如何在局域网中使用聊天脚本

Question

我想在家里的网络上使用我的聊天程序。我在本地主机上成功运行的代码。我想与我的家庭网络上的系统进行通信，并运行客户端脚本。如果要在本地主机上运行，则将服务器声明为'localhost'。

• 我需要使用什么地址才能在LAN上使用它?
• 我的程序结构需要如何改变以适应任务?

服务器代码如下:

import select
import socket
import sys
import argparse
class ChatServer():
def __init__(self, host, port):
    self.host = host
    self.port = port
    self.clients = [] #Keep a tab of all the connected clients
    #Initialise the server socket
    self.server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    self.server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR,1)
    self.server.bind((self.host, self.port))
    self.server.listen(BACKLOG)
    print "Server listening on port %s" %self.port
    self.inputs = [self.server, sys.stdin] #Keeps a tab of all the incoming connections
    self.outputs = [] #Keep a tab of all the sockets to which we need to send data
def run(self):
    running =  True
    while running:
        try:
            readable, writable, exceptional = select.select(self.inputs, self.outputs, self.outputs)
        except socket.error, e:
            break
        for sock in readable:
            if sock == self.server:
                #If the readable socket is server then we need to accept connections and receive messages and broadcast them
                client, address = sock.accept() #client contains the socket information and address contains the address information of the client
                print 'Chat server got connected to client %s:%s ' %(address[0],address[1])
                self.clients.append((client, address))
                self.inputs.append(client)
                msg = 'Connected new client %d at %s:%s '%(len(self.clients),address[0],address[1])
                for s in self.outputs:
                    s.sendall(msg)
                self.outputs.append(client)
            elif sock == sys.stdin:
                junk = sys.stdin.readline()
                running =  False
            else:
                #All the clients that have been connected to the server
                try:
                    data = sock.recv(4096)
                    if data:
                        msg = 'Client %s:%s says : %s ' %(address[0],address[1],data)
                        for s in self.outputs:
                            s.sendall(msg)
                except socket.error , e:
                    self.inputs.remove(sock)
                    self.outputs.remove(sock)
    self.server.close()

客户端代码如下:

class ChatClient():
def __init__(self,name,port, host = SERVER_HOST):
    self.name = name
    self.host = host
    self.port = port
    self.connected = False
    try:
        self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.sock.connect((self.host, self.port))
        print 'Client connected to Server at port : %s' %self.port
        self.connected = True
    except socket.error,e:
        print 'Failed to connect to socket server @port: %s' %self.port
def run(self):
    while self.connected:
        readable, writable, exceptional = select.select([0,self.sock],[],[])
        for sock in readable:
            if sock == 0:
                data = sys.stdin.readline()
                if data:
                    self.sock.sendall(data)
            elif sock == self.sock:
                data = self.sock.recv(4096)
                if data:
                    sys.stdout.write(data + 'n')
                    sys.stdout.flush()
                else:
                    print 'Shutting Down'
                    self.connected = False
                    break

启动Server和Client的脚本如下:

if __name__ == '__main__':
parser = argparse.ArgumentParser(description = 'Chat Server')
parser.add_argument('--name',action = 'store', dest = 'name',required = True)
parser.add_argument('--port', action = 'store', type = int, dest = 'port',required = True)
givenArgs = parser.parse_args()
name = givenArgs.name
port = givenArgs.port
if name == 'server':
    server = ChatServer(SERVER_HOST, port)
    server.run()
else:
    client = ChatClient(name,port)
    client.run()

Answer 1

在客户端和服务器机器的命令行中执行ifconfig(在Unix和Mac OS上)或ipconfig(在Windows上)。然后尝试了解列出的接口中哪个是您的局域网。我的建议是，这样的接口最有可能将在192.168.x.x网络。然后在客户端和服务器脚本中使用这两个地址。
