Is it possible to retrieve Client information in case of multiple clients at the server side?

[vk-gst]

I have an application that contains multiple clients(proxies) interacting with server application. They have a common object path for now.

I wanted to know if it's possible to retrieve the client or proxy instance information(for eg. client-ids) at the server side, so as to associate the requests made by client1, client2, etc.
One way, I could think of is to have unique object paths for each client instance and use this at the server side. But is there any other way with sdbus-c++ that provides me this information?

@vk-gst Yes, a D-Bus message carries a sender field, which you can query through Message::getSender(). According to D-Bus specification, this is a unique name of the sending connection. So with this, you'd able to differentiate clients invoking a server method.

@vk-gst So you simply invoke getSender() on a MethodCall message you get in your server method callback. This message is however only available in basic API level of sdbus-c++. If you use convenience API or generated stub-based API, you don't have access to the underlying message. But this is probably going to be changed soon, I think I will prepare a PR that will make this possible.
