§Description

Extracts the request's underlying RequestContext.

This directive is used as a building block for most of the other directives, which extract the context and by inspecting some of it's values can decide what to do with the request - for example provide a value, or reject the request.

See also extractRequest if only interested in the HttpRequest instance itself.

§Example

val route =
  extractRequestContext { ctx =>
    ctx.log.debug("Using access to additional context availablethings, like the logger.")
    val request = ctx.request
    complete(s"Request method is ${request.method.name} and content-type is ${request.entity.contentType}")
  }
 
// tests:
Post("/", "text") ~> route ~> check {
  responseAs[String] shouldEqual "Request method is POST and content-type is text/plain; charset=UTF-8"
}
Get("/") ~> route ~> check {
  responseAs[String] shouldEqual "Request method is GET and content-type is none/none"
}
