How to create a Wicket url that hides its parameters?

I am currently creating a set of links with this code:

BookmarkablePageLink<CheeseMain> havarti = new BookmarkablePageLink<CheeseMain>("havarti", CheeseMain.class); havarti.setParameter("Title", "Havarti"); havarti.setParameter("Group", "cheeseName"); add(havarti);

The outgoing URL is in the format https://mysite.com/;jsessionid=B85EE5CB0349CCA2FE37AF76AB5C30C1?wicket:bookmarkablePage=:com.mycompany.cheese.CheeseMain&Title=Havarti&group=cheeseName .

My problem is that I no longer want the URL of this link to be bookmarked. Ideally, I would like it to be something as simple as https://mysite.com/cheese , but I can live with an ugly URL. The important thing is that the parameters are not visible.

How do I change the way links are created? I looked at the various URL coding strategies that Wicket provides, but none of them remove parameters; they just display them differently.

Parameters are displayed in the URL only if the page is classified or the specific link is bookmarked.

If you create a Link that moves to the page using setResponsePage(Page) (passing the page instance) instead of setResponsePage(Class<Page>, PageParameters) (passing the page class), the created link will not point to the classified version of the page, but in the case of condition.

To do this, you should not call the super(PageParameters) constructor (so that there is not enough information on the page to create a stateless URL).

In this example, you can go to SecretPage through two different links, one stateless, bookmarked, and other state.

SecretPage also has two constructors. One gets PageParameters and calls super , passing it. The other receives the value directly through the construcor parameter and does not pass it to super (if he called super(new PageParameters().add("message",message) , as in a commented line, it automatically redirects the bookmarked URL).

HomePage.java:

 public class HomePage extends WebPage { public HomePage(final PageParameters parameters) { add(new BookmarkablePageLink<Void>("bookmarkable", SecretPage.class, new PageParameters().add("message", "This message will appear in the URL"))); add(new Link<Void>("instance") { @Override public void onClick() { setResponsePage(new SecretPage("This message will NOT appear in the URL")); } }); } }

homepage.html:

 <html xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd" > <body> <p><a wicket:id="bookmarkable">Bookmarkable link (stateless)</a></p> <p><a wicket:id="instance">Hidden parameters link (stateful)</a></p> </body> </html>

SecretPage.java

 public class SecretPage extends WebPage { public SecretPage(PageParameters parameters) { super(parameters); init(parameters.get("message").toString("No message!")); } public SecretPage(String message) { // super(new PageParameters().add("message", message)); // COMMENTED! init(message); } private void init(String message) { info(message); add(new FeedbackPanel("feedback")); add(new BookmarkablePageLink<Void>("back", getApplication().getHomePage())); } }

SecretPage.html

 <html xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd" > <body> <p wicket:id="feedback"></p> <p><a wicket:id="back">BACK</a></p> </body> </html>

And in order to have a simple url like http://host/app/secret , you have to install it. You can do this in your WebApplication class.

WicketApplication.java

 public class WicketApplication extends WebApplication { @Override protected void init() { super.init(); mountPage("home", getHomePage()); mountPage("secret", SecretPage.class); } public Class<HomePage> getHomePage() { return HomePage.class; } }

This example uses Wicket 1.5 (still RC4.2), and to work with 1.4.x some changes are needed (some methods and classes have been renamed or moved to different packages), but the idea is the same.

You can still use the select URL strategy and encapsulate your parameters in an inherited class, for example:

 public class Havarti extends CheeseMain { public Havarti() { super(new PageParameters("Title=Havarti,Group=cheeseName")); } }

Then you can use: new BookmarkablePageLink<Void>("havarti", Havarti.class) .
