Hi,
I’m using the C++ API for making a multiplayer simple client for a game developed in Unity. This client is just for connecting to matches and basically being a development time “bot”. The API works fine and I can connect, seek matches, join matches etc. Now I need to run a few RPC calls to get some data from the server. The one RPC call that I tried so far works kinda ok, but the response is missing important data. My code is like below:
NClientPtr client;
NSessionPtr session;
...
client->rpc(session, "get_stuff", opt::nullopt, rpcOkCallback, errorCallback);
...
void rpcOkCallback(const NRpc& rpc) {
std::cout << "RPC data received" << std::endl;
std::cout << " id: " << rpc.id << std::endl;
std::cout << " payload: " << rpc.payload << std::endl;
std::cout << " HTTP key: " << rpc.httpKey << std::endl;
}
This gives me:
RPC data received
id:
payload: <correct JSON data>
HTTP key:
The payload contains what it should, but the id and httpKey fields are always empty. I would assume that id should be get_stuff in this case. I also can’t really find any docs at all that would explain what values they can have, but the NRpc struct implies that all fields should always be populated:
/// Execute an Lua function on the server.
struct NAKAMA_API NRpc
{
std::string id; ///< The identifier of the function.
std::string payload; ///< The payload of the function which must be a JSON object.
std::string httpKey; ///< The authentication key used when executed as a non-client HTTP request.
};
It’s in our case a Go function, but I assume the mention of Lua in the comment is just bit rot.
So, should the id be filled in or do I need to keep track of what RPC call I’m currently executing.
