[Jsonrpc-cpp-devel] Knowing who sent the request.

[Elestedt, F. <fr...@el...>]

Hi,

I'm looking to use jsonrcp-cpp over websockets. The websocket parts is
solved by websocketpp,
but I now face a "problem" with jsonrcp-cpp and was wondering what you
would think would be the
best solution for me.

What I'm doing is a server where a server can login, and is logged in until
socket disconnect.
Upon connection an event is to be fired on the server, possibly sending
multiple notification messages
to the client.
So my implementation is a two-way rpc - not just client -> server with
responses.

I have the client-side all worked out - it is after all much simpler since
there is only one server.

My problem is that the CallbackMethod does not know from where a message
came.
So I need to pass this information to the CallbackMethid in some manner.

I have two possible suggestions, I've considered both and am looking for
something which might
be possible to incorporate in the mainline release, and not just a for-me
hack...
1. Have the client send the username with each request. The entire request
is passed to the callback, so a centralized list of all logged in users
would allow the CallbackMethod to make a lookup on the connection to send
messages.
2. Add templates to jsonrpc-cpp. Make the callback function take three
arguments, one of which is a generic class which would be an application
specific connection id container.

Any suggestions?

Thanks
