This post uses Jsonrpcserver 5 which requires Python 3.8+.

flask json

We’ll use Django to take JSON-RPC requests. It should respond to “ping” with “pong”.

Install jsonrpcserver to process the JSON-RPC requests:

pip install jsonrpcserver

Create a views.py:

from django.http import HttpResponse
from django.views.decorators.csrf import csrf_exempt
from jsonrpcserver import method, Result, Success, dispatch


@method
def ping() -> Result:
    return Success("pong")


@csrf_exempt
def jsonrpc(request):
    return HttpResponse(
        dispatch(request.body.decode()), content_type="application/json"
    )

Start the development server on port 5000:

$ python manage.py runserver 5000

Quit the server with CONTROL-C.

Test it

$ curl -X POST http://localhost:5000 -d '{"jsonrpc": "2.0", "method": "ping", "id": 1}'
{"jsonrpc": "2.0", "result": "pong", "id": 1}
