I am using RPyC for a client-server application.
I try to change the value of exposed_variable when I call exposed_change() method. I receive "UnboundLocalError: local variable 'exposed_variable' referenced before assignment" error.
However, if I make exposed_variable global (before I try to modify it, like in this example), I get "NameError: name 'exposed_variable' is not defined".
What am I missing?
This is my server:
from rpyc.utils import server
import rpyc
import time
class DoStuffService(rpyc.Service):
exposed_variable = 1
def exposed_change(self):
#global exposed_variable
exposed_variable = exposed_variable + 1
if __name__ == '__main__':
protocol_config = dict(instantiate_custom_exceptions=True, import_custom_exceptions=True)
server.ThreadedServer(DoStuffService, hostname='localhost', port=8888, auto_register=False,protocol_config=protocol_config, backlog=500).start()
This is my client:
import rpyc, sys
import time
def rpyc_call():
conn = rpyc.connect('localhost', 8888)
a = 1
while a:
conn.root.change()
nr=conn.root.variable
print("Nr is ", nr)
time.sleep(10)
if __name__ == '__main__':
rpyc_call()
Thank you. I am wainting for your advice...
