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()
