Long polling /recieve post request #1775

Open pkyad opened 4 years ago

pkyad commented 4 years ago

I have an old server : ubuntu 14.04 (python 2.7) crossbar (18.4.1) where i configured the long poll

Perfect setup / working after doing some code changes ( implimented render_OPTIONS ) at several places in longpoll.py router to fix the CORS error

class WampLongPollResourceOpen(Resource):

  def render_OPTIONS(self, request):
     request.setHeader(b'Access-Control-Allow-Headers', b"Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With")
     request.setHeader(b'access-control-allow-origin', b"*")
     return b""

On the new server Ubuntu 18.04 (crossbar 20.4.2)

with the same changes and most of the things are still fine but there is some issue with polling

/ws/recieve/

/ws/open/ , /ws/send/, works fine

But since /recieve/ is not working the entire connection resets itself

Nothing urgent for us but really wanted to move the services to new one. Please help

is there a problem with long-poll on the latest, unmodified crossbar release? if so, best would be to come up with a test case that reproduces this.

we don't support old crossbar releases or custom modified versions

Yes, the unmodified version (latest version) gives the CORS error over SSL connection but even if we fix the CORS by implimenting render_OPTIONS function the /recieve/ url is the one which never responds.

other urls /send/ , /open/ etc does get the response.
