问题 So I've been trying to use parboiled2 for the last few weeks now, it is possibly the most difficult dependency to add to a build I have come across in my entire life.

问题 Using spray 1.3.2 with akka 2.3.6. (akka is used only for spray). I need to read huge files and for each line make a http request.

问题 I have a specific pipeline in my app that must follow all redirects (let's say up to 50 for sanity's sake), across any domain and protocol (e.g. it could follow http://somewhere.com to https://somewhere.else.com), but only for GET requests. No other pipeline in my app should do this. Here's what it looks like now: val pipeline = sendReceive ~> decode(Gzip) ~> decode(Deflate) ~> unmarshal[String] How can I specify this inside the pipeline's configuration in a host-agnostic manner (i.e. not via

问题 My application has an API using SprayCan. In the application, any blocking code has a separate dispatcher for each specific resource. Is it necessary to protect the API service from being blocked by the application by configuring it with it's own Dispatcher too? Also is it common practice to use a Router for an API service to handle a larger capacity of requests? class MyService extends Actor with HttpService {...} val service = system.actorOf(MyService.props(...).withDispatcher(???)) 回答1: Is

问题 How can I programmatically execute Route of rejection handler and get resulting HttpEntity ? For example assuming that I have RequestContext object and Rejection object I'd like to execute RejectionHandler.default on it and get HttpEntity . Here is example of what I'd like to do: implicit def myRejectionHandler = RejectionHandler.newBuilder() .handleAll[Rejection] { rejections ⇒ def prefixEntity(entity: ResponseEntity): ResponseEntity = entity match { case HttpEntity.Strict(contentType, data)

问题 I have been trying to learn to run a sbt project in docker. I also want to use spray.

问题 I'm new to Scala, and trying to write a little REST API. Here is my route definition : package com.example import akka.actor.Actor import com.example.core.control.CrudController import spray.routing._ class ServiceActor extends Actor with Service { def actorRefFactory = context def receive = runRoute(routes) } trait Service extends HttpService { val crudController = new CrudController() val routes = { path("ads" / IntNumber) { id => get { complete( crudController.getFromElasticSearch(id) ) }
