JSONP helper.
Example of use, provided the following route definition:
GET /my-service Application.myService(callback: String)
The following action definition:
def myService(callback: String) = Action { val json = ... Ok(Jsonp(callback, json)) }
And the following request:
GET /my-service?callback=foo
The response will have content type "text/javascript" and will look like the following:
foo({...});Another example, showing how to serve either JSON or JSONP from the same action, according to the presence of a "callback" parameter in the query string:
def myService = Action { implicit request => val json = ... request.queryString.get("callback").flatMap(_.headOption) match { case Some(callback) => Ok(Jsonp(callback, json)) case None => Ok(json) } }
