rpcviaredis

Using redis server to build RPC environment - by Oscar LASM

rpcviaredis intended to provide a simple tool for establishing a pattern RPC over an installation Redis. Implement python, it is composed of:

• Server which serve remote commands
• Client Use to connect and call commands hosted on server
• Transport protocol Use to pack and unpack request and response during communication process

Examples:

Server implementation:

from rpcviaredis import *

class DummyServer(ServerRPC):

	def sum(self, x, y):
        return Response(response=x+y, exception=None, reason=None, return_code=200)

    def naive_div(self, x, y):
        return Response(response=x/y, exception=None, reason=None, return_code=200)

    def multiplication(self, x, y):
        return Response(response=x*y, exception=None, reason=None, return_code=200)

if __name__ == "__main__":
    import redis

    r = redis.StrictRedis(db=2)
    s = DummyServer(r, 'test-rpc', transport_klass=JSONTransport)
    try:
        s.start()
    except KeyboardInterrupt:
        pass
    finally:
        s.stop()

Client Implementation

import redis
from rpcviaredis import Client

r = redis.StrictRedis(db=2)
c = Client(r, 'test-rpc', transport_klass=JsonTransport)
retval = c.sum(1,2)
print(retval.response) # print 3
