Port 8080 hardcoded when running client_aio.py, can't run on 9090 #941

Closed NumesSanguis closed 6 years ago

NumesSanguis commented 6 years ago

I want to run my Python client/publisher on port 9090 (or any other port), because some other program is running on 8080.

My project is setup as followed using Docker (following https://crossbar.io/docs/Getting-Started/):

Message broker on port 9090:

  1. git clone https://github.com/crossbario/crossbar-starter.git
  2. cd crossbar-starter/crossbar
  3. Change all occurrences of 8080 to 9090 in .crossbar/config.json and Makefile
  4. Open webbrowser on http://localhost:9090/
  5. Succesfully get JavaScript output

Python pub/sub on port 9090:

  1. cd ../autobahn-python
  2. In app/run comment python -u client_tx.py and uncomment python -u client_aio.py
  3. Open app/client_aio.py and change 2 8080 to 9090.
url = os.environ.get('CBURL', u'ws://localhost:9090/ws')
parser.add_argument('--url', dest='url', type=six.text_type, default=url, help='The router URL (default: "ws://localhost:9090/ws").')
  1. Run make start and get the following error:
make start
docker run -v /*file_path*/app:/app  -it --rm --link crossbar crossbario/autobahn-python
Traceback (most recent call last):
  File "client_aio.py", line 144, in <module>
    runner.run(ClientSession)
  File "/usr/local/lib/python3.6/site-packages/autobahn/asyncio/wamp.py", line 259, in run
    (transport, protocol) = loop.run_until_complete(coro)

    return (yield from fut)
  File "/usr/local/lib/python3.6/asyncio/selector_events.py", line 481, in _sock_connect_cb
    raise OSError(err, 'Connect call failed %s' % (address,))
ConnectionRefusedError: [Errno 111] Connect call failed ('172.17.0.2', 8080)
Makefile:4: recipe for target 'start' failed
make: *** [start] Error 1

Problem Seems like port 8080 is hardcoded somewhere when using asyncio version of client.

With client_tx.py it is also happening:

When running everything normal (including message broker on 8080), except for changing in these 2 lines 8080 to 9090 in client_aio.py:

url = os.environ.get('CBURL', u'ws://localhost:9090/ws')
parser.add_argument('--url', dest='url', type=six.text_type, default=url, help='The router URL (default: "ws://localhost:9090/ws").')

Everything still works. This means that these values are ignored and a hard coded port is used.

I just tried and everything is working fine for me.

The first line reads the websocket url from environment variable CBURL and fallbacks to ws://localhost:9090/ws. So you probably have CBURL in the environment.

Just replace url = os.environ.get('CBURL', u'ws://localhost:9090/ws') with url = u'ws://localhost:9090/ws' and you should have no issue.

You can ignore the port number in second line, that's just a help comment and does not affect functionality.

NumesSanguis commented 6 years ago

I changed the url as you suggested url = u'ws://localhost:9090/ws', and indeed it tries to connect over port 9090, but it still can't connect. I tried again with a fresh download and the steps I described in the first post.

While the javascript works fine on port 9090.
