Class StaticRequestFilter

org.forgerock.openig.filter.StaticRequestFilter

All Implemented Interfaces:

Filter

public final class StaticRequestFilter
extends Object
implements Filter

Creates a new request and send it down the next handler (effectively replacing the previous request). The request can include a form, specified in the form field, which is included in an entity encoded in application/x-www-form-urlencoded format if request method is POST, or otherwise as (additional) query parameters in the URI.

 
 {
      "method"                     : string            [REQUIRED]
      "uri"                        : expression        [REQUIRED]
      "entity"                     : expression        [OPTIONAL - cannot be used simultaneously
                                                                   with a form in POST mode* ]
      "form"                       : object            [OPTIONAL]
      "headers"                    : object            [OPTIONAL]
      "version"                    : string            [OPTIONAL]
 }
 
 

*Note: When method is set to POST, the entity and the form CANNOT be used together in the heaplet because they both determine the request entity. They still can used programmatically together but the form will override any entity content.

Example of use:

 
 {
      "name": "customRequestFilter",
      "type": "StaticRequestFilter",
      "config": {
          "method": "POST",
          "uri": "http://10.10.0.2:8080/wp-login.php",
          "entity": "{\"auth\":{\"passwordCredentials\":
                     {\"username\":\"${attributes.username}\",
                      \"password\":\"${attributes.password}\"}}}"
          "headers": {
              "Warning": [ "199 Miscellaneous warning" ]
          }
      }
 }

Method Details

filter

public Promise<Response,NeverThrowsException> filter(Context context,
 Request request,
 Handler next)

Description copied from interface: Filter

Filters the request and/or response of an exchange. To pass the request to the next filter or handler in the chain, the filter calls next.handle(context, request).

This method may elect not to pass the request to the next filter or handler, and instead handle the request itself. It can achieve this by merely avoiding a call to next.handle(context, request) and creating its own response object. The filter is also at liberty to replace a response with another of its own by intercepting the response returned by the next handler.

Specified by:

filter in interface Filter

Parameters:

context - The request context.

request - The request.

next - The next filter or handler in the chain to handle the request.

Returns:

A Promise representing the response to be returned to the client.
