The first example we'll look at is the first simple implementation of our API. We won't be returning real objects or JSON yet, but a couple of strings. The code for this step looks like this:
val route =
// handle the /tasks part of the request
path("tasks") {
get {
complete { "Return all the tasks" }
} ~
post {
complete { s"Create a new task" }
} // any other request is also rejected.
} ~ { // we handle the "/tasks/id separately"
path("tasks" / IntNumber) {
task => {
entity(as[String]) { body => {
put { complete {
s"Update an existing task with id: $task and body: $body" } }
} ~
get { complete {
s"Get an existing task with id : $task and body: $body" } }
} ~ {
// We can manually add this rejection.
reject(MethodRejection(HttpMethods.GET),
MethodRejection(HttpMethods.PUT...
