Pyro：是否可以将类从服务器传递到客户端，然后在客户端实例化该类的实例？

Question

High level overview: I have a server.py file and a class WorkTask.py that has some function execute in it, both stored on my server. I also have a client.py that runs remotely and connects to the server using pyro. Is there anyway that I can pass the WorkTask class from the server to the client and then run the WorkTask.execute() function on the client side?

Answer 1

Only if you have a copy of WorkTask.py on the client already, and are using the pickle serializer.

You could also perhaps look at Pyro4.utils.flame.createModule(). See https://pythonhosted.org/Pyro4/flame.html

It's a big security risk though because using pickle allows for arbitrary code execution if you connect to an untrusted remote party.
