Being able to return errors from a method callback

[adriweb]

Hi,

I'd like to know if, for methods, there's a way to return errors ourselves (for instance, if some specific request content/value isn't valid) instead of just filling the response value (that's fine when everything's as expected)
It's OK for me if I have to write the full response JSON myself, I guess, but my feeling is that we're possibly a bit too limited right now as to what we can access from the method callbacks, unless I missed something.

Thank you!

I totally agree. I thought I implemented exception handling for callbacks, but it appears I didn't.

Actually I did implement. I extended the examples.

Ah, right - but I was talking about methods directly, like here

libjson-rpc-cpp/src/examples/filedescriptorserver.cpp

Lines 56 to 59 in 3ec1ce2

	// method
	void sayHello(const Json::Value &request, Json::Value &response) {
	response = "Hello: " + request["name"].asString();
	}

But I haven't actually tried that yet, maybe it works fine - I'll see in a couple hours...

Edit: works just fine, we can throw it as well, especially with JsonRpcException(int code, const std::string& message, const Json::Value &data) to control all the fields, great!.

Thanks!
