I am developing (for study only) a code for a python chat, and I came across an error during the client-server communication, I would like some guidance about it, since I can not identify a solution. Here is the code and the image of the error.
Server:
import threading # threads
from socket import * # sockets
clientes_conn = [] # Lista de conexões/clientes
clientes_name = [] # Lista dos nomes das conexões
class minhaThread (threading.Thread):
def __init__(self, threadID, threadName, conn):
threading.Thread.__init__(self)
self.id = threadID
self.name = threadName
self.conn = conn
def run(self):
chat_geral(self.conn,self.name)
'''
param == 1 => Mensagem do sistema
param == 2 => Mensagem do cliente
'''
def enviar_mensagem(msg, name, param):
if param == 1:
for conn in clientes_conn:
conn.send(msg)
print msg
else:
for conn in clientes_conn:
conn.send("("+name+"): "+msg)
print "("+name+"): "+msg
def adicionar_cliente(conn, _id):
while 1:
message2 = conn.recv(1024)
if message2 == "":
continue
if message2 in clientes_name:
serverSocket.send("O nome informado está sendo usado por um cliente atualmente.\n")
continue
clientes_conn.append(conn)
clientes_name.append(message2)
success = "Cliente '"+str(message2)+"' conectado com sucesso!"
enviar_mensagem(success, message2, 1)
# Entra no terceiro while 1
thread = minhaThread(_id, message2, conn).start()
clientes_conn.remove(conn)
clientes_name.remove(message2)
conn.close()
break
def chat_geral(conn, name):
while 1:
msg = conn.recv(1024)
if msg == "Sair" or msg == "sair":
sair = "Cliente "+name+" está saindo do chat."
enviar_mensagem(sair, name, 1)
break
enviar_mensagem(msg, name, 2)
serverName = 'localhost'
serverPort = 8080
serverSocket = socket(AF_INET,SOCK_STREAM)
serverSocket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
serverSocket.bind((serverName,serverPort))
serverSocket.listen(1)
print "Servidor TCP esperando conexoes na porta %d ..." % (serverPort)
id_padrao = 0
while 1:
connectionSocket, address = serverSocket.accept()
print "Cliente "+str(address[1])+" tentando se conectar..."
adicionar_cliente(connectionSocket, id_padrao)
id_padrao += 1
serverSocket.close()
