链接到cakephp中的HTML文件

I need to show link to html file. The path to this file is root folder/test/index.html. I try using

$this->URL->build, href

but still no luck.

Put your HTML files inside cakephp webroot folder.

webroot/
  index.php
  css/
  img/
  js/
  test/   <--- html content
   index.html
   other.html

build links:

 <?php echo $this->Html->link('LINK 1','/test/index.html');
