4.4 的两大特性反正在下是超级喜欢，REST API 让 WordPress 可以快捷地在移动端开发衍生产品或与其他项目融合；Embeds 加强了网站与网站之间的互通性。当然这只是一家之言，对于大多数博主来说还是显得多余些了……随手记录下禁用方法，希望对你有帮助。

 

禁用 REST API 及去除相应链接

方法一：使请求http://www.example.com/wp-json/ 后返回错误代码{“code”:”rest_disabled”,”message”:”The REST API is disabled on this site.”}

add_filter('rest_enabled', '_return_false');
add_filter('rest_jsonp_enabled', '_return_false');

方法二：彻底关闭

remove_action( 'wp_head', 'rest_output_link_wp_head', 10 );
remove_action( 'wp_head', 'wp_oembed_add_discovery_links', 10 );

 

禁用 Embeds – 官方插件 Disable Embeds

与之前被去除的 「链接」 功能一样，WordPress 官方已经为我们铺好后路——直接安装启用即可，或是将下列代码加入 Functions.php：

function disable_embeds_init() {
	/* @var WP $wp */
	global $wp;

	// Remove the embed query var.
	$wp->public_query_vars = array_diff( $wp->public_query_vars, array(
		'embed',
	) );

	// 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' );
	add_filter( 'tiny_mce_plugins', 'disable_embeds_tiny_mce_plugin' );

	// Remove all embeds rewrite rules.
	add_filter( 'rewrite_rules_array', 'disable_embeds_rewrites' );
}

add_action( 'init', 'disable_embeds_init', 9999 );

/**
 * Removes the 'wpembed' TinyMCE plugin.
 *
 * @since 1.0.0
 *
 * @param array $plugins List of TinyMCE plugins.
 * @return array The modified list.
 */
function disable_embeds_tiny_mce_plugin( $plugins ) {
	return array_diff( $plugins, array( 'wpembed' ) );
}

/**
 * Remove all rewrite rules related to embeds.
 *
 * @since 1.2.0
 *
 * @param array $rules WordPress rewrite rules.
 * @return array Rewrite rules without embeds rules.
 */
function disable_embeds_rewrites( $rules ) {
	foreach ( $rules as $rule => $rewrite ) {
		if ( false !== strpos( $rewrite, 'embed=true' ) ) {
			unset( $rules[ $rule ] );
		}
	}

	return $rules;
}

/**
 * Remove embeds rewrite rules on plugin activation.
 *
 * @since 1.2.0
 */
function disable_embeds_remove_rewrite_rules() {
	add_filter( 'rewrite_rules_array', 'disable_embeds_rewrites' );
	flush_rewrite_rules();
}

register_activation_hook( __FILE__, 'disable_embeds_remove_rewrite_rules' );

/**
 * Flush rewrite rules on plugin deactivation.
 *
 * @since 1.2.0
 */
function disable_embeds_flush_rewrite_rules() {
	remove_filter( 'rewrite_rules_array', 'disable_embeds_rewrites' );
	flush_rewrite_rules();
}

register_deactivation_hook( __FILE__, 'disable_embeds_flush_rewrite_rules' );

在此插件中意外地发现了composer.json ，是否预示着 WordPress 今后将有大变动？拭目以待。
