Python 套接字超时错误答案

【问题描述】：

我正在 Python 2.7 中编写一个非常简单的 udp 套接字连接

服务器端已启动并正在运行。我在客户端遇到了麻烦。

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'

看不懂怎么没有timeout属性？！

其实我看的是智能感知，也没有这个属性。

任何建议将不胜感激

【解决方案1】：

socket 模块有一个timeout 类。您的套接字对象mysocket（socket.socket 类型）没有timeout 属性。

试试这个：

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

请注意，您还应该小心以这种方式使用import *。

哇，非常感谢jozzas。这正是我所需要的。

我有 python 2.7，它适用于 ipython

感谢 ronak 的意见。你有什么建议为什么它对我不起作用？
