WP-API有钩子，比如

rest_prepare_page

以增强端点。对于每种帖子类型，给它不同的挂钩，下面的代码示例将标签添加到帖子和页面，并说明它是如何工作的。

 /** 
   * Add properties to posts and pages endpoints.
   */function wp_api_theming_posts_properties( $response ) {    

    // Set author\'s name.   
    $author = get_userdata( $response->data[\'author\'] );
    $response->data[\'author\'] = array(      \'id\' => $author->ID,        \'link\' => get_author_posts_url( $author->ID ),      \'name\' => $author->data->display_name,  );  

     // Add post classes.
        $response->data[\'post_class\'] = get_post_class( \'\', $response->data[\'id\'] ); 

    // Add categories.  
   $categories = wp_api_theming_get_post_terms( $response->data[\'id\'], \'category\' );

    if ( ! empty( $categories ) ) { 
        $response->data[\'categories\'] = $categories;
    } 

    // Add tags.    $tags = wp_api_theming_get_post_terms( $response->data, \'post_tag\' );

    if ( ! empty( $tags ) ) {   
        $response->data[\'tags\'] = $tags;    }   return $response;
   }

add_filter( \'rest_prepare_post\', \'wp_api_theming_posts_properties\' );

add_filter( \'rest_prepare_page\', \'wp_api_theming_posts_properties\' );  

/** * Get a post\'s terms with archive links. */
function wp_api_theming_get_post_terms( $id = false, $taxonomy = \'category\' ) {

   // We need an ID for this one.
  if ( ! $id ) {        
      return FALSE; 
  }     

  // Validate the taxonomy argument.      
  $valid_tax = apply_filters( \'wp_api_theming_valid_tax\', array( \'category\', \'post_tag\' ) );

  $taxonomy = ( in_array( $taxonomy, $valid_tax ) ) ? $taxonomy : \'category\';   
  // Fetch our terms.   
 $terms = wp_get_post_terms( absint( $id ), $taxonomy );    

    if ( ! is_wp_error( $terms ) && ! empty( $terms ) ) {
       // Append a link property to each term.
        foreach ( $terms as $term ) {
               $link = get_term_link( $term );
               $term->link = $link;     
        }   
    }   

 return $terms;
}
