How to change permalinks for pages (Not blog posts)?

问题

I want to achieve something rather simple actually but can't find a solution. Instead of applying the permalink for posts, I want them applied to pages or both for that matter.

Ideally, I want to have the category in the permalink. For example:

http://www.example.com/earth/somepage
http://www.example.com/mars/anotherpage

*Where [earth & mars] are the categories. [somepage & anotherpage] are the titles of the pages.

For this example I registered the category and tag taxonomy

    function myplugin_settings() {  
    // Add tag metabox to page
    register_taxonomy_for_object_type('post_tag', 'page'); 
    // Add category metabox to page
    register_taxonomy_for_object_type('category', 'page');  
}
 // Add to the admin_init hook of your theme functions.php file 
add_action( 'init', 'myplugin_settings' );

All provided solution I came across are applied for posts. What am I missing?
