WxPython in web with a cgi server

[jttolleson]

Yes, Hello again ---Jayson:

wxPython will work in with IPython in Python3. Especially, in deb or ubuntu

and this will be my direction, however the same problem exists. My x-display in web.

I will post again as this thread continues, with a simple script that will have the same issue. the x display.

---

Ok, well here we go: IPython
sudo nohup python3 /var/www/webserver3.py &

import os, sys
from http.server import HTTPServer, CGIHTTPRequestHandler
import ssl
webdir = '/var/www/'
port = 443
os.chdir(webdir)
srvaddr=('', port)
srvobj = HTTPServer(srvaddr, CGIHTTPRequestHandler)
srvobj.socket = ssl.wrap_socket (srvobj.socket, keyfile='/var/security/35.236.122.135.key', certfile='/var/security/35.236.122.135.crt', server_side=True)
CGIHTTPRequestHandler.have_fork=False # Force the use of a subprocess
srvobj.serve_forever()

sudo python3 /var/www/cgi-bin/lftr/wxgui.py

#!/usr/bin/env python3
import cgitb
cgitb.enable
"""

To run this do:

now this code: will run IPython in a .py script on the cgi-server

#!/usr/bin/env python3
import cgitb
cgitb.enable
import IPython
IPython.start_ipython(argv=[])

I hope we still can have an open mind about this being fun and useful structure to run interactive web gui scripting which would be a PLUS...


and this becomes a complicated question: b/c sudo IPython /var/www/cgi-bin/lftr/wxgui.py --gui=wx
can be run as something like this: sudo python3 /var/www/cgi-bin/lftr/wxgui.py if it is including some IPython ----

#!/usr/bin/env python3
import cgitb
cgitb.enable

import IPython
IPython.start_ipython(argv=[]) # this will start IPython, however i am unsure how to input the entire script

import IPython.display #this will access  display for a gui of wx hopefully
gui=wx #incorrect code

anyone? - - - for a round of direction or help??? i still get the display error no matter what
so I set the Display Environment variable to localhost:0 with no noticible effect.
