作爲一個練習，我尋找一個簡單的Python聊天客戶端 - 服務器系統來修改和玩弄。我在系統中發現的第一個主要失敗是它使用單個tcp連接讓服務器和客戶端進行通信。第二個是你只能有兩個人（一個使用客戶端，另一個使用服務器）進行通信。第三，連續的職位是不可能的。一個人發了一條消息，然後不得不等待另一個人在再次交談之前發送一條消息。非常，非常有限。Python聊天客戶端 - 服務器修改出錯可怕
所以我開始穿線它並試驗插座。客戶端連接到服務器一次，給他們的IP地址，創建一個監聽線程，然後重新連接到服務器的消息接收器。 所有帖子都發送到該接收者，它遍歷連接的客戶端列表，並連接到他們每個人併發送消息（發件人的名字在開頭;雜項功能）。 （我知道這樣經常打開一個新的連接效率很低，但我想保持TCP連接，直到我有它的工作，然後去UDP）
然而，奇怪的廢話開始發生。只要說我有錯誤91的惡夢。
任何人都可以識別如何呈現此代碼可在此結構和功能集內操作嗎？ （Python版本2.6 yey;忽略了無限循環，這只是一個佔位符）
服務器代碼：
from socket import *
from time import time, ctime
import Queue, threading
IP = ''
PORT = 5000
PORTPlus = 2
PORTRec = 1000
ADS = (IP, PORT)
namelist = []
clientlist = []
class clientRec(threading.Thread):
def __init__(self):
threading.Thread.__init__(self)
print "I'm this far:", (IP, (PORT + PORTRec))
self.receiver = socket(AF_INET, SOCK_STREAM)
self.receiver.bind((IP, PORT + PORTRec))
self.sender = socket(AF_INET, SOCK_STREAM)
def run(self):
global clientlist, namelist
self.receiver.listen(10)
connected = True
while connected:
tcpcli, addr = receiver.accept()
message = tcpcli.recv(1024) # Accept clien't IP for home-dialing
for i in range(clientlist.__len__()): # For each connected client
try:
sender.connect(clientlist(i)) # connect
sender.send(namelist[i] + message) # and deliver message with sender's name
sender.close()
except:
del clientlist[i], namelist[i]
print "ADS:", (IP, 5000)
handle = clientRec()
tcpsoc = socket(AF_INET, SOCK_STREAM) # Paperwork
tcpsoc.bind(ADS) # Bind self to port
tcpsoc.listen(5) # Listen on that port0
handle.start() # Start thread
# Main
while 1:
print "Waiting for connection"
tcpcli, addr = tcpsoc.accept() # Accept unknown client
print "Connection received; handling..."
namelist.append(tcpcli.recv(1024)) # Accept client's name
client_IP = tcpcli.recv(1024) # Accept clien't IP for home-dialing
client_port = int(tcpcli.recv(1024))# Accept clien't listening port
port_assign = PORT + PORTRec
tcpcli.send(str(port_assign)) # Tell the client that port
tcpcli.close() # Close client connection
clientlist.append((client_IP, client_port))# Add client to send-list
print "Handled."
tcpsoc.close()
客戶端代碼：
#!/usr/bin/env python
from socket import *
import threading, cgi, os
IP = ''
PORT = 5000
PORTmy = 100
ADS = (IP, PORT)
class iListen(threading.Thread):
def __init__(self):
threading.Thread.__init__(self)
self.receiver = socket(AF_INET, SOCK_STREAM)# Paperwork
self.receiver.bind(('', PORT + PORTmy)) # Listen on that port
self.receiver.listen(5) # Listen for posts
def run(self):
while listening:
tcpcli, addr = receiver.accept() # Accept unknown client
message = tcpcli.recv(1024)
if message == "/q":
listening = False
tcpcli.close()
# Initial CONNECT
myname = raw_input("Tell me yer name partnah: ")
tcpsoc = socket(AF_INET, SOCK_STREAM)
tcpsoc.connect(ADS) # First Connect
tcpsoc.send(myname) # Declare name
tcpsoc.send(gethostbyname(gethostname()))# Give IP address
tcpsoc.send(str(PORT + PORTmy)) # Give listening port
ADS = (IP, int(tcpsoc.recv(1024))) # Get new connect details
tcpsoc.close() # Close old connection
listen = iListen() # Create listener thread
listen.start() # Start listening
# RECONNECT
print ADS
tcpsoc = socket(AF_INET, SOCK_STREAM)
tcpsoc.connect(ADS) # reconnect to new port
connected = True
# Main Chat-loop
while connected:
mes = raw_input(">>>")
tcpsoc.send(mes)
if mes == "/q":
tcpsoc.close()
connected = False
time.sleep(4)
sys.exit()
你可能會得到幸運，並有專人編寫代碼爲你在這裏，但我懷疑這一點，partnah。 StackOverflow問題需要更專注一些，看起來不像功課練習。 – msw 2010-11-21 23:11:51
UDP聊天？哈哈很好！ PS：修正了縮進... – 2010-11-21 23:14:24
，而不是說「怪異的廢話開始發生」，你可能想解釋你所看到的詳細錯誤。另外，請嘗試將其分解爲更簡單的示例，以更加明確地分析問題。這將是爲了你自己的利益，也可能使問題變得可以回答。 – 2010-11-21 23:14:48
