simplejsonrpc

Simple JSON-RPC 2.0 compilant middleware for python using decorators. With just a few lines of code you get a JSONRPC 2.0 compilant web API running and ready for your needs!

Install

Just install it though pip:

pip install simplejsonrpc

Usage

Just create a service class to store your API calls and decorate your methods:

from simplejsonrpc import *

loginservice = SimpleJSONRPCService(api_version=1)

@jsonremote(loginservice, name='login', doc='Method used to log a user in')
def login(request, user_name, user_pass):
    (...)

More complex example interating it into Web.py!

import web
        
urls = (
    '/', 'index'
    , '/api/', 'json_handler'
    , '/api', 'json_handler'
)
app = web.application(urls, globals())

api_service = SimpleJSONRPCService(api_version=1)

class index:        
    def GET(self, name):
        if not name: 
            name = 'World'
        return 'Hello, ' + name + '!'

class json_handler:        
    def POST(self):
        return api_service(web.webapi.data())

@jsonremote(api_service, doc='print api documentation')
def api(request):
    return api_service.api()
    
@jsonremote(api_service, doc='ping server')
def ping(request):
    return "pong"

if __name__ == "__main__":
    app.run()

Adding API versioning to the previous example

import web
        
urls = (
    '/', 'index'
    , '/api/1/', 'json_handler_v1'
    , '/api/1', 'json_handler_v1'
    , '/api/2/', 'json_handler_v2'
    , '/api/2', 'json_handler_v2'
)
app = web.application(urls, globals())

api_service_v1 = SimpleJSONRPCService(api_version=1)
api_service_v2 = SimpleJSONRPCService(api_version=2)

class index:        
    def GET(self, name):
        if not name: 
            name = 'World'
        return 'Hello, ' + name + '!'

class json_handler_v1:        
    def POST(self):
        return api_service_v1(web.webapi.data())

class json_handler_v1:        
    def POST(self):
        return api_service_v2(web.webapi.data())

@jsonremote(api_service_v1, doc='print api documentation')
def api(request):
    return api_service_v1.api()

@jsonremote(api_service_v1, doc='ping server')
def ping(request):
    return "pong"

@jsonremote(api_service_v2, name='api', doc='print api documentation')
def api_v2(request):
    return api_service_v2.api()

@jsonremote(api_service_v2, name='ping', doc='ping server')
def ping_v2(request):
    return "pong"

if __name__ == "__main__":
    app.run()
