<?php /** * HTTP API: WP_HTTP_Proxy class * * @package WordPress * @subpackage HTTP * @since 4.4.0 */ /** * Core class used to implement HTTP API proxy support. * * There are caveats to proxy support. It requires that defines be made in the wp-config.php file to * enable proxy support. There are also a few filters that plugins can hook into for some of the * constants. * * Please note that only BASIC authentication is supported by most transports. * cURL MAY support more methods (such as NTLM authentication) depending on your environment. * * The constants are as follows: * <ol> * <li>WP_PROXY_HOST - Enable proxy support and host for connecting.</li> * <li>WP_PROXY_PORT - Proxy port for connection. No default, must be defined.</li> * <li>WP_PROXY_USERNAME - Proxy username, if it requires authentication.</li> * <li>WP_PROXY_PASSWORD - Proxy password, if it requires authentication.</li> * <li>WP_PROXY_BYPASS_HOSTS - Will prevent the hosts in this list from going through the proxy. * You do not need to have localhost and the site host in this list, because they will not be passed * through the proxy. The list should be presented in a comma separated list, wildcards using * are supported, eg. *.wordpress.org</li> * </ol> * * An example can be as seen below. * * define('WP_PROXY_HOST', '192.168.84.101'); * define('WP_PROXY_PORT', '8080'); * define('WP_PROXY_BYPASS_HOSTS', 'localhost, www.example.com, *.wordpress.org'); * * @link https://core.trac.wordpress.org/ticket/4011 Proxy support ticket in WordPress. * @link https://core.trac.wordpress.org/ticket/14636 Allow wildcard domains in WP_PROXY_BYPASS_HOSTS * * @since 2.8.0 */ class WP_HTTP_Proxy { /** * Whether proxy connection should be used. * * @since 2.8.0 * * @use WP_PROXY_HOST * @use WP_PROXY_PORT * * @return bool */ public function is_enabled() { return defined('WP_PROXY_HOST') && defined('WP_PROXY_PORT'); } /** * Whether authentication should be used. * * @since 2.8.0 * * @use WP_PROXY_USERNAME * @use WP_PROXY_PASSWORD * * @return bool */ public function use_authentication() { return defined('WP_PROXY_USERNAME') && defined('WP_PROXY_PASSWORD'); } /** * Retrieve the host for the proxy server. * * @since 2.8.0 * * @return string */ public function host() { if ( defined('WP_PROXY_HOST') ) return WP_PROXY_HOST; return ''; } /** * Retrieve the port for the proxy server. * * @since 2.8.0 * * @return string */ public function port() { if ( defined('WP_PROXY_PORT') ) return WP_PROXY_PORT; return ''; } /** * Retrieve the username for proxy authentication. * * @since 2.8.0 * * @return string */ public function username() { if ( defined('WP_PROXY_USERNAME') ) return WP_PROXY_USERNAME; return ''; } /** * Retrieve the password for proxy authentication. * * @since 2.8.0 * * @return string */ public function password() { if ( defined('WP_PROXY_PASSWORD') ) return WP_PROXY_PASSWORD; return ''; } /** * Retrieve authentication string for proxy authentication. * * @since 2.8.0 * * @return string */ public function authentication() { return $this->username() .
