python - Obtain JSON request in Bokeh server application -

i direct user page hosted bokeh server along bit of metadata. example might want direct user to

http://my-server/my-page?var=value 

i {'var': 'value'} request in bokeh server application code on python side can respond accordingly.

is possible? if so, how?

a bokeh core dev pointed me documentation page:

https://bokeh.pydata.org/en/latest/docs/user_guide/server.html#accessing-the-http-request

in particular, available on document object:

# request.arguments dict maps argument names lists of strings, # e.g, query string ?n=10 result in {'n': [b'10']}  args = curdoc().session_context.request.arguments  try:   n = int(args.get('n')[0]) except:   n = 200
