extractRequestContext
Description
Extracts the request’s underlying RequestContext
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
HttpRequest
instance itself.
Example
- Scala
-
source
val route = extractRequestContext { ctx => ctx.log.debug("Using access to additional context available, 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" }
