Python socket聊天室程序

来源：互联网发布：eva新剧场版知乎编辑：程序博客网时间：2024/06/05 15:43

今天用python的socket模块实现了一个聊天室的程序

虽然功能比较简单，但是该有的基本功能还是有的

还望大家指点

服务器端程序：

import socketimport threadingsock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)sock.bind(('localhost', 5550))sock.listen(5)print('Server', socket.gethostbyname('localhost'), 'listening ...')mydict = dict()mylist = list()#把whatToSay传给除了exceptNum的所有人def tellOthers(exceptNum, whatToSay):    for c in mylist:        if c.fileno() != exceptNum :            try:                c.send(whatToSay.encode())            except:                passdef subThreadIn(myconnection, connNumber):    nickname = myconnection.recv(1024).decode()    mydict[myconnection.fileno()] = nickname    mylist.append(myconnection)    print('connection', connNumber, ' has nickname :', nickname)    tellOthers(connNumber, '【系统提示：'+mydict[connNumber]+' 进入聊天室】')    while True:        try:            recvedMsg = myconnection.recv(1024).decode()            if recvedMsg:                print(mydict[connNumber], ':', recvedMsg)                tellOthers(connNumber, mydict[connNumber]+' :'+recvedMsg)        except (OSError, ConnectionResetError):            try:                mylist.remove(myconnection)            except:                pass            print(mydict[connNumber], 'exit, ', len(mylist), ' person left')            tellOthers(connNumber, '【系统提示：'+mydict[connNumber]+' 离开聊天室】')            myconnection.close()            returnwhile True:    connection, addr = sock.accept()    print('Accept a new connection', connection.getsockname(), connection.fileno())    try:        #connection.settimeout(5)        buf = connection.recv(1024).decode()        if buf == '1':            connection.send(b'welcome to server!')            #为当前连接开辟一个新的线程            mythread = threading.Thread(target=subThreadIn, args=(connection, connection.fileno()))            mythread.setDaemon(True)            mythread.start()                    else:            connection.send(b'please go out!')            connection.close()    except :          pass

客户端程序：

import socketimport timeimport threadingsock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)sock.connect(('localhost', 5550))sock.send(b'1')print(sock.recv(1024).decode())nickName = input('input your nickname: ')sock.send(nickName.encode())def sendThreadFunc():    while True:        try:            myword = input()            sock.send(myword.encode())            #print(sock.recv(1024).decode())        except ConnectionAbortedError:            print('Server closed this connection!')        except ConnectionResetError:            print('Server is closed!')    def recvThreadFunc():    while True:        try:            otherword = sock.recv(1024)            if otherword:                print(otherword.decode())            else:                pass        except ConnectionAbortedError:            print('Server closed this connection!')        except ConnectionResetError:            print('Server is closed!')th1 = threading.Thread(target=sendThreadFunc)th2 = threading.Thread(target=recvThreadFunc)threads = [th1, th2]for t in threads :    t.setDaemon(True)    t.start()t.join()
