JSONRPC2Protocol

✓ from pyls_jsonrpc.manager import JSONRPC2Protocol

✗ from jsonrpc.manager import JSONRPC2Protocol

Basic JSON RPC 2.0 server that reads from stdin and writes to stdout, handling a 'hello' method.

import asyncio from jsonrpc.server import JSONRPC2Server from jsonrpc.manager import JSONRPC2Protocol async def handle_request(protocol, data): request = protocol.parse_request(data) if request.method == "hello": response = protocol.create_response(request, "world") return response.serialize() else: error = protocol.create_error_response(request, -32601, "Method not found") return error.serialize() server = JSONRPC2Server(handle_request) asyncio.run(server.run()) print("Server running on stdin/stdout")

Debug

Known issues

breakingIn version 0.3.0, the built-in `json` module was replaced with `ujson`. This may cause compatibility issues if your code depends on custom JSON encoders/decoders or uses different JSON library features. `ujson` is not available by default on Windows; install it separately or use a workaround.

fix

If you need the standard json module, pin to version 0.2.0 or manually monkey-patch. On Windows, install ujson with pip install ujson.

affects: >=0.3.0

gotchaThe library's protocol expects a specific JSON RPC 2.0 format. If you send malformed requests (e.g., missing 'jsonrpc' field or invalid id), the server may hang or raise cryptic errors.

fix

Ensure your JSON RPC messages strictly follow the spec: include 'jsonrpc':'2.0', 'method', 'id' (or null for notifications), and proper 'params'.

affects: all
