Hi all I am writing a multi-user accounting/business application, which uses sockets to communicate between server and client. The server contains all the business logic. It has no direct knowledge of the client. I have devised a simple message format to exchange information between the two.
At first, I used XML as a message format. Then I read the article that recommended not using XML for Python-to-Python, so I changed it to a pickled collection of Python objects. It works just as well. At present the client uses wxPython. One of my medium-term goals is to write a web-based client. I don't think it will be easy to reproduce all the functionality that I have at present, but I hope to get close. I have not done any serious research yet, but I am pretty sure I will use javascript on the client, to make it as universal as possible. Ideally, the server should be able to handle a wxPython client or a web client, without even knowing which one it is talking to. Obviously I cannot use Pickle for this. So my question is, what is the ideal format to use? I could go back to XML, or I could switch to JSON - I have read a bit about it and it does not seem complicated. My messages are not very large (maximum about 2k so far for a complex screen layout) so I don't think performance will be an issue. I would rather make a decision now, otherwise I will have a lot of changes to make later on. Does anyone have any recommendations?
