How to make simple python UDP socket server?

I am trying to make a python socket server based on UDP.
The point is that we need to receive data from the Java client socket server and the python UDP protocol socket server must throw JSON data to React in the front.
I have the level of knowledge to make a simple UDP chat server, so I'm worried a lot now.
I am currently reading the django channels official documentation.
Does django-channeles provide easy configuration to use UDP protocol as well?

There is a specification for raw UDP in the docs. UDP is not reliable as some of the data may be lost, so it is not widely used. If you must use it, you have to implement a UDP consumer based on the specification using the websocket consumers as a template

Is there a way to use web sockets with ec2 instance?

I'm currently developing a multiplayer gaming app using flutter framework and AWS services. Connections are established through web sockets. I really don't understand how to establish these connections with ec2. Do I need to develop api using node.js or python?
Please note down if there are any useful links.

WebSockets, on the other hand, allow for sending message-based data, similar to UDP, but with the reliability of TCP. WebSocket uses HTTP as the initial transport mechanism, but keeps the TCP connection alive after the HTTP response is received so that it can be used for sending messages between client and server. WebSockets allow us to build “real-time” applications without the use of long-polling.

Seems like something that will work fine for AWS ingress.

How can I examine the network communications of the Python HTTP Client?

I'm trying to isolate a bug that exists either in Python's httplib2 HTTP client or an API. (First guess is the API.) While using httplib2 to POST data to a RESTful API, I'm getting a 401 response status (no authorization) and saving data to the API.
I'd like to examine the HTTP request and response to the client, the very strings put onto and received from the network. The httplib2 code seems too involved to easily capture the values from within it, and might possibly miss the bug.
It seems quicker to look at the network communications with the client. Is there some tool I can use to monitor the client's communications with the local network socket?

I use http://www.charlesproxy.com for all my network debugging.

http://www.wireshark.org/ enables you to monitor local sockets too.
I was able to monitor local loopback even on windows using trick whit adding route.

Or you can just write raw socket server that listen on client side on one port and send data to server on other port and vice versa and prints out all data. It should not take more than dozen of lines of code

How can I implement a secure WebSocket (wss://) server in Python?

I want to serve a real-time stream that has to be securely encrypted due to sensitive data.
I've successfully got normal WebSockets streaming using both gevent and gunicorn as direct frontends, but now I need to make it secure, and am looking for either of these:
A server that can serve secure WebSocket connections that are proxied to (for example) gunicorn which listens for non-secure WebSocket connections.
A framework that can serve secure WebSocket connections directly. I've been looking at Tornado and believe it can handle it, but I'm still open to suggestions.
I use ZeroMQ for the PUB/SUB pattern. If there is a good WebSocket protocol implementation for ZeroMQ, that would be great.
Speed is not super important here as the number of connections will be low. However, the integrity of the data is important.

Assuming that you have your app running correctly over non-SSL Tornado WebSockets, change the listen call from:
app.listen(args.listen_port, args.listen_interface)
to:
app.listen(args.listen_port, args.listen_interface, ssl_options={
"certfile": os.path.join(lib_dir, "mydomain.crt"),
"keyfile": os.path.join(lib_dir, "mydomain.key"),
})
where "mydomain.crt" and "mydomain.key" are your usual SSL certificate files, and lib_dir is the directory they live in.
Don't forget to change the client to use "wss:"
Also note that the port you specify in the listen call will still be used if you specify ssl_options. i.e. it will not revert to listening on port 443.

You can check out the websockify project. Websockify is a proxy that allows a WebSockets capable browser to communicate with a raw binary TCP server. It does this by base64 encoding all traffic to/from the browser. However, the project is modular and the websocket.py file is a general WebSocket server that is designed to be extended (and there a couple of included tests that show how this works). It would be fairly easy to disable the base64 encoding if that is not needed for you project.
Websockify also includes a Javascript library 'websock.js' which is designed to interact with websockify. It will transparently fallback to using web-socket-js (Flash based) if the browser does not have native WebSocket support.
Websockify supports secure (TLS/wss) connections and also is able to answer Flash security policy requests inline on the same port.
Disclaimer: I made websockify.

Take a look at the standalone websockets server of the pywebsocket project supported by Google.
Note that this Python module uses CGIHTTPServer so you need to tweak it to make it secure. I had a similar requirement for a project I was involved in some months ago, so I forked the standalone.py module and removed the dependencies with CGI stuff but I haven't tested secure connections very much.
Maybe you can import OpenSSL.SSL and set up a WebSocketServer as it is in my script. It should use a WebSocketRequestHandler with the proper configuration of use_tls, private_key and certificate in order to implement TLS (Transport Layer Security).
Read the source code. I think you can extend it to meet your needs.

We use Tornado and Tornadio for our realtime app, and I just switched on SSL for websockets, as well as all the other realtime socket.io protocols. It took me just over an hour! more info here:

In server side add this to Tornado:
tornadio2.server.SocketServer(application, ssl_options={
"certfile": "server.crt",
"keyfile": "server.key",
})
In client side, refer to this link:
wss://www.example.com:2201/ws, where the 2201 is the secure Websocket's TLS port.

Implement a Web based Client that interacts with a TCP Server

EDIT:Question Updated. Thanks Slott.
I have a TCP Server in Python.
It is a server with asynchronous behaviour. .
The message format is Binary Data.
Currently I have a python client that interacts with the code.
What I want to be able to do eventually implement a Web based Front End to this client.
I just wanted to know , what should be correct design for such an application.

Start with any WSGI-based web server. werkzeug is a choice.
The Asynchronous TCP/IP is a seriously complicated problem. HTTP is synchronous. So using the synchronous web server presenting some asynchronous data is always a problem. Always.
The best you can do is to buffer things and have two processes in your web application.
TCP/IP process that collects data from the remove server and buffers it in a file (or files) somewhere.
WSGI web process which handles GET/POST processing.
GET requests will fetch some or all of the buffer and display it.
POST requests will send a message to the TCP/IP server.

For Web-based, talk HTTP. Use JSON or XML as data formats.
Be standards-compliant and make use of the vast number of libraries out there. Don't reinvent the wheel. This way you have less headaches in the long run.

if you need to maintain a connection to a backend server across multiple HTTP requests, Twisted's HTTP server is an ideal choice, since it's built to manage multiple connections easily.
