This code shows how to create an https bridge with flask that sends json commands from network to json ipc server running locally #python #mpv

mpv-http-ipc-json-flask-bridge.py

#!/usr/local/env python
# coding: utf8

from flask import Flask, jsonify, request, abort
import os, subprocess, json


ASSETS_DIR = os.path.dirname(os.path.abspath(__file__))
app = Flask(__name__)

def compose_command_json(json_data):
    command = "echo "
    command += "\'" + json_data + "\'" # this should be a valid json
    command += " | socat - /tmp/mpvsocket" # hardcoded named pipe for now
    return command


# ROUTES

@app.route('/', methods = ['POST'])

    return 'Flask is running!'


@app.route('/json/', methods = ['POST'])

    #print(request.json)

    #print(request.json["command"])

        command = compose_command_json(request.data.decode("utf8")) # compose command with json if is valid json
        process_return = subprocess.check_output(command, shell=True)
        return str(process_return), 200
    else:
    	abort(400) #abort() works without return. Otherwise use `return "Page not found", 404` or even `return "Bad request", 400` manually


# START SERVER

if __name__ == '__main__':
    #context = ('public.pem', 'private.pem') #certificate and key files
    #app.run(debug=True, ssl_context=context)
    
    app.run(debug=False, ssl_context="adhoc") # we will use adhoc mode, easier for develop and not a problem unless you try it with browser or browser-based extension.
