Jean-Paul,
I just start to learn Twisted. Here is my simple case: I can find
the data sent by clients in dataReceived but I don't know which
client/which port the data is from. After I know where the data comes
from, I can do different things there, for example, write them into
different files via bsddb. I am not sure if it is the correct way to
do it.
def dataReceived(self, data):
# Accumulate the new data in our list
self.received.append(data)
# And then echo the entire list so far back to the client
self.transport.write(''.join(data))
print "============> data: ", data
print " which Port? : ", self.factory.port # unforunately it is
an object here.
# if Port == 2001:
# write the data into a file via bsddb
# if Port == 2002:
# write the data into another file via bsddb
# etc .....
