Flask JSON-RPC

A basic JSON-RPC implementation for your Flask-powered sites based on django-json-rpc.

Some reasons you might want to use:

• Simple, powerful, flexible and pythoic API.
• The Web browseable API.
• Support for authentication.
• Proxy to test your JSON Service.
• Run-time type checking.
• Extensive documentation, and great community support.

For support python 3.3 or later use the branch py3k (experimental).

There is a live example API for testing purposes, available here.

Adding Flask JSON-RPC to your application

1. Installation

$ pip install Flask-JSONRPC

or

$ git clone git://github.com/cenobites/flask-jsonrpc.git
$ cd flask-jsonrpc
$ python setup.py install

2. Getting Started

Create your application and initialize the Flask-JSONRPC.

from flask import Flask
from flask_jsonrpc import JSONRPC

app = Flask(__name__)
jsonrpc = JSONRPC(app, '/api')

Write JSON-RPC methods.

@jsonrpc.method('App.index')
def index():
    return 'Welcome to Flask JSON-RPC'

All code of Example run.py.

3. Running

$ python run.py
 * Running on http://0.0.0.0:5000/

4. Testing

$ curl -i -X POST -d '{"jsonrpc": "2.0", "method": "App.index", "params": {}, "id": "1"}' http://localhost:5000/api
HTTP/1.0 200 OK
Content-Type: application/json
Content-Length: 77
Server: Werkzeug/0.8.3 Python/2.7.3
Date: Fri, 14 Dec 2012 19:26:56 GMT

{
  "jsonrpc": "2.0",
  "id": "1",
  "result": "Welcome to Flask JSON-RPC"
}

Testing your service

You can test your service using the provided web browsable API, available at http://localhost:5000/api/browse (if using the url patterns from above) or with the included ServiceProxy:

>>> from flask_jsonrpc.proxy import ServiceProxy
>>> server = ServiceProxy('http://localhost:5000/api')
>>>
>>> server.App.index()
{'jsonrpc': '2.0', 'id': '91bce374-462f-11e2-af55-f0bf97588c3b', 'result': 'Welcome to Flask JSON-RPC'}

We add the jsonrpc_version variable to the request object. It be either '1.0', '1.1' or '2.0'. Arg.

For more tests see Examples.

Dependecies

• Python (2.6.5+), (2.7, 3.2, 3.3) or later (http://www.python.org)
• Flask 0.9 or later (http://flask.pocoo.org)
