At the moment I'm playing with the WAMP proto, and I'm curious if something like this is possible, because I can't get it to work: 1.Having WAMP router written in c# (WampSharp) : const string location = "ws://127.0.0.1:9999/wsdemo"; try { using (IWampHost host = new DefaultWampHost(location)) { IWampHostedRealm realm = host.RealmContainer.GetRealmByName("realm1"); host.Open(); Console.WriteLine("Host is running on : " + location); } } catch(Exception exc) { Console.WriteLine("Error : " + exc.ToString()); } 2.Having component written in python : import random from twisted.internet.defer import inlineCallbacks from autobahn.twisted.util import sleep from autobahn.twisted.wamp import ApplicationSession, ApplicationRunner class Component(ApplicationSession): """ An application component that publishes events with no payload and with complex payload every second. """ @inlineCallbacks def onJoin(self, details): print("session attached") counter = 0 while True: num = random.randint(0, 100) print("publishing : com.myapp.topic1", num) self.publish(u'com.myapp.topic1', num) counter += 1 yield sleep(1) if __name__ == '__main__': runner = ApplicationRunner(url=u"ws://127.0.0.1:9999/wsdemo", realm=u"realm1") runner.run(Component) When I run python script, I'm getting the error : 2017-02-20T19:49:46+0100 Main loop terminated. 2017-02-20T19:49:46+0100 Traceback (most recent call last): 2017-02-20T19:49:46+0100 File "C:\Program Files (x86)\JetBrains\PyCharm Educational Edition 1.0.1\helpers\pydev\pydevd.py", line 2199, in <module> 2017-02-20T19:49:46+0100 globals = debugger.run(setup['file'], None, None) 2017-02-20T19:49:46+0100 File "C:\Program Files (x86)\JetBrains\PyCharm Educational Edition 1.0.1\helpers\pydev\pydevd.py", line 1638, in run 2017-02-20T19:49:46+0100 pydev_imports.execfile(file, globals, locals) # execute the script 2017-02-20T19:49:46+0100 File "D:/Programming/Astronomy/Dev/ZenithPlatform/backbone/local/tests/wamp.py", line 41, in <module> 2017-02-20T19:49:46+0100 runner.run(Component) 2017-02-20T19:49:46+0100 File "C:\Python27\lib\site-packages\autobahn\twisted\wamp.py", line 312, in run 2017-02-20T19:49:46+0100 raise connect_error.exception 2017-02-20T19:49:46+0100 twisted.internet.error.ConnectionRefusedError: Connection was refused by other side: 10061: No connection could be made because the target machine actively refused it.. As per The "Running a WAMP Router" guide The component we’ve created attempts to connect to a WAMP router running locally which accepts connections on port 8080, and for a realm realm1. Our suggested way is to use Crossbar.io as your WAMP router. There are other WAMP routers besides Crossbar.io as well. Could something like this be achieved at all? Continue reading...
