flaskJSONRPCServer resides on github. You can file issues or pull requests there.


How to install


Simple example





pip install flaskJSONRPCServer


Simple server. More examples you can find in directory example/

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

   # Return client's IP
