Marat Radchenko commented on WICKET-609:
----------------------------------------
Solution, take two (how handles pages in different directories):
{code:java}
/**
* Calculates absolute path to url relative to another absolute url.
*
* @param requestPath absolute path.
* @param relativePagePath path, relative to requestPath
* @return absolute path for given url
*/
private static String toAbsolutePath(final String requestPath, final String
relativePagePath) {
final StringBuffer result;
if (requestPath.endsWith("/")) {
result = new StringBuffer(requestPath);
} else {
//Remove everything after last slash (but not slash itself)
result = new StringBuffer(requestPath.substring(0,
requestPath.lastIndexOf('/') + 1));
}
if (relativePagePath.startsWith("../")) {
StringBuffer tempRelative = new StringBuffer(relativePagePath);
//Go up through hierarchy until we find most common directory for both
pathes.
while (tempRelative.indexOf("../") == 0) {
//Delete ../ from relative path
tempRelative.delete(0, 3);
//Delete last slash from result
result.setLength(result.length() - 1);
//Delete everyting up to last slash
result.delete(result.lastIndexOf("/") + 1, result.length());
}
result.append(tempRelative);
} else {
//Pages are in the same directory
result.append(relativePagePath);
}
return result.toString();
}
{code}
Testing (should print 'true' three times [and prints]):
{code:java}
public static void main(String[] args) {
System.out.println(toAbsolutePath("http://aif.ru/test/test";,
"../blah/zzz").equals("http://aif.ru/blah/zzz";));
System.out.println(toAbsolutePath("http://aif.ru/test";,
"blah/zzz").equals("http://aif.ru/blah/zzz";));
System.out.println(toAbsolutePath("http://aif.ru/test/";,
"../blah/zzz").equals("http://aif.ru/blah/zzz";));
}
{code}
Usage:
{code:java}
HttpServletRequest req = ...
final String relativePagePath= RequestCycle.get().urlFor(...);
final String absolutePageUrl = toAbsolutePath(req.getRequestURL().toString(),
relativePagePath);
{code}
> Wicket should provide an easy method to generate absolute urls to
> bookmarkable pages

> Affects Versions: 1.3.0-beta1
> Reporter: Ryan Crumley
> Assignee: Alastair Maw
> Priority: Minor
> Fix For: 1.3.0-rc1

>
> Currently there is no easy way to generate an absolute url for a bookmarkable
> page. Something like getFullyQualifiedUrl(String contextRoot, Class page,
> PageParameters parameters) would be ideal.
