problem with GST

[hcoolh]

Hi
Could you please help me with this ? I started sample_worker.py:
python kaldigstserver/worker.py -u ws://localhost:8888/worker/ws/speech -c sample_worker.yaml
and then used sample_client.py to test it. I changed the 50th line in sample_client.py to this:
ws = MyClient('ws://localhost:8888/client/ws/speech?%s' ...

here is the output of worker:

Thank you very much.

Thanks for noticing. I think the problem was caused by a bug in sample_client.py which caused the content type not to be sent.

I've deleted the outdated and ugly sample_client.py and added client.py. I also updated the main README and added a note how to test the server using kaldigstserver/client.py. Hope this helps.

Seems to be fixed.
