getFromResource

Signature

def getFromResource(resourceName: String)(implicit resolver: ContentTypeResolver): Route 
def getFromResource( resourceName: String, contentType: ContentType, classLoader: ClassLoader 

Description

Completes GET requests with the content of the given classpath resource.

For details refer to getFromFile which works the same way but obtaining the file from the filesystem instead of the applications classpath.

Note that it’s not required to wrap this directive with get as this directive will only respond to GET requests.

Example

Scala
sourceimport org.apache.pekko.http.scaladsl.server.directives._
import ContentTypeResolver.Default

val route =
  path("logs" / Segment) { name =>
    getFromResource(s"$name.log") // uses implicit ContentTypeResolver
  }

// tests:
Get("/logs/example") ~> route ~> check {
  responseAs[String] shouldEqual "example file contents"
}
Java
sourceimport static org.apache.pekko.http.javadsl.server.Directives.getFromResource;
import static org.apache.pekko.http.javadsl.server.Directives.path;

final Route route =
    path(PathMatchers.segment("logs").slash(segment()), name -> getFromResource(name + ".log"));

// tests:
testRoute(route).run(HttpRequest.GET("/logs/example")).assertEntity("example file contents");
