Class ResourceFixupRenderer

java.lang.Object

org.esigate.renderers.ResourceFixupRenderer

All Implemented Interfaces:

Renderer

public class ResourceFixupRenderer
extends Object
implements Renderer

This renderer "fixes" links to resources, images and pages in pages retrieved by esigate :

• Current-path-relative urls are converted to full path relative urls ( img/test.img -> /myapp/curentpath/img/test.img)
• All relative urls can be converted to absolute urls (including server name)

This enables use of esigate without any special modifications of the generated urls on the provider side. All href and src attributes are processed, except javascript links.

Constructor Detail

ResourceFixupRenderer

public ResourceFixupRenderer(String baseUrl,
                             String requestUrl,
                             UrlRewriter urlRewriter,
                             String visibleBaseUrl,
                             boolean absolute)

Creates a renderer which fixes urls. The domain name and the url path are computed from the full url made of baseUrl + pageFullPath. If mode is ABSOLUTE, all relative urls will be replaced by the full urls :

• images/image.png is replaced by http://server/context/images/image.png
• /context/images/image.png is replaced by http://server/context/images/image.png

If mode is RELATIVE, context will be added to relative urls :

• images/image.png is replaced by /context/images/image.png

Parameters:

baseUrl - Base url (same as configured in provider).

requestUrl - Page as used in tag lib or using API

urlRewriter - The url rewriter for this provider

visibleBaseUrl - The base url as seen from the client

absolute - Should the rewritten urls contain the scheme host and port
