extractLog

Signature

def extractLog: Directive1[LoggingAdapter]

Description

Extracts a LoggingAdapter from the request context which can be used for logging inside the route.

The extractLog directive is used for providing logging to routes, such that they don’t have to depend on closing over a logger provided in the class body.

See extract and Providing Values to Inner Routes for an overview of similar directives.

Example

val route =
  extractLog { log =>
    log.debug("I'm logging things in much detail..!")
    complete("It's amazing!")
  }

// tests:
Get("/abcdef") ~> route ~> check {
  responseAs[String] shouldEqual "It's amazing!"
}
