Since by default all http requests coming to a go http server are on their
own goroutine, I am wondering if there is a way to have some sort of
"global" variable that is *local* to a goroutine if that makes sense,
something like this, where "gork" is the namespace for variables available
anywhere within a goroutine:
func PrintLoggedInUser(){
log.Println(gork.loggedInUser)
}
go func(){
var loggedInUser = "abc"
PrintLoggedInUser()
}()
go func(){
var loggedInUser = "def"
PrintLoggedInUser()
}()
why? i am looking to log the current logged in user id, without having to
manually pass that id to every log call.
log.Warn("foo") // will log: "foo", "logged in user id:", abc
log.Error("bar") // will log: "bar", "logged in user id:", abc
but for now, I have to pass the id manually:
log.Warn(id, "foo") // will log: "foo", "logged in user id:", abc
log.Error(id, "bar") // will log: "bar", "logged in user id:", abc
