简单socket编程2

上一节我们提到了socket编程的基本形式,这一节我们加强服务端的性能!

#!/usr/bin/env python
import socket, threading
class ClientThread(threading.Thread):
def __init__(self, ip, port, socket):
threading.Thread.__init__(self)
self.ip = ip
self.port = port
self.socket = socket
print "[+] New thread started for "+ip+":"+str(port)
def run(self):
print "Connection from : "+ip+":"+str(port)
self.socket.send("\nWelcome to the server\n\n")
data = "dummydata"
while len(data):
data = self.socket.recv(2048)
print "Client sent : "+data
self.socket.send("You sent me : "+data)
print "Client disconnected..."
host = "0.0.0.0"
port = 9999
tcpsock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
tcpsock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
tcpsock.bind((host,port))
threads = []
while True:
tcpsock.listen(4)
print "\nListening for incoming connections..."
(clientsock, (ip, port)) = tcpsock.accept()
newthread = ClientThread(ip, port, clientsock)
newthread.start()
threads.append(newthread)
for t in threads:
t.join()
