我正在尝试将两种preg\\u匹配模式分别与|、、组合在一起，。

/blog\\/page\\/[0-9]+\\/?$/ with /tag\\/ skip in /blog/page/ and /tag/
/page\\/[0-9]+\\/?$/ with /[0-9]+\\/?$/ ex. /page/2/ and only /2/
/(page\\/[0-9]+\\/?)$/ with /([0-9]+\\/?)$/

    function redirect_pagination() {
    if(!preg_match(\'/blog\\/page\\/[0-9]+\\/?$/,|,/tag\\/\', $_SERVER[\'REQUEST_URI\'])) {
        if(preg_match(\'/page\\/[0-9]+\\/?$/,|,/[0-9]+\\/?$/\', $_SERVER[\'REQUEST_URI\'])) {
            $new_url = preg_replace(\'/(page\\/[0-9]+\\/?)$/,|,/([0-9]+\\/?)$/\', \'\', $_SERVER[\'REQUEST_URI\']);
            wp_redirect($new_url, 301);
            exit;
        }
    }
}
add_action( \'init\', \'redirect_pagination\', 1 );
