Python Flask Script With GUI in WebPage
by jttolleson from LinuxQuestions.org on (#6M1PK)
Hello all - Jayson here and I am designing a program to make a 3d solid and view it in browser, with Python on my Virtual Machine running Debian.
I have had many issues with the GUI aspect of my program, in browser ...and will continue to post updates here soon... also any help or change in direction of this code would be greatly appreciated.
Code:import os
import subprocess
from subprocess import Popen, PIPE, STDOUT
from flask import Flask, Response, request, render_template, redirect, url_for
subprocess.Popen('sudo npx kill-port 8086 && sudo npx kill-port 8087', shell=True, stdout=subprocess.PIPE, stderr=STDOUT)
cmd = ["sudo Xvfb :2 -screen 0 1440x720x24 &, sudo x11vnc -rfbport 8086 -forever -shared -display :2 /var/www/cgi-bin/stl-viz.py -gone 'killall Xvfb' -nopw &, cd ~/snap/novnc/current; novnc --listen 8086 --cert 'lftr.biz.crt' --key 'lftr.biz.key' --vnc 0.0.0.0:8087"]
app = Flask(__name__)
app.url_map.strict_slashes = False
@app.route('/stl')
def out():
def output():
yield """<html><head>

show(m, camera_position=(-60., -160, 120), camera_target=(0., 0, 40), light=(-60, -160, 120))when i run:
Code:sudo python3 console-stl-viewer.pyI get a browser window @ my https://lftr.biz:8080/stl that refreshes an iframe that doesent have https://lftr.biz:8087 in 'er.
so.....if i go there on the web when its running its not working either..
Must be my GUI Command?
