正如@Milo所说，wordpress。com是一个独立的平台，wordpress上提供的一切。com仅对wordpress上托管的站点可用。com。jetpack插件确实为自托管网站提供了一些功能，但我不确定是哪些功能。

您所说的短代码仅在wordpress托管的网站上可用。com，而不是自托管网站。

我很快重写了script I have recently done to look for filters and action 在WordPress中获取所有可用于自托管站点的短代码。下面是函数

function get_all_filters_and_actions2( $path = \'\' )
{
    //Check if we have a path, if not, return false
    if ( !$path ) 
        return false;

    // Validate and sanitize path
    $path = filter_var( $path, FILTER_SANITIZE_URL );
    /**
     * If valiadtion fails, return false
     *
     * You can add an error message of something here to tell
     * the user that the URL validation failed
     */
    if ( !$path ) 
        return false;

    // Get each php file from the directory or URL  
    $dir   = new RecursiveDirectoryIterator( $path );
    $flat  = new RecursiveIteratorIterator( $dir );
    $files = new RegexIterator( $flat, \'/\\.php$/i\' );

    if ( $files ) {

        $output = \'\';
        $array  = [];
        foreach($files as $name=>$file) {
            /**
             * Match and return all instances of apply_filters(**) or do_action(**)
             * The regex will match the following
             * - Any depth of nesting of parentheses, so apply_filters( \'filter_name\', parameter( 1,2 ) ) will be matched
             * - Whitespaces that might exist between apply_filters or do_action and the first parentheses
             */
            // Use file_get_contents to get contents of the php file
            $get_file_contents =  file( $file );
            foreach ( $get_file_contents as  $key=>$get_file_content ) {
                preg_match_all( \'/add_shortcode\\s*(\\([^()]*(?:(?-1)[^()]*)*+\\))/\', $get_file_content, $matches );

                if ( $matches[0] )
                    $array[$name][$key+1] = $matches[0];
            }
        }

        if ( $array ) {
            foreach ( $array as $file_name=>$values ) {
                $output .= \'<ul>\';
                    $output .= \'<strong>File Path: \' . $file_name .\'</strong></br>\';
                    $output .= \'The following shortcodes are available\';

                    foreach ( $values as $line_number=>$string ) {
                        $whitespaces = \'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\';
                        $output .= \'<li>Line reference \' . $line_number . $whitespaces . $string[0] . \'</li>\';
                    }
                $output .= \'</ul>\';
            }
        }
        return $output;

    }

    return false;
}
