A JSON-RPC client library for asyncio

Project description

https://img.shields.io/pypi/v/jsonrpc-async.svg https://github.com/emlove/jsonrpc-async/workflows/tests/badge.svg https://coveralls.io/repos/emlove/jsonrpc-async/badge.svg

This is a compact and simple JSON-RPC client implementation for asyncio python code. This code is forked from https://github.com/gciotta/jsonrpc-requests

Main Features

  • Supports nested namespaces (eg. app.users.getUsers())

  • 100% test coverage

Usage

It is recommended to manage the aiohttp ClientSession object externally and pass it to the Server constructor. (See the aiohttp documentation.) If not passed to Server, a ClientSession object will be created automatically.

Execute remote JSON-RPC functions

import asyncio
from jsonrpc_async import Server

async def routine():
    async with Server('http://localhost:8080') as server:
        await server.foo(1, 2)
        await server.foo(bar=1, baz=2)
        await server.foo({'foo': 'bar'})
        await server.foo.bar(baz=1, qux=2)

asyncio.get_event_loop().run_until_complete(routine())

A notification

import asyncio
from jsonrpc_async import Server

async def routine():
    async with Server('http://localhost:8080') as server:
        await server.foo(bar=1, _notification=True)

asyncio.get_event_loop().run_until_complete(routine())

Pass through arguments to aiohttp (see also aiohttp documentation)

import asyncio
import aiohttp
from jsonrpc_async import Server

async def routine():
    async with Server(
        'http://localhost:8080',
        auth=aiohttp.BasicAuth('user', 'pass'),
        headers={'x-test2': 'true'}
    ) as server:
        await server.foo()

asyncio.get_event_loop().run_until_complete(routine())

Pass through aiohttp exceptions

import asyncio
import aiohttp
from jsonrpc_async import Server

async def routine():
    async with Server('http://unknown-host') as server:
        try:
            await server.foo()
        except TransportError as transport_error:
            print(transport_error.args[1]) # this will hold a aiohttp exception instance

asyncio.get_event_loop().run_until_complete(routine())

Tests

Install the Python tox package and run tox, it’ll test this package with various versions of Python.

Changelog

2.1.2 (2023-07-10)

2.1.1 (2022-05-03)

  • Unpin test dependencies

2.1.0 (2021-05-03)

  • Bumped jsonrpc-base to version 2.1.0

2.0.0 (2021-03-16)

  • Bumped jsonrpc-base to version 2.0.0

  • BREAKING CHANGE: Allow single mapping as a positional parameter. Previously, when calling with a single dict as a parameter (example: server.foo({'bar': 0})), the mapping was used as the JSON-RPC keyword parameters. This made it impossible to send a mapping as the first and only positional parameter. If you depended on the old behavior, you can recreate it by spreading the mapping as your method’s kwargs. (example: server.foo(**{'bar': 0}))

1.1.1 (2019-11-12)

  • Bumped jsonrpc-base to version 1.0.3

1.1.0 (2018-09-04)

  • Added support for using a custom json.loads method (#1) @tdivis

1.0.1 (2018-08-23)

  • Bumped jsonrpc-base to version 1.0.2

1.0.0 (2018-07-06)

  • Bumped minimum aiohttp version to 3.0.0

  • Bumped jsonrpc-base to version 1.0.1

Credits

@gciotta for creating the base project jsonrpc-requests.

@mbroadst for providing full support for nested method calls, JSON-RPC RFC compliance and other improvements.

@vaab for providing api and tests improvements, better RFC compliance.
