Cannot add optional parameters to the server method about libjson-rpc-cpp HOT 3 CLOSED

You should be able to register a method that has an object as parameter (e.g. "params" : {"dateFrom": x, "dateTo":y}). In your callback, based in the provided data in the Json::Value& request you can figure out what you need to return. In this case your callback acts more like a facade.

Yes this should work for the most of the cases (when params object exist). The only problem is if the client will omit params object - according to spec he may do it - and then the client will received exception.

I thinked about something like c++ overloading. Server can register multiple methods with the same name but with different parameter list.
Something like

class AbstarctMyStubServer ...
{
public:
AbstarctMyStubServer(...)
{
}

virtual Json::Value GetLog() = 0;
virtual Json::Value GetLog(const std::string &param1 ) = 0;
virtual Json::Value GetLog(const std::string &param1, const std::string &param1) = 0;
...
};

But the problem is that i don't see this is possible with current lib. (may be i'm wrong).

The thing is, that this behavior is not specified in the standard proposal. If you need such things, fork this repo and adapt this as required.
