如何在局域网上使用聊天脚本？

Question

我想在我的家庭网络上使用我的聊天程序。我已经在我的本地主机上成功运行了代码。 我想与家庭网络上的系统进行通信并运行客户端脚本。 为了在localhost上运行它，服务器被声明为'localhost'。

• 我需要在局域网上使用什么地址？
• 我的程序结构如何改变以适应任务？

服务器的代码如下：

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() 

的代码，客户端如下：

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 

发起的服务器和客户端是如下脚本：

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()

做ifconfig（在Unix和Mac OS上）或ipconfig（在Windows上）在客户端和服务器上的命令行中。然后尝试了解哪些列出的接口是您的LAN。我的建议是，这样的接口很可能会在192.168.x.x网络中。之后，相应地在您的客户端和服务器脚本中使用这两个地址。
