我正在用 Python 编写一个多人游戏服务器和客户端，使用内置的 SocketServer 的 TCPServer 和 ThreadingMixIn，因为它似乎比手动管理套接字和线程模块更容易。（为此，我想坚持使用内置模块。）它使用类似于 HTTP 通信 (GTP) 的协议。
仅涉及一个客户端的请求已经生效。如果客户端发送请求“ ”，服务器只需向该客户端GET /index.html GTP/0.2响应“ ”。GTP/0.2 200 OK但是如果客户端 A 和 B 之间正在进行游戏（如服务器状态中记录的那样）并且客户端 A 发送请求“ TURN <my turn info> GTP/0.2”，那么在轮到玩家 A 之后，服务器如何通知玩家 A和B 更改？
到目前为止，这是我的代码的要点：
import SocketServer
import socket, threading # not yet used

def __init__(self, server_address, RequestHandlerClass):
SocketServer.TCPServer.__init__(self, server_address, RequestHandlerClass)

self.request_data = self.request.recv(4096)
if not self.request_data:
break # Client disconnected
# delegate handling to do_GET, do_POST, etc
do_method = 'do_' + self.request_data.split()[0]
if not hasattr(self, do_method):
self.request.sendall("GTP/0.2 501 Not Implemented\r\n\r\n")
continue

def do_EXIT(self):

server.serve_forever()
