python连接池实现示例程序

复制代码 代码如下:

import socket
import Queue
import threading

def worker():
while True:
i = q.get()
conn=i[0]
addr=i[1]
while 1:
sms=conn.recv(1024)
if sms!="":
print "Message from ("+str(addr[0])+":"+str(addr[1])+"): "+sms
else:
print "Close the Connection from ("+str(addr[0])+":"+str(addr[1])+")"
conn.close()
break
q.task_done()

if name=="main":
q = Queue.Queue()
thread_num=5000

s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)  
s.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)  
s.bind(("",4242))  
s.listen(50000)  
print "Server is listening at 4242"  

for _ in range(0,thread_num):  
    t=threading.Thread(target=worker)  
    t.setDaemon(1)  
    t.start()  

while 1:  
    conn,addr=s.accept()  
    print "Connection come from ("+str(addr[0])+":"+str(addr[1])+")"  
    q.put((conn,addr))  

q.join()
