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
-------------

* Python 3.5 & 3.6 compatible
* 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.) <https://aiohttp.readthedocs.io/en/stable/client_reference.html#aiohttp.ClientSession>`_ If not passed to Server, a ClientSession object will be created automatically.

Execute remote JSON-RPC functions

.. code-block:: python

import asyncio
from jsonrpc_async import Server

async def routine():
server = Server('http://localhost:8080')
try:
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)
finally:
await server.session.close()

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

A notification

.. code-block:: python

import asyncio
from jsonrpc_async import Server

async def routine():
server = Server('http://localhost:8080')
try:
await server.foo(bar=1, _notification=True)
finally:
await server.session.close()

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

Pass through arguments to aiohttp (see also `aiohttp documentation <http://aiohttp.readthedocs.io/en/stable/client_reference.html#aiohttp.ClientSession.request>`_)

.. code-block:: python

import asyncio
import aiohttp
from jsonrpc_async import Server

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

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

Pass through aiohttp exceptions

.. code-block:: python

import asyncio
import aiohttp
from jsonrpc_async import Server

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

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.
