create online vnc client

[hmadadian]

hi
I am working on a project that gets host, port and password params from an HTTP request and then runs websocketify command and connects to the mention vnc host and then returns the novnc URL.
But this does not work. Can anyone please help to solve this issue or tell me an alternative way?

You are probably looking for what's discussed on #1159

Yes, something like that. But I did it another way.
I use python in my backend so I could use it to establish the proxy.
so first I install websockify with
pip install websockify

Then I import the websockify Lib and use WebSocketProxy class. With using multiprocessing I could handle what I want, and the result is something like this:

import socket, threading
from multiprocessing import Process
from websockify.websocketproxy import WebSocketProxy
import os

# Handle Requests
class ClientThread(threading.Thread):
    def __init__(self,clientAddress,clientsocket):
        threading.Thread.__init__(self)
        self.csocket = clientsocket

    def run(self):
        msg = ''
        while True:
            try:
                data = self.csocket.recv(65536)
                msg = data.decode()
            except Exception as e:
                exit()
            break
        try:
            # Get Requested host and port
            vnchst = msg.split(":")
            # if already port is busy kill it
            getpid = os.popen('lsof -ti tcp:' + str(vnchst[1])).read()
            if (getpid != ""):
                pids = getpid.split("\n")
                for i in pids:
                    if (i != ''):
                        os.popen('kill -9 ' + str(i)).read()
            # Establish the proxy for requested host and port
            p = P(str(vnchst[0]),int(vnchst[1]))
            p.start()
            p.join()
        except Exception as e:
            exit()

# MultiProcess Part
class P(Process):
    def __init__(self , host , port):
        super(P, self).__init__()
        self.host = host
        self.port = port

    def run(self):
        server = WebSocketProxy(target_host=str(self.host) , target_port=int(self.port) , listen_port=int(self.port) , web="/root/noVNC/")
        server.start_server()

LOCALHOST = "localhost"
PORT = 8081
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server.setsockopt(socket.SOL_SOCKET, socket.SO_RCVBUF, 65536)
server.bind((LOCALHOST, PORT))
while True:
    server.listen(1)
    clientsock, clientAddress = server.accept()
    newthread = ClientThread(clientAddress, clientsock)
    newthread.start()
