如何将XML-RPC API的更多选项列入白名单？
问题描述：
在将REST API端点添加到WordPress核心之前，我需要一种以编程方式更新默认情况下XML-RPC API不包含的选项的方法。它看起来像在文件中添加的选项，“WP-包括/类WP-XML-RPC-server.php”通过下面的方法：如何将XML-RPC API的更多选项列入白名单？
public function initialise_blog_option_info() {
global $wp_version;
$this->blog_options = array(
// Read only options

/**

$this->blog_options = apply_filters('xmlrpc_blog_options', $this->blog_options);
}
这里是我的编辑选项失败的尝试，让更新BLOG_URL，在我functions.php文件HOME_URL和WPCF7选项（SITE_URL和HOME_URL在原有功能是只读）：
public function blog_option_info() {
global $wp_version;
$this->blog_options = array(
// Updatable options
'blog_url' => array(
'desc' => __('WordPress Address (URL)'),
'readonly' => false,
'option' => 'siteurl'
),
'home_url' => array(
'desc' => __('Site Address (URL)'),
'readonly' => false,
'option' => 'home'
),
'wpcf7' => array(
'desc' => __('Contact Form 7 Options'),
'readonly' => false,
'option' => 'wpcf7'
),
);
$this->blog_options = apply_filters('xmlrpc_blog_options', $this->blog_options);
}
什么是白名单更多选择正确的方式，使自己能得到并通过API更新它们？
答
自己刚刚遇到这个问题，绝对没有提及如何在网上做。您的文章指出，列入白名单的选项在$ this-> blog_options中有所帮助，尽管如此谢谢！下面是代码（这是一个自定义的插件）：
<?php
include_once(ABSPATH . WPINC . '/class-IXR.php');
include_once(ABSPATH . WPINC . '/class-wp-xmlrpc-server.php');
class LSEOP_XmlRpc extends wp_xmlrpc_server {
private $version = 1.0;
public function __construct() {
parent::__construct();
$this->blog_options['permalink_structure'] = [
'desc' => __('Permalink Structure'),
'readonly' => false,
'option' => 'permalink_structure'
];
}
public static function lseop_getName() {
return __CLASS__;
}
}
add_filter('wp_xmlrpc_server_class', array('LSEOP_XmlRpc', 'lseop_getName'));
?>
有一个在插件很多其他的代码，因为我还加入了XML-RPC方法，但应该是你需要的一切。
答
如果您想通过XML-RPC添加读/写选项支持与名称NAME_OF_SOME_OPTION选项，下面的代码添加到您的functions.php：
add_filter('xmlrpc_blog_options', function($blog_options)
{
$blog_options['NAME_OF_SOME_OPTION'] = array(
'desc' => 'DESCRITPTION OF THE OPTION',
'readonly' => false,
'option' => 'NAME_OF_SOME_OPTION'
);
return $blog_options;
});
如果你希望能够到通过XML-RPC更新选项blog_url，写入以下内容：
add_filter('xmlrpc_blog_options', function($blog_options)
{
$blog_options['blog_url']['readonly'] = false;
return $blog_options;
});
