我第一次使用kohana框架,所以我按照使用" hello world"设置它的过程。程序,但我总是得到一个空白页。这是我的控制器和引导程序文件:

控制器文件:

<?php defined('SYSPATH') or die('No direct script access.');

class Controller_Welcome extends Controller {

    public function action_index()
    {
        echo "Hello, World!";
    }

} // End Welcome

bootstrap文件:

<?php defined('SYSPATH') or die('No direct script access.');
Cookie::$salt = 'foobar';
// -- Environment setup --------------------------------------------------------

// Load the core Kohana class
require SYSPATH.'classes/Kohana/Core'.EXT;

if (is_file(APPPATH.'classes/Kohana'.EXT))
{
    // Application extends the core
    require APPPATH.'classes/Kohana'.EXT;
}
else
{
    // Load empty core extension
    require SYSPATH.'classes/Kohana'.EXT;
}

看起来不错,但请使用$this->response->body('Hello, World!')代替echoinstall.php文件有效吗?你当地的网址是什么?

试试这个:

http://localhost/kohana/index.php
