I have a socket set up between a client and server program. Let's say
that I serialize (pickle) some data in the client and send it to the
server with the intention of calling a function in the server to process
the data. How would one execute the function? This is not for a
web-based application, BTW -- it's a desktop based application
My current thought process is (using a generalized example):
I have a list of numbers in the client and want to find the length of
the list using the server. There exists a function find_len() in the
server code. I have a list of numbers [1,2,3]. On the client side, I
create the tuple ("find_len", [1,2,3]), and serialize it. I pass this
serialized object via a socket to the server, which unpickles it. The
server takes the key (find_len) and uses a getattr call to get the
find_len function. The server then calls find_len([1,2,3]) to get the
sum.
def find_len(list_): return
Are there better ways of accomplishing this (I'm aware that there are
security pitfalls here...)
xmlrpc does more or less the same thing, but serializing in xml instead of
pickling.
