akka-http

I'm trying out Akka-http and hopefully someone can shed light on a the following questions: How does one create different routes based on the accept: header in the request? For example, i want one code path to handle "json" and one to handle "xml" requests (with default to "json" if header is missing) In cases where I don't want the contentType to be inferred, how do i specify it? For example, in the code below I try to run the json through compactPrint() but this changes it to a string, hence "text/plain". I want to override that and tell the client it's still json. My code is something like

I'm trying to write a tool for batch data upload using Akka HTTP 2.0-M2. But I'm facing akka.stream.OverflowStrategy$Fail$BufferOverflowException: Exceeded configured max-open-requests value of [32] error. I tried to isolate a problem and here is the sample code which also fails: public class TestMaxRequests { private static final class Router extends HttpApp { @Override public Route createRoute() { return route( path("test").route( get(handleWith(ctx -> ctx.complete("OK"))) ) ); } } public static void main(String[] args) { ActorSystem actorSystem = ActorSystem.create(); Materializer

使用Akka-Http构建REST风格的微服务，服务API应尽量遵循REST语义，数据使用JSON格式交互。在有错误发生时应返回： {"errcode":409,"errmsg":"aa is invalid，the ID is expected to be bb"} 类似的JSON错误消息。 代码： https://github.com/yangbajing/akka-action http://git.oschina.net/yangbajing/akka-action 代码 首先来看看代码文件结构： ├── ApiRoute.scala ├── App.scala ├── ContextProps.scala ├── book │ ├── Book.scala │ ├── BookContextProps.scala │ ├── BookRoute.scala │ └── BookService.scala └── news ├── News.scala ├── NewsContextProps.scala ├── NewsRoute.scala └── NewsService.scala 通过名字可以看出， App.scala 是启动程序，以 Route 结尾的是API路由定义文件， Service 结尾的就是服务实现代码了。 ContextProps

I would like to create a Source and later push elements on it, like in: val src = ... // create the Source here // and then, do something like this pushElement(x1, src) pushElement(x2, src) What is the recommended way to do this? Thanks! There are three ways this can be achieved: 1. Post Materialization with SourceQueue You can use Source.queue that materializes the Flow into a SourceQueue : case class Weather(zipCode : String, temperature : Double, raining : Boolean) val bufferSize = 100 //if the buffer fills up then this strategy drops the oldest elements //upon the arrival of a new element.
