问题 I have following action def login: Result = Action(parse.json) { request => if (/* Let's we say here is some validation */) { return BadRequest("bad") } Ok("all ok") } This is giving me an Error. Intellij is suggesting Action[JsValue] type. When I say return will be of that type, I am getting again error on BadRequest line, because types doesn't match. I tried searching about this problem, and I found some answers which are suggesting to set Action[AnyContent] as return type. But I am STILL

问题 I know how to do json parsing using play json library for play application. For example I have following code: class PersonController extends Controller { case class Person(age: Int, name: String) implicit val personReads = Json.reads[Person] implicit val personWrites = Json.writes[Person] def create = Action(parse.json) { implicit request => rs.body.validate[Person] match { case s: JsSuccess => ... case e: JsError => ... } } } How should I write the code like Reads and Writes using Argonaut

问题 I'm having a bit of trouble understanding the basic idea of dependency injection. (I'm using Play 2.5 with the play-slick module) Say I have a class Users that needs a database connection. package models @Singleton class Users @Inject() (dbConfigProvider: DatabaseConfigProvider) { private val db = dbConfigProvider.get[JdbcProfile].db private val users = TableQuery[UserTable] private val setupAction = DBIO.seq(users.schema.create) private val setupFuture: Future[Unit] = db.run(setupAction) def

问题 Is the scenario below possible? A warning that I understand DNS only in its basic form. We have an API (built using Play) that we would like to make available via a an address say http://api.publicname.com However, we would like to split this API in 2 Play projects (e.g. myapione and myapitwo). Then access them using only 1 domain but two separate "subfolders" So I have been looking for the possibility of mapping say... http://myinternal.domain:9000 to http://api.publicname.com/myapione ...

问题 I'm working on a play application that uses WS to make an asynchronous call to an external api and I can't figure out why I'm losing unicode chars when consuming for instance if they api is producing something like: { "title": "Plück, Franke" } and make a call to the api with: ws.url("http://example.org/stuff/").get().map { response => println(response.body) Ok.... The following will print: { "title":"Plück, Franke" } I'm trying to find if there is a header argument that I need to be passing

问题 I have an existing Scala play application which has a REST API that calls another external REST API. I want to mock the external Web service returning fake JSON data for internal tests. Based on example from: https://www.playframework.com/documentation/2.6.x/ScalaTestingWebServiceClients I followed example exactly as in Documentation and I'm getting compiler errors due to deprecated class Action. import play.core.server.Server import play.api.routing.sird._ import play.api.mvc._ import play

问题 I have the following url : http://localhost/api/books/?bookId=21&bookId=62?authorId=2 I want to retrieve all the bookId values with Scala and then use Squeryl to do a fetch in a the database. I'm using the PlayFrameWork as the WebServer, so here's my code : val params = request.queryString.map { case (k, v) => k -> v(0) } // Retrieve only one the first occurence of a param So params.get("bookId") will only get the last value in the bookId params. e-g : 62 .
