Define a set of extractors allowing to pattern match on the Accept HTTP header of a request
Convenient class to generate extractors checking if a given mime type matches the Accept header of a request.
Convenient class to generate extractors checking if a given mime type matches the Accept header of a request. Example of use:
val AcceptsMp3 = Accepting("audio/mp3")
Then:
request match { case AcceptsMp3() => ... }
An action is essentially a (Request[A] => Result) function that handles a request and generates a result to be sent to the client.
An action is essentially a (Request[A] => Result) function that handles a request and generates a result to be sent to the client.
For example,
val echo = Action { request => Ok("Got request [" + request + "]") }

Provides helpers for creating Action values.
A simple kind of ActionRefiner which, given a request (of type R), may either immediately produce a Result (for example, an error), or continue its Action block with the same request.
A simple kind of ActionRefiner which, given a request (of type R), may either immediately produce a Result (for example, an error), or continue its Action block with the same request. The critical (abstract) function is filter.
A builder for generic Actions that generalizes over the type of requests.
A builder for generic Actions that generalizes over the type of requests. An ActionFunction[R,P] may be chained onto an existing ActionBuilder[R] to produce a new ActionBuilder[P] using andThen. The critical (abstract) function is invokeBlock. Most users will want to use ActionBuilder instead.
the type of the request on which this is invoked (input)
the parameter type which blocks executed by this builder take (output)
A simple kind of ActionFunction which, given a request (of type R), may either immediately produce a Result (for example, an error), or call its Action block with a parameter (of type P).
A simple kind of ActionFunction which, given a request (of type R), may either immediately produce a Result (for example, an error), or call its Action block with a parameter (of type P). The critical (abstract) function is refine.
A simple kind of ActionRefiner which, given a request (of type R), unconditionally transforms it to a new parameter type (P) to be passed to its Action block.
A simple kind of ActionRefiner which, given a request (of type R), unconditionally transforms it to a new parameter type (P) to be passed to its Action block. The critical (abstract) function is transform.

An HTTP cookie.
An HTTP cookie.
the cookie name
the cookie value
the cookie expiration date in seconds, None for a transient cookie, or a value less than 0 to expire a cookie now
the cookie path, defaulting to the root path /
the cookie domain
whether this cookie is secured, sent only for HTTPS requests
whether this cookie is HTTP only, i.e. not accessible from client-side JavaScipt code
Trait that should be extended by the Cookie helpers.
The HTTP cookies set.
A cookie to be discarded.
A cookie to be discarded. This contains only the data necessary for discarding a cookie.
the name of the cookie to discard
the path of the cookie, defaults to the root path

An EssentialAction underlies every Action.
An EssentialAction underlies every Action. Given a RequestHeader, an
EssentialAction consumes the request body (an ByteString) and returns
a Result.
An EssentialAction is a Handler, which means it is one of the objects
that Play uses to handle requests.
Implement this interface if you want to add a Filter to your application
Implement this interface if you want to add a Filter to your application
object AccessLog extends Filter { override def apply(next: RequestHeader => Future[Result])(request: RequestHeader): Future[Result] = { val result = next(request) result.map { r => play.Logger.info(request + "\n\t => " + r; r } } }
HTTP Flash scope.
HTTP Flash scope.
Flash data are encoded into an HTTP cookie, and can only contain simple String values.
An Handler handles a request.
An Handler handles a request. Play understands several types of handlers,
for example EssentialActions and WebSockets.
The Handler used to handle the request is controlled by GlobalSettings's
onRequestReceived method. The default implementation of
onRequestReceived delegates to onRouteRequest which calls the default
Router.
The HTTP headers set.

Signal a max content size exceeded.

Multipart form data body.
Binder for URL path parameters.
Binder for URL path parameters.
You can provide an implementation of PathBindable[A] for any type A you want to be able to
bind directly from the request path.
For example, given this class definition:
case class User(id: Int, name: String, age: Int)
You can define a binder retrieving a User instance from its id, useable like the following:
// In your routes: // GET /show/:user controllers.Application.show(user) // For example: /show/42 object Application extends Controller { def show(user: User) = Action { ... } }
The definition of binder can look like the following:
object User { implicit def pathBinder(implicit intBinder: PathBindable[Int]) = new PathBindable[User] { override def bind(key: String, value: String): Either[String, User] = { for { id <- intBinder.bind(key, value).right user <- User.findById(id).toRight("User not found").right } yield user } override def unbind(key: String, user: User): String = { intBinder.unbind(key, user.id) } } }
Binder for query string parameters.
Binder for query string parameters.
You can provide an implementation of QueryStringBindable[A] for any type A you want to be able to
bind directly from the request query string.
For example, if you have the following type to encode pagination:
/** * @param index Current page index * @param size Number of items in a page */ case class Pager(index: Int, size: Int)
Play will create a Pager(5, 42) value from a query string looking like /foo?p.index=5&p.size=42 if you define
an instance of QueryStringBindable[Pager] available in the implicit scope.
For example:
object Pager { implicit def queryStringBinder(implicit intBinder: QueryStringBindable[Int]) = new QueryStringBindable[Pager] { override def bind(key: String, params: Map[String, Seq[String]]): Option[Either[String, Pager]] = { for { index <- intBinder.bind(key + ".index", params) size <- intBinder.bind(key + ".size", params) } yield { (index, size) match { case (Right(index), Right(size)) => Right(Pager(index, size)) case _ => Left("Unable to bind a Pager") } } } override def unbind(key: String, pager: Pager): String = { intBinder.unbind(key + ".index", pager.index) + "&" + intBinder.unbind(key + ".size", pager.size) } } }
To use it in a route, just write a type annotation aside the parameter you want to bind:
GET /foo controllers.foo(p: Pager)
