    request = {'jsonrpc': '2.0', 'method': 'sub', 'params': [42, 23], 'id': 1}

    async with ClientSession() as session:
        async with session.post(url + '/post', json=request) as resp:
            response = await resp.json()
            print(response['result'])  # 19

        async with session.ws_connect(url + '/ws') as ws:
            await ws.send_json(request)
            response = await ws.receive_json()
            print(response['result'])  # 19
