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，因为它看起来比手动管理套接字和线程模块更容易。 （我想坚持使用内置模块。）它使用类似于 HTTP 的协议进行通信 (GTP)。
仅涉及一个客户的请求已经可以工作。如果客户端发送请求“GET /index.html GTP/0.2“，服务器只需要响应”GTP/0.2 200 OK“ 到该客户端。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”，那么轮到玩家A后，服务器如何通知both球员A和B有何变化？
到目前为止，我的代码的要点如下：
import SocketServer
import socket, threading # not yet used
class ThreadingGameServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer):
def __init__(self, server_address, RequestHandlerClass):
SocketServer.TCPServer.__init__(self, server_address, RequestHandlerClass)
self.players = []
self.games = []
class GameRequestHandler(SocketServer.BaseRequestHandler):
def setup(self):
self.request_data = None
self.response_data = None
def handle(self):
while True:
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
try:
do = getattr(self, do_method)
do()
except Exception as e:
break
def do_GET(self):
body = '<contents of {}>'.format(self.my_request.param)
data = "GTP/0.2 200 OK\r\nContent-Length: {}\r\n\r\n{}".format(len(body), body)
self.request.sendall(data)
def do_LOGIN(self):
"""

Add the player to self.server.players.
Respond with 200 OK, body "Welcome!, <username>".
"""
def do_PLAY(self):
"""

"""
def do_TURN(self):
"""

"""
def do_EXIT(self):
"""

"""
class GameClient(object):
def __init__(self, server_address):
self.socket = socket.create_connection(server_address)
def run(self):
"""

Print the reply body, e.g. "Welcome, foobar!"
"""
# On the server machine
server = ThreadingGameServer((socket.gethostname(), 4242), GameRequestHandler)
server.serve_forever()
# On each client machine
client = GameClient(('server.mygame.com', 4242))
client.run()
