直接上代码：

$url = $this->getConfig ()->url ();$content = "var url={ base:'{$url->base}',css:'{$url->css}',js:'{$url->js}',img:'{$url->img}',current:window.location};";$expire = 604800;header ( 'Content-type: application/x-javascript' );header ( 'Cache-Control: max-age=' . $expire );header ( 'Accept-Ranges: bytes' );header ( 'Content-Length: ' . strlen ( $content ) );echo $content;
