ZBlogPHP如何获取当前页面网址URL

$http_type = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') || (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https')) ? 'https://' : 'http://';  
echo $http_type . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

看着有点臃肿，好在也实现了想要的效果；
