Hi,
Thanks for your reply Terry.
I am still not done with this problem. Please tell me can a server send a
list object using socket programming to the requesting client?
If yes, how? I am getting the following error
TypeError: send() argument 1 must be string or read-only buffer,
not list
For sending list object I tried the following code: -
Server Code: -
-
someList = [ 1, 2, 7, 9, 0 ]
pickledList = pickle.dumps ( id(someList) )
# Our thread class:
class ClientThread ( threading.Thread ):
# Override Thread's __init__ method to accept the parameters needed:
def __init__ ( self, channel, details ):
self.channel = channel
self.details = details
threading.Thread.__init__ ( self )
def run ( self ):
print 'Received connection:', self.details [ 0 ]
self.channel.send ( pickledList )
self.channel.close()
print 'Closed connection:', self.details [ 0 ]
# Set up the server:
server = socket.socket ( socket.AF_INET, socket.SOCK_STREAM )
server.bind ( ( '', 2727 ) )
server.listen ( 5 )
# Have the server serve forever:
while True:
channel, details = server.accept()
print channel, details
ClientThread ( channel, details ).start()
Client Code: -
-
class ConnectionThread ( threading.Thread ):
def run ( self ):
# Connect to the server:
client = socket.socket ( socket.AF_INET, socket.SOCK_STREAM )
client.connect ( ( 'localhost', 2727 ) )
#print 'Connected!!',client
# Retrieve and unpickle the list object:
lst= pickle.loads ( client.recv ( 1024 ) )
# Close the connection
client.close()
# Let's spawn a few threads:
for x in xrange ( 10 ):
ConnectionThread().start()
-
In the above code I am able to get the id of the server List in the
client, but can not access the content at the client. And if I send the
pickled list to the client, it creates a new list at the client end, which
is not desirable.
Please suggest how to share a in-memory list object across two different
programs?
Thanks.
Piyush.
