Asynchronous JSON-RPC client for Tornado

Project description

jsonrpc_tornado: a compact asynchronous JSON-RPC client library for `Tornado framework <http://www.tornadoweb.org/>`_
=======================================================================================================

Main Features
-------------

* Python 2.7 & 3.4 compatible
* Exposes tornado.httpclient options
* Non-Blocking I/O
* Supports nested namespaces (eg. `app.users.getUsers()`)

Install
-------
pip install git+https://github.com/artemmus/jsonrpc_tornado.git

Usage
-----
A synchronous example:

.. code-block:: python

from jsonrpc_tornado import JSONRPCServer
from tornado.httpclient import HTTPClient

def fetch(server_url):
server = JSONRPCServer(server_url, http_client=HTTPClient,
request_timeout=5.0)

# call some function on the server
result = server.foo(1, 2)


An example of non-blocking calls:

.. code-block:: python

from jsonrpc_tornado import JSONRPCServer, ProtocolError, TransportError
from tornado import gen

@gen.coroutine
def fetch_coroutine(server_url):
server = JSONRPCServer(server_url, request_timeout=5.0)

try:
# call some function on the server
result = yield server.foo(1, 2)
except ProtocolError as err:
logging.error('Some RPC error %s, %s', err.code, err)
except TransportError as err:
# err.args[1] refers to appropriate HTTPError
logging.error('Transport error %s', err.args[1])


TODO
----

* Tests
