Minimal Flask server for a JSON API

server.py

from flask import Flask
from flask.helpers import request
from traceback import format_exc

SERVER = Flask(__name__)
PORT = 5000
# SSL_CONTEXT = '/etc/ssl/certificate.crt', '/etc/ssl/private.key'
SSL_CONTEXT = None

def api(data: dict):
	return {'foo': 'bar'}  # TODO

@SERVER.route('/', defaults={'path': ''}, methods=['GET', 'POST'])
@SERVER.route('/<path:path>', methods=['GET', 'POST'])
def catch_all(path: str):
	json_data = request.get_json()
	if 'X-Forwarded-For' in request.headers:
		ip = request.headers['X-Forwarded-For']
	else:
		ip = request.remote_addr
	data = {
		**request.headers,
		**request.cookies,
		**request.files,
		**request.values,
		**({} if json_data is None else json_data),
		'ip': ip,
		'endpoint': path[4:] if path.startswith('api/') else path
	}
	try:
		res = api(data), 200
	except:
		res = {
			'error': 'unknownError',
			'parameters': format_exc().strip().split('\n')
		}, 500
	return res

SERVER.run(host='0.0.0.0', port=PORT, debug=True, ssl_context=SSL_CONTEXT)
