Turbogears with gevent-socketio: request Key Error

I try to use gevent.socketio with my TurboGears 2 Website:

in the ini-file i use 

[server:main]
use = egg:gevent-socketio#paster
transports = xhr-multipart, xhr-polling, websocket
host = 0.0.0.0
port = 8080

when i try to access the controller in the Webbrowser:

@expose('wago.templates.test')
def index(self):
  socketio_manage(request.environ, {"/stat": StatNamespace}, request=request) 
  return dict()

i get the following error:

Traceback (most recent call last):

I used several tutorials for pyramid to introduce myself to gevent-socketio. I tried it with older versions from TurboGears2, gevent and gevent-socketio, i also tried this module but always the same error. i'm pretty new to sockets, so maybe i'm just missing something obvious

Solution

  • the gevent-socketio recognizes socket requests only from a specific url (socket.io/1/) because TurboGears uses the python function names as url it is not posible to us "." or "1" on the regular way. A simple solution: 

        @expose()
    def _default(self, *args):
      args = list(args)
      if "socketio" in request.environ:
        #do socketio stuff...
      else:
        abort(404)
