Implement a Web based Client that interacts with a TCP Server.

Question

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.

Answer 1

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.

Answer 2

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.

1. TCP/IP process that collects data from the remove server and buffers it in a file (or files) somewhere.

2. 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.

Answer 3

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.
