python socket recv逾時,Python套接字逾時錯誤

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

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()

I am getting the following error.

except mySocket.timeout:

AttributeError: '_socketobject' object has no attribute 'timeout'

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

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

Any suggestion will be greatly appreciated

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

Try this:

except timeout:

print 'Request timed out!'

mySocket.close()

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