使用socket实现简单聊天室

通过socket实现简单的聊天室

1、服务端代码:serverselect.py

#!/usr/bin/env python 
#coding:utf8
import  socket

import select


class SelectServer(object):
    def __init__(self,host,port,backlog):
        self.host = host
        self.prot = port
        self.address = (host,port)
        self.backlog = backlog
        socket.server = None
        self.socketList = list()

    def _initSocket(self):
        self.server = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
        self.server.bind(self.address)
        self.server.listen(self.backlog)
        self.socketList.append(self.server)
        print("chat room has start")
        while 1 :
            rlist,wlist ,elist = select.select(self.socketList,[],[])
            for r in rlist:
                if r == self.server:
                    ServrtConn,clientAddr = self.server.accept()
                    self.socketList.append(ServrtConn)
                    print("{0}进入房间".format(clientAddr))
                    self.broadcast(r,"{0}进入房间".format(clientAddr))
                else:
                    try:
                        data = r.recv(2048)
                        if data:
                            self.broadcast(r, "{0}:{1}".format(clientAddr, ServrtConn))
                            print("{0} say:{1}".format(clientAddr,data))
                    except Exception as e:
                        self.broadcast(r, "{0}  下线".format(clientAddr))
                        print("{0}下线".format(clientAddr))
                        r.close()
                        self.socketList.remove(r)

    def broadcast(self,r,data):
        for i in self.socketList:
            if i != r  and i != self.server:
                try:
                    i.sendall(data)
                except Exception as e :
                    i.close()
                    self.socketList.remove(i)
def main():
    selectServer = SelectServer(host="192.168.88.100",port=4321,backlog=5)
    selectServer._initSocket()
if __name__ == "__main__":
    main()

　　2、客户端代码：clientselect.py

#!/usr/bin/env python 
#coding:utf8

import  socket,select,string,sys
import  time

if __name__ == "__main__":
    host = "192.168.88.100"
    port = 4321
    s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    s.settimeout(2)
    try:
        s.connect((host,port))
    except :
        print("Unable to connect")
        sys.exit()
    print('Connected to remote host. Start sending messages')

    while 1 :
        rlist = [sys.stdin,s]
        read_list, write_list, error_list = select.select(rlist, [], [])
        for sock in read_list:
            if sock == s :
                data = sock.recv(2048)
                if not data :
                    continue
                else:
                    sys.stdout.write(data)
            else:
                msg = raw_input("i say:")
                # print(msg)
                s.sendall(msg)
