I have implemented a rpyc sharing server which has an initialized
class object and clients will access this shared object. I am able to
access this object if i connect directly but if i use function for
connecting to server and return the object i am getting error. Below
is the code
**Server**
===========
import rpyc
class SharedClass(object):
def __init__(self,string):
print string
def action(self):
print 'i am doing something'
s=SharedClass('hi')
class MyService(rpyc.Service):
def on_connect(self):
pass
def on_disconnect(self):
pass
def exposed_get_shared(self): # this is an exposed method
return s
if __name__=='__main__':
from rpyc.utils.server import ThreadedServer
t=ThreadedServer(MyService,port=18861,protocol_config={"allow_public_attrs":True})
t.start()
At the client side if i try to connect directly it is working, whereas
when i try to make connection inside a function and return the object
i am getting an error
**Client**
**Direct connection**

**Using a function**
If i try to do it in a function, i am getting an error ;(
