Python套接字超时错误 [英] Python Socket timeout error

问题描述

我在Python 2.7中编写了一个非常简单的udp套接字连接

I am writing a very simple udp socket connection in Python 2.7

服务器端已启动并正在运行. 我在客户端遇到了麻烦.

The server side is up and running. I have trouble on the client side.

from socket import *

serverName = '127.0.0.1'
serverPort = 5444
counter = 1;

while counter < 55:
    mySocket = socket(AF_INET,SOCK_DGRAM)

    try:
        mySocket.settimeout(1.0)
        message = raw_input('')
        mySocket.sendto(message,(serverName, serverPort))
        modifiedMessage, serverAddress = mySocket.recvfrom(1024)
    except mySocket.timeout:
        print 'Request timed out!'
        mySocket.close()
    else:   
        print 'Server Response:  '
        print modifiedMessage   

    mySocket.close()

我收到以下错误. 除了mySocket.timeout: AttributeError:'_socketobject'对象没有属性'timeout'

I am getting the following error. except mySocket.timeout: AttributeError: '_socketobject' object has no attribute 'timeout'

我不明白为什么没有超时属性?！

I can't understand how come there is no timeout attribute?!

实际上，我正在查看智能，并且也没有这样的属性.

In fact I am looking at the intelisense and there is no such attribute too.

任何建议将不胜感激

推荐答案

socket模块具有一个timeout类.您的套接字对象mysocket(类型为socket.socket)没有timeout属性.

The socket module has a timeout class. Your socket object, mysocket (of type socket.socket), does not have a timeout attribute.

尝试一下:

except timeout:
    print 'Request timed out!'
    mySocket.close()

请注意，以这种方式使用import *时也应小心.

Note that you should also be careful about using import * in this manner.
