Python 套接字超时错误

Question

我正在用Python 2.7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：属性错误："_socketobject"对象没有属性"超时"

我不明白为什么没有超时属性？！

事实上，我正在研究智力，也没有这样的属性。

任何建议将不胜感激

Answer 1

socket模块有一个timeout类。套接字对象 mysocket（类型 socket.socket ）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 *。

我有python 2.7，它在ipython上对我有用
