All Implemented Interfaces:

Heaplet

public class CorsFilterHeaplet
extends GenericHeaplet

A CorsFilterHeaplet configures a CorsFilter in a heap environment.

It will select an applicable CORS policy based on the request's Origin header value.

{
   "type": "CorsFilter",
   "config": {
     "policies"        : list<policy> [REQUIRED - List of CORS policies. ]
     "failureHandler"  : handler      [OPTIONAL - Handler called on failure. ]
   }
 }
 

Each CORS policy is defined as the following:

{
   "acceptedOrigins":  list<url>          [REQUIRED - List of URL for matching Origin (case insensitive).
                       "*"                            Use this literal to accept any origin. ]
   "acceptedMethods":  list<string>       [OPTIONAL - Set of accepted method names (case sensitive).
                       "*"                            Use this literal to accept any methods.
                                                      Defaults to none (no methods are accepted). ]
   "acceptedHeaders":  list<string>       [OPTIONAL - Set of accepted header names (case insensitive).
                       "*"                            Use this literal to accept all headers.
                                                      Defaults to none (no headers are accepted). ]
   "exposedHeaders":   list<string>       [OPTIONAL - List of exposed headers. Defaults to empty list. ]
   "maxAge":           duration           [OPTIONAL - Maximum duration to cache preflight result.
                                                      Defaults to omit header. ]
   "allowCredentials": boolean            [OPTIONAL - Are credentials allowed ? Defaults to false. ]
 }
 

The origins are defined as URLs with nothing else than scheme, hostname and optionally a port number (typically http://www.example.com). If port number is not defined, origins with either no port number or with the default port number (80 for http, 443 for https) are accepted.

Method Details

create

public Object create()
              throws HeapException

Description copied from class: GenericHeaplet

Called to request the heaplet create an object. Called by Heaplet.create(Name, JsonValue, Heap) after initializing the protected field members. Implementations should parse configuration but not acquire resources, start threads, or log any initialization messages. These tasks should be performed by the GenericHeaplet.start() method.

Specified by:

create in class GenericHeaplet

Returns:

The created object.

Throws:

HeapException - if an exception occurred during creation of the heap object or any of its dependencies.
