async4jsonrpc

This library is an asynchronous python library for the JSON-RPC specification.

It is licensed under the Apache License, Version 2.0 (http://www.apache.org/licenses/LICENSE-2.0.html).

Installation

Install from PyPi via pip:

pip3 install async4jsonrpc

Features

Compliant with the JSON-RPC 2.0 specification
High performance by asyncio and coroutine
Json serialization support via jsonpickle

Usage

Server Usage

server-test.py

from async4jsonrpc.server import JsonRpcServer

# create RPC json server
server = JsonRpcServer()
# registers a function to respond to RPC requests.
server.register_function(lambda x, y: x + y, 'add')
server.register_function(lambda x: x, 'ping')
# start to serve RPC request
server.serve('localhost', 8080)

Client Usage

client-test.py

import asyncio
from async4jsonrpc.client import JsonRpcClient

# create RPC json client
client = JsonRpcClient('127.0.0.1', 8080)

async def call_rpc(i):
    # rpc: send rpc request
    r = await client.ping(f'hello {i}')
    print(r)

asyncio.run(call_rpc('shi'))

Json serialize

I use jsonpickle library for serialization and deserialization of complex Python objects to and from JSON

Python object class example: thing.py

class Thing(object):
    def __init__(self, name):
        self.name = name

Client call rpc with a python object: client-test.py

import asyncio
from async4jsonrpc.client import JsonRpcClient
from tests.thing import Thing

# create RPC json client
client = JsonRpcClient('127.0.0.1', 8080)

async def call_object_rpc():
    obj = Thing('Awesome')
    r = await client.ping(obj)
    print(r)

asyncio.run(call_object_rpc())
