Question

我正在尝试向特定客户发送消息。我已经制作了一个向所有客户端发送消息的服务器，但我不知道如何向特定客户端发送消息。，这是我的服务器代码：

server.py

from socket import *
from codecs import decode
#from chatrecord import ChatRecord
from threading import Thread
from time import ctime

class ClientHandler(Thread):

    def __init__(self,client,address):
        global sockets
        global addresses
        Thread.__init__(self)
        self._client = client
        self._address = address
        sockets.append(self._client)
        addresses.append(self._address)

    def run(self):
        self._client.send('Welcome to the chatroom!\n')

        while 1:
            message =self._client.recv(BUFSIZE)
            print '\n\n',sockets
            if not message:
                print "Client disconnected."
                addIndex=sockets.index(self._client)
                del sockets[addIndex]
                del addresses[addIndex]
                self._client.close()
                break
            else:
                if 'ONLINE#' in message:
                    for x in sockets:
                        if (x!=self._client):
                            try:
                                x.send(message[7:])
                            except:
                                print 'disconnected'
                                continue
                    print message[7:]
                else:     
                    for x in sockets:
                        try:
                            x.send(message)
                            /*sockets is the list of all client*/
                        except:
                            print ' '
                            continue
                    print message


HOST = 'localhost'
PORT = 1235
ADDRESS = (HOST,PORT)
BUFSIZE = 1024
server = socket(AF_INET,SOCK_STREAM)
server.bind(ADDRESS)
server.listen(5)
sockets=[]
addresses=[]

while True:
    print "Waiting for connection..."
    client, address = server.accept()
    print('...client connected from: ',address)
    handler = ClientHandler(client,address)
    handler.start()

由于这是一个聊天室，我会在连接时为客户创建一个带有昵称的字典。

客户端会收到提示 - ＆gt;选一个名字！

客户选择：clientname = jimbob

mydict = {}
mydict[clientname] = self._address

然后，您只需通过昵称

获取用户

for client,addr in mydict.iteritems():
   if client == "jimbob":
       destinationaddr = addr
       break

自从我完成python以来已经有一段时间了，所以你可能想把它当作更多的伪代码。

您可能还想查找SocketServer

的文档

编辑：您还需要查看客户端连接时是否采用该昵称。它将与上面的for循环非常相似，除非用户存在，否则可以设置一个布尔值。
