JSONRPCBase 0.1.2

Intro

Simple JSON-RPC service without transport layer

This library is intended as an auxiliary library for easy an implementation of JSON-RPC services with Unix/TCP socket like transport protocols that do not have complex special requirements. You need to utilize some suitable transport protocol with this library to actually provide a working JSON-RPC service.

Features

• Easy to use, small size, well tested.

• Supports JSON-RPC v2.0. Compatible with v1.x style calls with the exception of v1.0 class-hinting.

• Optional argument type validation that significantly eases development of jsonrpc method_data.

Example

Example usage:

import jsonrpcbase

chat_service = jsonrpcbase.JSONRPCService()

def login(username, password, timelimit=0):
    (...)
    return True

def receive_message(**kwargs):
    (...)
    return chat_message

def send_message(msg):
    (...)

if __name__ == '__main__':

    # Adds the method login to the service as a 'login'.
    chat_service.add(login, types=[basestring, basestring, int])

    # Adds the method receive_message to the service as a 'recv_msg'.
    chat_service.add(receive_message, name='recv_msg', types={"msg": basestring, "id": int})

    # Adds the method send_message as a 'send_msg' to the service.
    chat_service.add(send_message, 'send_msg')

    (...)

    # Receive a JSON-RPC call.
    jsonmsg = my_socket.recv()

    # Process the JSON-RPC call.
    result = chat_service.call(jsonmsg)

    # Send back results.
    my_socket.send(result)
