方法详细资料

setResourceUrlProvider

public void setResourceUrlProvider(@Nullable
 ResourceUrlProvider resourceUrlProvider)

Configure a ResourceUrlProvider to use when resolving the public URL of links in a transformed resource (e.g. import links in a CSS file). This is required only for links expressed as full paths and not for relative links.

getResourceUrlProvider

@Nullable
public ResourceUrlProvider getResourceUrlProvider()

Return the configured ResourceUrlProvider.

resolveUrlPath

@Nullable
protected String resolveUrlPath(String resourcePath,
 RequestContext request,
 cn.taketoday.core.io.Resource resource,
 ResourceTransformerChain transformerChain)

A transformer can use this method when a resource being transformed contains links to other resources. Such links need to be replaced with the public facing link as determined by the resource resolver chain (e.g. the public URL may have a version inserted).

参数:

resourcePath - the path to a resource that needs to be re-written

request - the current request

resource - the resource being transformed

transformerChain - the transformer chain

返回:

the resolved URL, or if not resolvable

toAbsolutePath

protected String toAbsolutePath(String path,
 RequestContext request)

Transform the given relative request path to an absolute path, taking the path of the given request as a point of reference. The resulting path is also cleaned from sequences like "path/..".

参数:

path - the relative path to transform

request - the referer request

返回:

the absolute request path for the given resource path
