方法详细资料

linkTagAction

public static java.lang.String linkTagAction(java.lang.String target,
                             javax.servlet.ServletRequest req)

Returns a link to a file in the OpenCms VFS that has been adjusted according to the web application path and the OpenCms static export rules.

The current OpenCms user context URI will be used as source of the link.

Since OpenCms version 7.0.2, you can also use this method in case you are not sure if the link is internal or external, as CmsLinkManager.substituteLinkForUnknownTarget(org.opencms.file.CmsObject, String) is used to calculate the link target.

Relative links are converted to absolute links, using the current element URI as base.

参数:

target - the link that should be calculated, can be relative or absolute

req - the current request

返回:

the target link adjusted according to the web application path and the OpenCms static export rules

CmsLinkManager.substituteLinkForUnknownTarget(org.opencms.file.CmsObject, String)

linkTagAction

public static java.lang.String linkTagAction(java.lang.String target,
                             javax.servlet.ServletRequest req,
                             java.lang.String baseUri)

Returns a link to a file in the OpenCms VFS that has been adjusted according to the web application path and the OpenCms static export rules.

If the baseUri parameter is provided, this will be treated as the source of the link, if this is null then the current OpenCms user context URI will be used as source.

Relative links are converted to absolute links, using the current element URI as base.

参数:

target - the link that should be calculated, can be relative or absolute

req - the current request

baseUri - the base URI for the link source

返回:

the target link adjusted according to the web application path and the OpenCms static export rules
