如果一个网站同一套程序绑定了多个域名 www.a.com ,www.b.com,为了区分他们的robots.txt、 百度站长验证文件等,如 www.a.com/robos.txt 的内容来自于 /Virtual/www.a.com/robots.txt www.b.com/robots.txt 的内容来自于 /Virtual/www.b.com/robots.txt 的方法:RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^([a-zA-Z0-9_]{2,32}\.(xml|html|txt)) seo.php?file=$1 [L]
文件 /seo.php<?php /** * @param string $msg */ function _404($msg = ‘‘) { header(‘HTTP/1.1 404 Not Found‘); header(‘Status: 404 Not Found ‘); // 确保FastCGI模式下正常 if (empty($msg)) $msg = ‘ 404 Not Found. ‘; exit($msg); } function getExt($file) { return strrchr($file, ‘.‘); } $file = trim($_GET[‘file‘]); if (!preg_match(‘/^[a-zA-Z0-9_]{3,32}\.(html|txt|xml)$/i‘, $file)) _404(); $dir = ‘Virtual/‘ . strtolower($_SERVER[‘HTTP_HOST‘]); if (!is_dir($dir)) _404(); $filePath = $dir . ‘/‘ . $file; if (file_exists($filePath) && is_file($filePath)) { switch (getExt($file)) { case ‘.txt‘: $type = ‘text/plain; charset=UTF-8‘; break; case ‘.xml‘: $type = ‘application/xml‘; break; case ‘.html‘: default: $type = ‘text/html; charset=UTF-8‘; break; } if (!empty($type)) { header(‘Content-type:‘ . $type); } echo file_get_contents($filePath); } else { _404(); }
