Easy CORS integration for Play:
- use CORS with your Playframework application
- No additional controllers or routes required
Add this to your play build/sbt
libraryDependencies ++= Seq(
"de.knutwalker" %% "cors-play" % "0.1.0"
)
resolvers += "Sonatype snapshots" at "http://oss.sonatype.org/content/repositories/snapshots/"
libraryDependencies ++= Seq(
"de.knutwalker" %% "cors-play" % "0.1.1-SNAPSHOT"
)
You have to mixin the CorsSupport trait into your Global object
import de.knutwalker.play.cors.{ CorsStrategy, CorsSupport }
import play.api.GlobalSettings
object Global extends GlobalSettings with CorsSupport {
override val corsStrategy = CorsStrategy.Everyone
}You can choose different a CorsStrategy to customize the behavior
CorsStrategy |
Behaviour |
|---|---|
Everyone |
Allow every request, event malformed (not CORS) ones |
Origin |
Allow requests with the Origin header set. For valid CORS requests, this is the same as Everyone. |
NoOne |
Do not allow any requests |
Localhost |
Only allow requests from localhost |
Localhost([ports]) |
Only allow requests from localhost that originate from a given list of ports |
Fixed([origins]) |
Provide a fixed set of allowed origins. This results in white-listing behaviour on the browser-side (as the origins are sent as is) |
WhiteList([origins]) |
Provide a white list of origins, that are allow to make a CORS request. The list is resolved on server-side, only the white-listed origin is sent in the header. |
BlackList([origins]) |
Provide a black list of origins, that are not allowed to make CORS requests. The list is resolved on server-side, only the not-black-listed origin is sent in the header. |
Satisfies(handler) |
Define a custom check, that return true for allowed requests, and false otherwise. (Sent origin will be *) |
Satisfies(handler).allowing(origin) |
Define a custom check, that return true for allowed requests, and false otherwise. (Sent origin will be origin) |
Satisfies(handler).withOrigin |
Define a custom check, that return true for allowed requests, and false otherwise. (Sent origin will be the value from the Origin header) |
CustomPF(handler) |
Define a custom check as a partial function, that will match and return an origin for allowed requests, and won't match otherwise |
Custom(handler) |
Define a custom check, that will return Some(origin) for allowed requests, and None otherwise. |
