Python socket聊天室程序

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 socket
import threading

sock = 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:
                pass

def 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()
            return

while 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 socket
import time
import threading

sock = 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()
