pyRpc 0.1

pyRpc is a simple remote procedure call Python module using ZeroMQ.

Remote Procedure Call support, for exposing local function as public services, and calling public services on remote applications.

Wraps around ZeroMQ for messaging. http://www.zeromq.org/

This is a very basic module that allows you to create an application which exports various functions as services, and then to have client apps call these services almost like a native python call.

Install

Download and:

python setup.py install

or

 pip install pyRpc

or

 easy_install pyRpc

Basic Example

Exporting functions as services (server)

import time
from pyRpc import PyRpc

def add(a, b):
 """ Returns a + b """
 return a+b

def favoriteColor():
 """ Tell you our favorite color """
 return "red"

myRpc = PyRpc("com.myCompany.MyApplication")
time.sleep(.1)

myRpc.publishService(add)
myRpc.publishService(favoriteColor)
myRpc.start()

try:
 while True:
 time.sleep(1)

except KeyboardInterrupt:
 myRpc.stop()

Calling remote services from a client

import time
from pyRpc import RpcConnection

def response(resp):
 print "Got response:", resp
 print "1 + 2 =", resp.result
 
remote = RpcConnection("com.myCompany.MyApplication")
time.sleep(.1)

resp = remote.availableServices()
for service in resp.result:
 print "\nService: %(service)s \nDescription: %(doc)s \nUsage: %(format)s\n" % service


# calls remove add() and does not wait. Result will be returned to response()
remote.call("add", args=(1, 2), callback=response)

# blocks while waiting for a response
resp = remote.call("favoriteColor")
print "Favorite color:", resp.result

time.sleep(1)

remote.close()

time.sleep(1)
