python实现单线程多任务非阻塞TCP服务端
本文实例为大家分享了python实现单线程多任务非阻塞TCP服务端的具体代码，供大家参考，具体内容如下
# coding:utf-8
from socket import *
# 1.创建服务器socket
sock = socket(AF_INET, SOCK_STREAM)
# 2.绑定主机和端口
addr = ('', 7788) #
sock.bind(addr)
# 3. 设置最大监听数目，并发
sock.listen(10)
# 4. 设置成非阻塞
sock.setblocking(False)
# 保存客户端socket
clientAddrList = []
# print(sock.)
while 1:
try:
clientSocket, clientAddr = sock.accept()
except:
pass
else:
print("一个新客户端到来：%s" % str(clientAddr))
clientSocket.setblocking(False)
clientAddrList.append((clientSocket, clientAddr))
for clientSocket, clientAddr in clientAddrList:
try:
recvData = clientSocket.recv(1024)
except:
pass
else:
if len(recvData) > 0:
print("%s:%s" % (str(clientAddr), recvData))
else:
clientSocket.close()
clientAddrList.remove((clientSocket, clientAddr))
print("%s 已经下线" % str(clientAddr))
