I have a login interceptor that redirects to a login page where necessary
with a "next" parameter set to the url that was just accessed, like so :
if (user == null && LOGIN_NEEDED.contains(clazz)) {
resolution = new RedirectResolution(Login.class);
if (context.getRequest().getMethod().equalsIgnoreCase("GET")) {
((RedirectResolution)resolution).addParameter("next",
action.buildReturnUrl());
}
}
return resolution;
buildReturnUrl is defined in my base action class as :
public String buildReturnUrl() {
try {
HttpServletRequest req = getContext().getRequest();
ActionResolver resolver =
StripesFilter.getConfiguration().getActionResolver();
ActionBean bean = resolver.getActionBean(this.context,
req.getRequestURI());
String urlBinding = resolver.getUrlBinding(bean.getClass());
UrlBuilder builder = new UrlBuilder(req.getLocale(),
urlBinding, true);
builder.addParameters(req.getParameterMap());
return builder.toString();
}
catch (StripesServletException ex) {
throw new RuntimeException("failed to build url", ex);
}
}
(I resorted to this as opposed to the method shown in the Stripes book
because it does not handle clean urls properly. If you have a binding such
as "/some/path/{id}", you end up with "/some/path/foo?id=foo").
However, URLBuilder is encrypting the parameters as it builds so what is
already encrypted turns into a broken value. Since all the methods to
modify the request map in StripesRequestWrapper throw
UnsupportedOperationExceptions, I can't decrypt the encrypted parameters
(known parameter names) and then replace them so they get re-encrypted
properly by the URLBuilder.
How can I modify the request parameters to fix the double encoding issue?
Thanks
Chris
