示中文，设置cmd属性中的字体为点阵字体：
