|

// presented in AuthValues (the client hands out photon_access_token via RoomController's

// /Room_server/photon_access_token endpoint - see Createphotonacesstoken in ClientSecurity).

// We validate it as our own JWT, and echo back the real account id as the Photon UserId -

// which the client CANNOT forge at the Photon protocol level (matches the pattern the 2023
|
|
// Campus-Server used, see PhotonAuthController.cs there).

|
|
// Contract: reply 200 with JSON { ResultCode, UserId, Nickname }.

|
// ResultCode 1 = authenticated, 2 = failed / unauthorized, 3 = required params missing.
|
|
// If custom auth isn't configured on the Photon apps this endpoint just never gets called -
|
|
// it costs nothing to ship, and makes the server ready the moment custom auth is turned on.
