Playing JSONP

Basic example to integrate JSONP mechanism in Play Application with the help of play-jsonp-filter module

play-jsonp-filter

This filter enables JSONP on your existing API: any resource that returns a JSON content will return a JavaScript fragment if there is an additional callback parameter in the query string.

For example, if the resource /foo gives the following JSON result: {"foo": "bar"}, the resource /foo?callback=f will give the following JavaScript result: f({"foo": "bar"});.

Dependency

The play-jsonp-filter module is distributed using Maven Central so it can be easily added as a library dependency in your Play Application’s SBT build scripts, as follows:

"org.julienrf"      %% "play-jsonp-filter"      % "1.2"

Usage

Add the julienrf.play.jsonp.Jsonp filter to your Global object:

import play.api.mvc.WithFilters
import play.api.libs.concurrent.Execution.Implicits.defaultContext
import julienrf.play.jsonp.Jsonp

object Global extends WithFilters(new Jsonp)
