I'm building a microservice in Ktor. While we are working within the application module, Ktor provides access to the call object which contains authorization data.

My problem is that I need to access the call object from a service-level class. In Spring, you would do this by accessing the SecurityContext which is globally available via a ThreadLocal. Ktor, being coroutine-driven, does not have that option.

Do I really need to pass down the call object through my service layer methods, or is there a way in Ktor to have some sort of "call context" object that you can access from anywhere?

  It may be worth mentioning that coroutines do have a CoroutineContext which is basically just a map.

  The problem with CoroutineContext is that it is easy to lose it along the way (e.g. when calling async). In all those places, the coroutine context must be passed along explicitly, which is easy to forget (the compiler won't complain). But I do agree, with some discipline, this is a solution.
