windows如何搭建tcp服务器

import socket

def start_server(host='0.0.0.0', port=12345):
    # 创建socket对象
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    
    # 绑定IP和端口
    server_socket.bind((host, port))
    
    # 开始监听，最大连接数为5
    server_socket.listen(5)
    
    print(f"Server listening on {host}:{port}")
    
    while True:
        # 接受客户端连接
        client_socket, addr = server_socket.accept()
        print(f"Connection from {addr} has been established.")
        
        # 接收数据
        data = client_socket.recv(1024).decode('utf-8')
        if not data:
            break
        
        print(f"Received data: {data}")
        
        # 发送响应
        response = f"Echo: {data}"
        client_socket.send(response.encode('utf-8'))
        
        # 关闭连接
        client_socket.close()

if __name__ == "__main__":
    start_server()
