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;
