达维营-前端网WordPress 4.4更新新增了REST API功能，通过REST API可以很轻松的获取网站的数据，但是这个功能并不是每个网站都需要的，或者说我需要，但是并不希望他在head里面输出，所以给大家介绍下禁用REST API或者说移除head里面wp-json链接的方法。
禁用REST API
add_filter('rest_enabled', '__return_false');
add_filter('rest_jsonp_enabled', '__return_false');
remove_action( 'wp_head', 'rest_output_link_wp_head', 10 );
remove_action( 'wp_head', 'wp_oembed_add_discovery_links', 10 );
将以上代码添加到主题functions.php文件中即可禁用REST API并去除head里面输出的链接信息。
//This custom function should help removing all links in the header and footer.
function remove_json_api () {
// Remove the REST API lines from the HTML Header
remove_action( 'wp_head', 'rest_output_link_wp_head', 10 );
remove_action( 'wp_head', 'wp_oembed_add_discovery_links', 10 );
// Remove the REST API endpoint.
remove_action( 'rest_api_init', 'wp_oembed_register_route' );
// Turn off oEmbed auto discovery.
add_filter( 'embed_oembed_discover', '__return_false' );
// Don't filter oEmbed results.
remove_filter( 'oembed_dataparse', 'wp_filter_oembed_result', 10 );
// Remove oEmbed discovery links.
remove_action( 'wp_head', 'wp_oembed_add_discovery_links' );
// Remove oEmbed-specific JavaScript from the front-end and back-end.
remove_action( 'wp_head', 'wp_oembed_add_host_js' );
// Remove all embeds rewrite rules.
add_filter( 'rewrite_rules_array', 'disable_embeds_rewrites' );
}
add_action( 'after_setup_theme', 'remove_json_api' );
//And this snippet completely disable the REST API and shows {"code":"rest_disabled","message":"The REST API is disabled on this site."} when visiting http://yoursite.com/wp-json/
function disable_json_api () {
// Filters for WP-API version 1.x
add_filter('json_enabled', '__return_false');
add_filter('json_jsonp_enabled', '__return_false');
// Filters for WP-API version 2.x
add_filter('rest_enabled', '__return_false');
add_filter('rest_jsonp_enabled', '__return_false');
}
add_action( 'after_setup_theme', 'disable_json_api' );
//That's all.
