我通过将图像直接添加到API响应中，创建了图像的快捷方式。

<小时>

//Add in functions.php, this hook is for  my \'regions\' post type
add_action( \'rest_api_init\', \'create_api_posts_meta_field\' );

function create_api_posts_meta_field() {
  register_rest_field( \'regions\', \'group\', array(
         \'get_callback\'    => \'get_post_meta_for_api\',
         \'schema\'          => null,
      )
  );
}

//Use the post ID to query the image and add it to your payload. 


function get_post_meta_for_api( $object ) {
  $post_id = $object[\'id\'];
  $post_meta = get_post_meta( $post_id );
  $post_image = get_post_thumbnail_id( $post_id );      
  $post_meta["group_image"] = wp_get_attachment_image_src($post_image)[0];


  //var_dump(wp_get_attachment_image($post_image)); die();
  //Different image codex return different values, narrow in on what you want

  return $post_meta;
}

Tty这个

jQuery.getJSON(\'/latest-post-as-json/\', function(data) {

    jQuery(\'#externalBlock\').append(\'<h1>\'+data.post_title+\'</h1>\');

    jQuery(\'#externalBlock\').append(data.post_content);



//etc

});
