Example 1 with JsonRpcError

use of co.rsk.jsonrpc.JsonRpcError in project rskj by rsksmart.

the class RskWebSocketJsonRpcHandler method channelRead0.

@Override

    ByteBuf content = msg.copy().content();
    try (ByteBufInputStream source = new ByteBufInputStream(content)) {

        RskWebSocketJsonParameterValidator.Result validationResult = parameterValidator.validate(jsonNodeRequest);
        RskJsonRpcRequest request = mapper.treeToValue(jsonNodeRequest, RskJsonRpcRequest.class);
        JsonRpcResultOrError resultOrError = null;
        if (validationResult.isValid()) {
            // TODO(mc) we should support the ModuleDescription method filters
            resultOrError = request.accept(this, ctx);
        } else {
            resultOrError = new JsonRpcError(JsonRpcError.INVALID_PARAMS, validationResult.getMessage());
        }
        JsonRpcIdentifiableMessage response = resultOrError.responseFor(request.getId());
        ctx.writeAndFlush(new TextWebSocketFrame(getJsonWithTypedId(jsonNodeRequest, response)));
        return;
    } catch (IOException e) {
        LOGGER.trace("Not a known or valid JsonRpcRequest", e);
        // We need to release this resource, netty only takes care about 'ByteBufHolder msg'
        content.release(content.refCnt());
    }
    // delegate to the next handler if the message can't be matched to a known JSON-RPC request
