flaskJSONRPCServer
==================
This library is an extended implementation of server for JSON-RPC
protocol. It supports only json-rpc 2.0 specification for now, which
includes batch submission, keyword arguments, notifications, etc.
Comments, bug reports
~~~~~~~~~~~~~~~~~~~~~
flaskJSONRPCServer resides on **github**. You can file issues or pull
requests `there <https://github.com/byaka/flaskJSONRPCServer/issues>`__.
Requirements
~~~~~~~~~~~~
- **Python2.6** or **Python2.7**
- **Flask** >= 0.10 (not tested with older version)
- **Gevent** >= 1.0 (optionally, but recommended)

Pros
~~~~
- Lib ready for **production**, we use it in some products
- Lib tested over **"highload"** (over 60 connections per second, 24/7
and it's not simulation) with **Gevent** enabled and no stability
issues or memory leak (this is why i'm wrote this library)
- Auto **CORS**
- Simple switching to **Gevent** as backend
- Auto fallback to **JSONP** on GET requests (for old browsers, that
don't support CORS like **IE**\ <10)
- Dispatchers can simply get info about connection (**IP**,
**Cookies**, **Headers**)
- Dispatchers can simply set **Cookies**, change output **Headers**,
change output format for **JSONP** requests
- Lib fully support **Notification** requests (see *example/notify.py*)
- Lib supports **restarting** server (see *example/restart.py*)
- Lib supports **hot-reloading** of API (see *example/hotReload1.py*,
*example/hotReload2.py*)
- Lib supports **multiple servers** in one app (see
*example/multiple.py*)
- Lib supports **merging** with another WSGI app on the same IP:PORT
(see *example/mergeFlaskApp.py*)
- Lib supports different **execution-backends**, for example
multiprocessing (see *example/parallelExecuting.py*)
- Lib supports **locking** (you can lock all server or specific
dispatchers)
- Lib supports different **serializing-backends** so you can implement
any protocol, not only JSON
- Lib supports **individual settings** for different dispatchers. For
example one of them can be processed with parallel (multiprocess)
backend, other with standard processing
- Lib collects self **speed-stats**
Cons
~~~~
- Not fully **documentated**. For now only examples in package and `API
documentation <https://byaka.github.io/flaskJSONRPCServer-docs/>`__.
- Lib not has **decorators**, so it not a "Flask-way" (this can be
simply added, but i not use decorators, sorry)
- Lib not covered with **tests**.
Install
~~~~~~~
``pip install flaskJSONRPCServer``
Examples
~~~~~~~~
Simple server. More examples you can find in directory *example/*
.. code:: python
import sys, time, random
from flaskJSONRPCServer import flaskJSONRPCServer
class mySharedMethods:
def random(self):
# Sipmly return random value (0..mult)
return int(random.random()*65536)
class mySharedMethods2:
def random(self):
# Sipmly return random value (0..mult)
return round(random.random()*1, 1)
def echo(data='Hello world!'):
# Simply echo
return data
echo._alias='helloworld' #setting alias for method
def myip(_connection=None):
# Return client's IP
return 'Hello, %s!'%(_connection.ip)
def setcookie(_connection=None):
# Set cookie to client
print _connection.cookies
_connection.cookiesOut.append({'name':'myTestCookie', 'value':'Your IP is %s'%_connection.ip, 'domain':'byaka.name'})
return 'Setted'
def stats(_connection=None):
#return server's speed stats
return _connection.server.stats(inMS=True) #inMS=True return stats in milliseconds
def big(_connection=None):
_connection.allowCompress=True #allow compression for this method only
s="""
... large data here ...
"""
return s
big._alias=['bigdata', 'compressed'] #setting alias for method
if __name__=='__main__':
print 'Running api..'
# Creating instance of server
# <blocking> switch server to sync mode when <gevent> is False
# <cors> switch auto CORS support
# <gevent> switch to using Gevent as backend
# <debug> switch to logging connection's info from Flask
# <log> switch to logging debug info from flaskJSONRPCServer
# <fallback> switch auto fallback to JSONP on GET requests
# <allowCompress> switch auto compression
# <compressMinSize> set min limit for compression
# <tweakDescriptors> set descriptor's limit for server
# <jsonBackend> set JSON backend. Auto fallback to native when problems
# <notifBackend> set backend for Notify-requests
server=flaskJSONRPCServer(("0.0.0.0", 7001), blocking=False, cors=True, gevent=True, debug=False, log=False, fallback=True, allowCompress=False, jsonBackend='simplejson', notifBackend='simple', tweakDescriptors=[1000, 1000])
# Register dispatcher for all methods of instance
server.registerInstance(mySharedMethods(), path='/api')
# same name, but another path
server.registerInstance(mySharedMethods2(), path='/api2')
# Register dispatchers for single functions
server.registerFunction(setcookie, path='/api')
server.registerFunction(echo, path='/api')
server.registerFunction(myip, path='/api')
server.registerFunction(big, path='/api')
server.registerFunction(stats, path='/api')
# Run server
server.serveForever()
# Now you can access this api by path http://127.0.0.1:7001/api for JSON-RPC requests
# Or by path http://127.0.0.1:7001/api/<method>?jsonp=<callback>&(params) for JSONP requests
# For example by http://127.0.0.1:7001/api/echo?data=test_data&jsonp=jsonpCallback_129620
