I am having trouble using ClientFactory to communicate from within a server. Specifically, I can't figure out the proper way to exit from the client process.
Included is some example code illustrating the problem I am having. It is the simple echo server example, but when someone sends some text to the server, I am trying to talk to an SMTP server to send an email. This is just an example (there are probably better ways to fire off an email), but you get the idea. The client code never "exits" and if I try to use reactor.stop() it causes a traceback.
reactor.run() enters the twisted mainloop. reactor.stop() causes the mainloop to terminate in the near future. You cannot nest calls to the mainloop (nor do you need to do so).
So how do I properly exit from this client code, or (being new to twisted) am I going about this in the entirely wrong way? Thanks.
#!/usr/bin/env python
from twisted.internet import reactor from twisted.internet.protocol import Protocol, ClientFactory, ServerFactory import sys
class Echo(Protocol): """This is just about the simplest possible protocol"""
def dataReceived(self, data): "As soon as any data is received, write it back." self.transport.write(data) factory2 = MySMTPClientFactory() host = 'localhost' port = 25 reactor.connectTCP(host, port, factory2) reactor.run()
Remove the above call to "reactor.run() and see what happens.
print "Returned from sending email" # ^ Never gets to this point
class MySMTP(Protocol): [snip]
I don't understand why you aren't using twisted.protocols.smtp.
