将超时添加到python服务器时出现非阻塞错误

Question

我正在用python写一个简单的TCP服务器，并试图输入一个超时。我当前的代码：

import socket


def connect():
    HOST = ''                 # Symbolic name meaning the local host
    PORT = 5007             # Arbitrary non-privileged port
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind((HOST, PORT))
    s.listen(1)
    s.settimeout(5)
    conn, addr = s.accept()
    print 'Connected by', addr
    return conn

conn = connect()

while 1:
    data = conn.recv(1024)
    if not data: break
    print data
conn.close()

问题是当我尝试连接时，在data = conn.recv（1024）时出现错误

error: [Errno 10035] A non-blocking socket operation could not be completed immediately

代码可以正常工作而不会超时。

您可以开启阻止：

    # ...
    conn.setblocking(1)
    return conn
# ...
