JSON API realisation
Project description
JSON-RPC2.0 and JSON-RPC1.0 transport specification implementation. Supports python2.6+, python3.2+.
Documentation: http://json-rpc.readthedocs.org
This implementation does not have any transport functionality realization, only protocol. Any client or server realization is easy based on current code, but requires transport libraries, such as requests, gevent or zmq, see examples.
Install
pip install json-rpc
Tests
tox
Quickstart
Server (uses Werkzeug)
from werkzeug.wrappers import Request, Response
from werkzeug.serving import run_simple
from jsonrpc import JSONRPCResponseManager, dispatcher
@dispatcher.add_method
def foobar(**kwargs):
return kwargs["foo"] + kwargs["bar"]
@Request.application
def application(request):
# Dispatcher is dictionary {<method_name>: callable}
dispatcher["echo"] = lambda s: s
dispatcher["add"] = lambda a, b: a + b
response = JSONRPCResponseManager.handle(
request.data, dispatcher)
return Response(response.json, mimetype='application/json')
if __name__ == '__main__':
run_simple('localhost', 4000, application)
Client (uses requests)
import requests
import json
def main():
url = "http://localhost:4000/jsonrpc"
headers = {'content-type': 'application/json'}
# Example echo method
payload = {
"method": "echo",
"params": ["echome!"],
"jsonrpc": "2.0",
"id": 0,
}
response = requests.post(
url, data=json.dumps(payload), headers=headers).json()
assert response["result"] == "echome!"
assert response["jsonrpc"]
assert response["id"] == 0
if __name__ == "__main__":
main()
Competitors
There are several libraries implementing JSON-RPC protocol. List below represents python libraries, none of the supports python3. tinyrpc looks better than others.
