cors - play.filters.cors

1. trait CORSActionBuilder extends ActionBuilder[Request] with AbstractCORSPolicy

   An play.api.mvc.ActionBuilder that implements Cross-Origin Resource Sharing (CORS)

2. trait CORSComponents extends AnyRef

   Components for the CORS Filter

3. case class CORSConfig(allowedOrigins: Origins = Origins.None, isHttpMethodAllowed: (String) ⇒ Boolean = _ => true, isHttpHeaderAllowed: (String) ⇒ Boolean = _ => true, exposedHeaders: Seq[String] = Seq.empty, supportsCredentials: Boolean = true, preflightMaxAge: Duration = 1.hour, serveForbiddenOrigins: Boolean = false) extends Product with Serializable

   Configuration for AbstractCORSPolicy

   Configuration for AbstractCORSPolicy

   • allow only requests with origins from a whitelist (by default all origins are allowed)
   • allow only HTTP methods from a whitelist for preflight requests (by default all methods are allowed)
   • allow only HTTP headers from a whitelist for preflight requests (by default all headers are allowed)
   • set custom HTTP headers to be exposed in the response (by default no headers are exposed)
   • disable/enable support for credentials (by default credentials support is enabled)
   • set how long (in seconds) the results of a preflight request can be cached in a preflight result cache (by default 3600 seconds, 1 hour)
   • enable/disable serving requests with origins not in whitelist as non-CORS requests (by default they are forbidden)

   allowedOrigins

   §6.1.2 §6.2.2 Always matching is acceptable since the list of origins can be unbounded.

   isHttpMethodAllowed

   §6.2.5 Always matching is acceptable since the list of methods can be unbounded.

   isHttpHeaderAllowed

   §6.2.6 Always matching is acceptable since the list of headers can be unbounded.

4. class CORSConfigProvider extends Provider[CORSConfig]

   Provider for CORSConfig.

5. class CORSFilter extends Filter with AbstractCORSPolicy

   A play.api.mvc.Filter that implements Cross-Origin Resource Sharing (CORS)

   A play.api.mvc.Filter that implements Cross-Origin Resource Sharing (CORS)

   It can be configured to...

   • filter paths by a whitelist of path prefixes
   • allow only requests with origins from a whitelist (by default all origins are allowed)
   • allow only HTTP methods from a whitelist for preflight requests (by default all methods are allowed)
   • allow only HTTP headers from a whitelist for preflight requests (by default all headers are allowed)
   • set custom HTTP headers to be exposed in the response (by default no headers are exposed)
   • disable/enable support for credentials (by default credentials support is enabled)
   • set how long (in seconds) the results of a preflight request can be cached in a preflight result cache (by default 3600 seconds, 1 hour)

1. object CORSActionBuilder

   An play.api.mvc.ActionBuilder that implements Cross-Origin Resource Sharing (CORS)

   An play.api.mvc.ActionBuilder that implements Cross-Origin Resource Sharing (CORS)

   It can be configured to...

   • allow only requests with origins from a whitelist (by default all origins are allowed)
   • allow only HTTP methods from a whitelist for preflight requests (by default all methods are allowed)
   • allow only HTTP headers from a whitelist for preflight requests (by default all headers are allowed)
   • set custom HTTP headers to be exposed in the response (by default no headers are exposed)
   • disable/enable support for credentials (by default credentials support is enabled)
   • set how long (in seconds) the results of a preflight request can be cached in a preflight result cache (by default 3600 seconds, 1 hour)

   Example:

   1. CORSActionBuilder(configuration) { Ok } // an action that uses the application configuration
      CORSActionBuilder(configuration, "my-conf-path") { Ok } // an action that uses a subtree of the application configuration
      val corsConfig: CORSConfig = ...
      CORSActionBuilder(conf) { Ok } // an action that uses a locally defined configuration
